San Diegans #AskAnExpert Reservoir Recreation Questions

Reservoir Keeper Viviana Castellon shared her expertise with citizens during the City of San Diego’s #AskAnExpert series on Instagram as part of the City’s community outreach to citizens. The City regularly offers the opportunity for the public to ask employees about its services including parks, libraries, streets, and water.

“We find that it’s a great way to get general information about City services to the public,” said Arian Collins, public information officer with the San Diego Public Utilities Department.

Castellon answered several questions about the recreation offered at the City’s lakes and reservoirs.

Can you rent boats at City of San Diego reservoirs?

Yes, the reservoirs do have boat rentals through the concessionaires. You can view the hours of operation and rentals fees online.

Is stand-up paddleboarding allowed at any City of San Diego reservoir?

Yes, Hodges Reservoir offers stand-up paddleboarding on Wednesday, Saturday, and Sunday from the beginning of February through the end of October.

Can you swim at City of San Diego reservoirs?

No. What are commonly referred to as the San Diego City lakes are actually impounding reservoirs that are part of the City’s municipal water-supply system. The State Water Resources Control Board approves the different recreational activities that can occur on our reservoirs and swimming is not included in our current domestic water supply recreational permit.

Can you water ski at the City of San Diego reservoirs?

Yes, San Vicente Reservoir offers water-skiing and wakeboarding from May through October Thursday through Sunday.

Residents who would like to keep up with the latest information about the City’s reservoirs and lakes as well as other City of San Diego services can learn more at the City of San Diego website, as well as follow the City’s Instagram account for more #AskAnExpert opportunities.

Pumped Energy Storage-Lake Hodges-Olivenhain

Water Agencies Help Address California Energy Shortages

Water agencies across San Diego County are doing their part to stabilize the state’s power grid during this week’s heatwave by generating hydropower and altering operations to trim electricity demands – and they are offering long-term solutions to reduce future energy shortages.

The California Independent System Operator issued a statewide Flex Alert from Sunday through Wednesday, calling for reduced electricity use in the afternoon and evening to limit power outages. Blackouts could affect hundreds of thousands of San Diego County residents, if extreme heat persists.

Producing and conserving power during energy shortages

At Lake Hodges, the Water Authority is running its pumped energy storage facility to meet peak demands. As water flows down the pipeline from Olivenhain Reservoir into Lake Hodges, it generates up to 40 megawatts of energy on demand, helping to manage temporary peak electrical demands or unplanned outages. Then, the water is pumped back to Olivenhain Reservoir when power demands are low to restart the cycle.

In addition, water agencies are taking numerous actions to conserve energy. For the Water Authority, the strategy includes temporarily reducing drinking water production at the Claude “Bud” Lewis Carlsbad Desalination Plant in collaboration with Poseidon Water.

The Carlsbad Desalination Plant is the largest, most technologically advanced and energy-efficient desalination plant in the nation, and it has produced more than 62 billion gallons of drinking water for San Diego County since it began operations in December 2015.

Starting Monday, the plant ramped down operations, making an additional 8 megawatts of power available for other uses. If more load reductions are necessary over the next several days, additional curtailment may be considered at the plant. The power provided by the plant could help offset current energy shortages.

“This partnership by the Water Authority and Poseidon is another reminder of the value of the cutting-edge technology and local control at the Carlsbad plant,” said Jim Madaffer, chair of the Water Authority’s Board of Directors. “Operations are flexible and the technology is nimble, so production can be ramped up and down in response to local needs.”

Water agencies respond to energy shortages

In addition, local and regional water agencies are temporarily shutting down or reducing flows at pump stations and turning off HVAC systems in the afternoons. Some agencies also have the ability to convert to less energy-intensive treatment, for instance, by replacing ozone with chlorine.

Local water agencies also are tapping their significant backup power generation capacity – at their own expense – to ease the strain on the energy grid, following Governor Newsom’s executive order that suspends some regulatory requirements for those units during this emergency event. Local agencies are also looking to work with the administration to ensure that their backup generation capacity can be used proactively to help avoid future energy shortages.


Pumped Energy Storage-WNN-June 2020-graphic

Pumped energy storage facilities are part of an integrated and sustainable energy system that
includes the production, storage and distribution of clean energy.

Environmentally friendly pumped storage project proposed

Beyond the immediate concerns, this week’s heat wave has highlighted the need to increase large-scale energy storage as the state moves toward a goal of 100% renewable energy by 2045. Put simply, the sun doesn’t always shine and the wind doesn’t always blow enough to meet demands, so the state needs more capacity to store peak renewable energy production for peak demand periods.

The Water Authority has proposed building a large-scale pumped storage project at the San Vicente Reservoir near Lakeside. Pumped energy storage projects are designed to store excess renewable energy from solar and wind when it’s available, and then discharge that energy when energy demands increase and renewable energy is scarce.

Solutions for long-term energy challenge

A 2019 white paper highlighted the importance of pumped energy storage to California’s future.

“Our current situation is the direct result insufficient planning; the state clearly needs additional energy storage now and will need much more in the future,” said Gary Bousquet, energy program manager for the Water Authority. “Environmentally friendly pumped storage projects should be started immediately to address this shortfall, or power reliability will get significantly worse. The San Vicente project can be started now at no cost to taxpayers – users only pay when the project comes online.”

Reservoirs Begin Reopening to Recreational Use Countywide

City of San Diego lakes and reservoirs previously closed in response to the coronavirus pandemic are now in the process of reopening for public recreation.

“A lot of San Diegans have a passion for fishing and boating, and we’ve been able to partner with the County [of San Diego] to reopen all of our lakes and reservoirs to the public,” said San Diego Mayor Kevin Faulconer.

El Capitan Reservoir and Upper Otay Reservoir reopened on June 6. San Vicente Reservoir will open to the public June 13.

Three reservoirs will re-open in July: Lake Hodges on July 1, Sutherland on July 3, and Barrett on July 8.

Miramar, Murray, and Lower Otay Reservoirs have opened in mid-May.

New safety and cleaning protocols initiated with the re-openings in May will remain in place at all reservoirs. The reservoirs will be open during regular business hours for walking, jogging, cycling, fishing, and boating. Normal fishing and boating fees will apply.

“As we have seen from the thousands of calls, emails, and letters to City Hall, fishing is more than a hobby, it’s a passion,” said San Diego City Councilmember Scott Sherman. “Our lakes and reservoirs are too important of a recreational asset to keep closed and I am thankful they will be opened soon.”

Lake Jennings in Lakeside, operated by the Helix Water District, will also reopen for recreation and day-use on Saturday, June 13. Hours are limited to weekends from 6 a.m. to 3 p.m. Fishing and day-use visitors must wear masks and adhere to social distancing. The Bait and Tackle Shop will be open with restrictions. Shore fishing and private boat launching are available, but no boat rentals, night fishing, or fish stocking at this time.

In addition, Lake Jennings recently reopened for camping on June 5 with restrictions in place limiting use to every other campsite, and only by members of the same household. See the complete list of restrictions at the Lake Jennings website.

“We are thrilled to be able to reopen in compliance with the County regulations,” said Kira Haley, Lake Jennings recreation manager. “We really appreciate your understanding in this difficult time while we continue to work hard to keep our community safe.”

The public will be asked to observe COVID-19 preventative measures, including mandates requiring face coverings and physical distancing.

Santee Lakes, operated by the Padre Dam Municipal Water District, expanded recreational use including fishing with some restrictions on May 16. All activities with physical distancing are allowed including jogging, bike riding, roller-skating. A facial covering is not required during physical activities but must be in your possession. Physical distancing and possession of a facial covering are required while fishing. The lake’s campsites have remained open throughout the pandemic, but campers must practice social and physical distancing while on site.

County of San Diego to help cover costs

The cost of reopening the City of San Diego’s additional reservoirs is approximately $1 million. Funding identified through a tentative cost-sharing agreement with the County of San Diego will be limited to covering enhanced staffing costs for ensuring public health is maintained in response to the COVID-19 pandemic. Both the City Council and San Diego County Board of Supervisors will need to approve the agreement.

California Senate Leaders Propose Economic Recovery Plan

San Diego County Water Authority Board Chair Jim Madaffer today praised planning efforts by state Senate President pro Tempore Toni G. Atkins of San Diego and other state Senate leaders to help guide California’s economic recovery from the COVID-19 pandemic.

The senate plans include funding to create jobs, boost infrastructure investments and to protect renters and landlords.

“We are very appreciative of President pro Tem Toni Atkins’ efforts to advance immediate action on economic recovery and creative solutions to jump-start California’s economy without exacerbating the already-challenging fiscal conditions being experienced at the state and local government levels,” Madaffer said. “We look forward to engaging on the details and partnering with the state to move forward on shovel-ready water and energy infrastructure projects that can help the state’s economic recovery gain traction.”

The Water Authority pledged to work with Sen. Atkins as the Legislature begins the challenging – but necessary – work of crafting comprehensive and responsible solutions to address the crisis and begin the task of restoring the economy.

Economic Recovery Fund

One of the proposals would create a $25 billion Economic Recovery Fund through establishment of prepaid future tax vouchers from 2024 through 2033. The funds could be used to accelerate infrastructure projects and boost the green economy.

It would also create jobs and provide a myriad of services and resources, from small business and worker assistance and retraining to wildfire prevention response and schools most harmed by campus closures.

In addition senate leaders outlined a budget approach to help the state rebound from COVID-19.

“Our goal is to offer ideas for our state budget and economic recovery that take a responsible approach to planning for our state’s spending, while also keeping in mind the needs of Californians, millions of whom have been adversely impacted by the pandemic,” said Atkins.

Freshwater Fishing Flourishes at San Diego Region’s Reservoirs and Lakes

San Diego County’s freshwater fishing in area reservoirs and lakes managed by the region’s water agencies attracts expert anglers and beginners alike.

Of San Diego County’s 24 reservoirs and lakes, 18 allow fishing. Bryan Norris, Reservoirs and Recreation Program Manager for the City of San Diego, oversees eight locations offering recreational opportunities, including fishing.

“We are the largest provider of recreation for the domestic water supply in California,” said Norris. “No other program provides recreation at eight different reservoirs. The City of San Diego is considered a pioneer in these offerings. It’s really something that gets overlooked.”

What people often call lakes in the City of San Diego are actually water supply storage reservoirs and part of the City’s municipal water supply system operated by the City’s Public Utilities Department. The nine reservoirs are Barrett, El Capitan, Hodges, Lower Otay, Miramar, Murray, San Vicente, Sutherland, and Upper Otay. Lake Hodges, Sutherland, and Barrett Lake close during winter months; the remaining five are open year-round.

Lake Murray in La Mesa and Miramar Lake in Scripps Ranch are stocked regularly with trout by the California Department of Fish and Wildlife. The remaining fish species are self-sustaining, such as bass, catfish, bluegill, and crappie.

“We’re so well known for our bass fisheries at the city lakes,” said Norris. “We have multiple tournaments at our reservoirs, it’s our top fishery. They are serious, it’s like any organized sport.”

Trout most popular at Lake Jennings

Lake Jennings in Lakeside, operated by the Helix Water District, opened its popular trout season November 15. It stocks 20,000 pounds of trout annually on a biweekly schedule between November and April, and 10,000 pounds of catfish in the summer months. It recently received 2,500 pounds of rainbow trout stock from Wright’s Rainbows in Thatcher, Idaho.

Helix Recreation Manager Kira Haley said she works closely with the California Department of Fish and Wildlife to determine the correct timing for stocking the lake for eager fishing enthusiasts.

“If you don’t stock it, they won’t come,” said Haley. “We base the timing on water temperature for the trout, between November and April, when it’s low enough for trout to survive. When it’s not low enough, we stock catfish.”

In addition, large-mouth bass, red-ear sunfish, and bluegill, as well as channel and blue catfish live in Lake Jennings. Sign up for the Lake Jennings Fish Report online to see what fish are biting.

Haley says she enjoys her new role as a fisheries manager.

“I wouldn’t have called myself a fisherman before I got here,” said Haley. “I know more about fish than I ever thought I would know.

“It’s a very active community. They care so much about the lake and the health of the fish and the fisheries. It’s a great group of people to work with. Most fishermen are good stewards of the land itself. They see a piece of trash, they pick it up.”

Santee Lakes a popular family fishing stop

Santee Lakes, operated by the Padre Dam Municipal Water District, also stocks 12,500 pounds of trout and 24,000 pounds of catfish annually in the fall months for its anglers.

Norris hopes more people will visit and enjoy an escape from everyday urban life.

“There are so many reservoirs around the county that provide recreational opportunities; it’s unfortunate. Everyone thinks of beaches when they think of San Diego,” said Norris.

Easier access to recreation information on new website

As part of an ongoing effort on making it easier for the public to access recreation information, the City of San Diego reservoir lakes website has been revised and enhanced.

The website features fishing, hunting, and recreation information, an interactive map, and a photo gallery. New graphics help anglers determine the types of fish available at the City’s reservoirs. Expanded details provide users with access to the fish catch report and details about boating and permits as well as employment and volunteer opportunities.

Water Authority Celebrates 75 Years With Member Agencies

Ramona Municipal Water District is among the San Diego County Water Authority’s 24 member agencies that are recognizing CWA’s 75th anniversary.

Denise Vedder, director of public outreach and conservation for CWA, announced the milestone and thanked the RMWD representatives for their support at Oct. 8 district board meeting.

California’s Clean Energy Conundrum

San Diego – While California draws nearly one third of its power from renewables, solar and wind energy systems are periodically pulled offline because there’s not enough demand when the wind is blowing and the sun is shining. These so-called “curtailments” increased significantly between 2014 (when they were almost non-existent) and today. They could soon become a major barrier to a more sustainable future as more and more renewable energy sources are developed to meet peak demands.

Thankfully, California water agencies are well-positioned to play a pivotal role with a solution that makes the state’s electrical grid more flexible, stable and efficient. Strategic deployment of large-scale, long-duration pumped storage facilities could minimize curtailments and provide many other benefits. That would help California achieve its aggressive targets to supply at least 60 percent of the state’s energy from renewables by 2030 and 100 percent from clean energy sources by 2045.

San Diego’s Water Portfolio Approach ‘Model for California’

State officials Thursday toured San Diego County water infrastructure to get a first-hand look at the region’s successful water portfolio approach for supply diversification.

California Natural Resources Agency Secretary Wade Crowfoot, Deputy Natural Resources Secretary Thomas Gibson, State Department of Food and Agriculture Secretary Karen Ross, and State Water Resources Board Chair E. Joaquin Esquivel were here to assess the region’s water projects as part of their new role in developing a water portfolio strategy for the state.

Portfolio approach benefits region

“The region is proof that the portfolio approach works,” said Water Authority Board Chair Jim Madaffer. “The Water Authority and its 24 member agencies continue to develop local projects and explore opportunities that would benefit the region, the state, Mexico and the Southwest.”

At a luncheon meeting and panel discussion at University of California, San Diego following the tour, the agency officials joined a group of more than 150 people to hear how the portfolio approach can help California and the Southwest meet water supply challenges.

Along with the Water Authority Board of Directors, elected officials, business, community and state and local leaders gathered in an auditorium at the Southwest Fisheries Science Center on the La Jolla campus.

Jim Madaffer and Water Portfolio approach

“The state needs to look at a global approach to managing water,” said Water Authority Board Chair Jim Madaffer.

Madaffer said during the meeting that San Diego’s portfolio approach has been successful in increasing the region’s water supply reliability through diversification and innovation.

“The Water Authority’s model is one that can be replicated across the state to help ensure a secure water future for all Californians,” said Madaffer.

State agency leaders echoed Madaffer’s comments.

“San Diego has been a leader in the water portfolio approach,” said Wade Crowfoot. “We have to make the investments to build regional water resilience as part of the Governor’s order to develop a portfolio to manage water in California.”

Water resilience portfolio for 21st century 

The Water Authority invited the officials to visit after Gov. Gavin Newsom issued an Executive Order in April, directing state agencies to “prepare a water resilience portfolio that meets the needs of California’s communities and environment through the 21st century.”

In his May letter to Newsom, Madaffer thanked the governor for the “wisdom and leadership” with the issuance of Executive Order N-10-19, and invited the governor to tour San Diego County’s cutting-edge water facilities.

Newsom’s order also directed his administration to “identify and assess a suite of complementary actions to ensure safe and resilient water supplies, flood protection and healthy waterways for the state’s communities, economy and environment.”

The California Natural Resources Agency, the California EPA, and the California Department of Food and Agriculture, in consultation with the Department of Finance, were directed by Gov. Newsom to, among other tasks, “identify key priorities for the administration’s water portfolio moving forward.”

“Governor Newsom wants us to think long and broadly on water,” said Crowfoot. “He wants us to get away from the silos and conflicts on water in California – the mindset of environment groups versus farmers, north versus south, urban versus rural – and work together on water resiliency.”

Significant investments in regional water strategy

“The Water Authority and its 24 member agencies have made significant investments in the last two decades to diversify our water supply, creating a portfolio of resources to support our region’s 3.3 million people and $231 billion economy,” said Madaffer.

During the tour, the officials got a first-hand look at some of those investments, including the San Vicente Reservoir, Olivenhain Reservoir, and the Claude “Bud” Lewis Carlsbad Desalination Plant.

Global Warming creates water supply challenges

Scripps Institution of Oceanography research meteorologist Dan Cayan told the audience that temperatures and dry spells will increase in California in the future, making water storage, conservation, and forecasts even more critical.

“Global warming climate models show the Sierra Nevada snow pack will be 50% less in 2090 than today’s average April 1 snowpack,” said Cayan.

Cayan said observations and climate model projections indicate climate change is occurring and will grow stronger. California should expect 1.5-2 degrees Fahrenheit warming by 2050, he said.

New regional pipeline study

Water Authority Assistant General Manager Dan Denham described a new study that will explore the viability of a regional pipeline to transfer water from the Colorado River to benefit multiple users in San Diego County and across the Southwest.

The pipeline system is one of a handful of ideas being discussed by San Diego County water leaders to enhance partnerships and solutions that make sense locally and more broadly as part of Governor Newsom’s Water Portfolio Program to develop resiliency statewide.

Map indicates three potential routes for a proposed regional pipeline system that would move Quantification Settlement Agreement water directly from the Imperial Valley to San Diego. Two of the routes (the light blue and purple lines) follow a southern route. The third proposed route, (shown in both a yellow and darker blue line) follows a northern path. Graphic: Water Authority

Creating a pipeline to transfer Colorado River water to the San Diego region has been studied periodically over decades.

But the new study is focused on how a regional pipeline could provide multiple benefits as part of a long-term water management strategy for California and the Southwest.

The expanded review will consider a system that could create much-needed storage opportunities for the Imperial Irrigation District that could support agriculture while addressing critical issues like the Salton Sea and the need for more renewable energy development.

Pumped Hydro 2 - SanV-WaterAuthority-May 2019

Water Authority Supports Bill to Spur Pumped Storage Projects

A bill that the San Diego County Water Authority’s Board of Directors voted to support in March is scheduled for a hearing Thursday in the state Senate Appropriations Committee. The proposed state legislation promotes the development of pumped hydroelectric storage projects to help meet state energy and climate goals.

Senate Bill 772 by Sen. Steven Bradford of Gardena promotes the development of pumped hydroelectric storage projects to help meet state energy and climate goals.

The Board’s support for the legislation followed the March release of a research paper from a team led by UC San Diego Professor David G. Victor that emphasizes the benefits of expanding pumped hydro energy storage as a cost-effective way to help California meet its renewable energy goals and reduce greenhouse gas emissions.

Read the Pumped Energy Storage report here.

The Water Authority and the City of San Diego are exploring a potential pumped storage energy project at the San Vicente Reservoir that could store 4,000 megawatt-hours per day of energy, or 500 megawatts of capacity for eight hours.

Energy generated by renewable sources, like wind and solar, can be captured by energy storage facilities and then distributed then needed. Batteries and pumped energy storage will provide the needed energy storage for both short-term needs (batteries, less than 4 hours) and long-duration needs (pumped energy storage, 8 hours or more).

Large-scale, long-duration renewable energy source

A key to the San Vicente concept and others is development of statewide institutional and regulatory support for large-scale, long duration energy storage lasting up to eight hours. Pumped storage projects store solar and wind power during low-demand periods for use during high-demand periods, such as evenings when people are cooking, washing clothes and running air conditioners.

The State Energy Resources Conservation and Development Commission has identified bulk energy storage – including pumped hydroelectric storage – as a core strategy for integrating renewable energy resources into the California electrical grid and reducing greenhouse gases.

In addition, the white paper stresses the need for new state policies that will ensure that pumped energy storage projects enter commercial operations when they will be critically needed.

“To be consistent with California’s energy vision, active new policy support is needed to facilitate the development of pumped energy storage,” according to Victor’s paper. “Those policies should recognize the long lead times in building pumped energy storage projects (5 to 10 years). New policy efforts must begin now.

“Among the needed actions are state-backed support for some early projects that would jump start investment in this proven technology. This support can demonstrate viable business models and investment strategies that will pave the way for more private sector-led projects in the future.”

Providing ratepayer benefits

Pumped energy storage projects work like giant batteries by storing excess renewable energy during the day, when renewable power production peaks. Energy is released from the “battery” in the evening, when energy use increases, and renewable energy is not available.

Keeping the electrical grid reliable requires not only short-term energy storage, but long-duration, large-scale storage.

“Many expert studies have been performed that demonstrate the value of pumped energy storage, including CAISO’s Bulk Energy Storage Case Study, which found that a 500 megawatts (MW) pumped energy storage project in Southern California would provide ratepayers with a savings of up to $51M per year from improved efficiencies in system operation,” according to Victor’s white paper.

“Without significant new large-scale energy storage, California will likely be required to import more energy from other states, including potentially power generated with higher carbon emissions, such as coal,” the paper said. “The State will be unable to meet its renewable and climate goals reliably without large-scale energy storage.”

SB 772 is an attempt to address some of the issues identified by Victor and others. The legislation would require the California Independent System Operator, which runs the state’s power grid, to create a competitive bidding process by June 2022 to acquire a substantial quantity of long-duration energy storage – the type created by pumped hydroelectric storage.
