New Oxygenation System to Improve Reservoir Water Quality

/in , /by

The City of San Diego’s Public Utilities Department last week took a major step toward completing an innovative project to improve water quality in Lake Hodges. A newly installed oxygenation system, designed by city engineers, will introduce highly oxygenated water to the bottom of the reservoir to reduce the accumulation of excess nutrients and harmful algae growth.

The increase of nutrients and algae in the water has been caused by human activities in the watershed upstream of the reservoir, including residential and commercial development, agriculture, and land clearing. Degraded water quality can restrict the ability to move water in and out of the reservoir.

“The ‘Speece cone’ is a fairly unique method for adding oxygen to a reservoir – there are only a few of them in the world,” said Jeff Pasek, project manager at the City of San Diego Public Utilities Department. “This project derived from a planning study that was done about five years ago, which identified oxygenation using the ‘Speece cone’ as being the most cost-effective way of addressing the water quality problems in Hodges.”

Last week, the 130,000 pound cone – named after the inventor of the technology, Richard Speece – was lowered eighty feet to the bottom of the reservoir.

Streamlined operation for maximum efficiency

The precisely coordinated operation involved lifting the 20-foot tall stainless steel cone with a large crane, while simultaneously driving a barge out from underneath. Once the cone was lowered into the water, divers headed to the bottom of the reservoir to unhook the cone from the crane, check to make sure it settled in the correct spot, and fasten it down.

In order to build a solid foundation underwater, crews excavated approximately 11 feet of silt from the bottom of the reservoir and constructed a concrete base. Before submerging the cone, crews installed and tested a pump that will move water through the cone. A large diffuser pipe was then lowered and connected to the cone by divers. The diffuser will distribute the oxygen-rich water throughout the reservoir.

Local and regional benefits at Hodges Reservoir

Hodges Reservoir is owned and operated by the City of San Diego, and it serves the San Dieguito Water District and the Santa Fe Irrigation District. It is connected to the San Diego County Water Authority’s Olivenhain Reservoir as part of the Emergency & Carryover Storage Project, which is designed to ensure regional water reliability in case of emergencies or if the region is cut off from imported water supplies.

“There are multiple benefits to this project – first and foremost being the water quality improvements for Hodges Reservoir,” said Goldamer Herbon, a senior water resources specialist at the Water Authority. “Ancillary benefits include operational flexibility for regional supply benefits and preventing the accumulation of mercury, which can be harmful to people and wildlife that eat fish from the reservoir.”

The California State Department of Water Resources awarded the City of San Diego a $3.4 million grant funded by the San Diego Integrated Regional Water Management program to complete the oxygenation project, which began in February 2019.

San Diego County Water Authority Special Agricultural Water Rate program

New Agricultural Water Rate Program Benefits San Diego County Growers

/in , /by

The San Diego County Water Authority Board of Directors Nov. 21 approved a new and permanent Special Agricultural Water Rate program structure that offers lower water rates to farmers in exchange for lower water supply reliability.

Unlike the current temporary program, the structure of the new water rate program will let new participants join as a way to strengthen the region’s multi-billion-dollar agriculture industry.

New ag water program rates will be determined in the spring of 2020 as part of the Water Authority’s annual rate-setting process. The program will take effect January 1, 2021, replacing the current program that sunsets at the end of 2020. Additional program details, such as the signup process and qualifying criteria, also will be developed early next year.

Special water rate program supports regional farm economy

Farmers and growers who participate in the new program will continue to receive a lower level of water service during water shortages or emergencies, allowing the Water Authority to reallocate those supplies to commercial and industrial customers, who pay for full reliability benefits.  In exchange, participating farmers are exempt from fixed water storage and supply reliability charges. Under the current temporary program in 2020, participants will pay $1,231 per acre-foot for treated water, while municipal and industrial users will pay $1,686 per acre-foot.

“Creating a permanent program will benefit all regional water users,” said Water Authority Board Chair Jim Madaffer. “It helps farmers sustain their operations – and thousands of jobs – while providing a benefit to residential and commercial water customers in the event of future water supply reductions.”

San Diego County leads nation in production of nursery crops and avocados

“Every farmer in the county supports the special rate,” said Hannah Gbeh, executive director of the San Diego County Farm Bureau. “The agriculture community stands ready to provide significant water cutbacks in times of need, such as drought or emergency repairs.”

San Diego County is unusual among major metropolitan areas in the United States because it includes one of the nation’s most valuable and productive farm sectors adjacent to one of the nation’s largest cities.The region sustains 3.3 million people and a $231 billion economy thanks to decades of regional investments in water supply reliability projects, including the nation’s largest seawater desalination plant and the biggest conservation-and-transfer agreement in U.S. history.

Input from growers and farmers for agricultural water rate program

The Water Authority has provided lower-cost water to growers in exchange for lower reliability since October 2008, when the Metropolitan Water District of Southern California phased out a similar program. Since that time, the temporary Water Authority program has continued with a series of extensions set to expire at the end of 2020.

The new program was developed by the Water Authority’s Fiscal Sustainability Task Force, which is assessing a variety of issues to ensure the agency’s long-term financial health. Regional farming leaders provided input to the task force on the parameters of the new program.

Board Supports Countywide Vote on Potential Member Agency Detachment

/in , /by

The San Diego County Water Authority’s Board of Directors last week authorized actions to seek to ensure all San Diego County voters are heard on plans by the Rainbow and Fallbrook water agencies to leave the regional water wholesaler and instead join a Riverside County water agency.

The Board of Directors approved a resolution to ask the San Diego Local Agency Formation Commission – known as San Diego LAFCO – to require approval by voters across the Water Authority’s service area of any proposed “detachment” by the Rainbow Municipal Water District and the Fallbrook Public Utility District from the Water Authority. Detachment from the Water Authority has potential impacts for water agencies, fire districts and water ratepayers across San Diego County.

Water Authority Moves to Advance Settlement Over MWD Rates

/in , /by

The San Diego County Water Authority’s Board officers Thursday thanked the Metropolitan Water District of Southern California for making a public offer to settle litigation over MWD’s rates, and directed staff to take the following actions:

  • Schedule special Board meetings in December and January to expedite the process in hopes of reaching a conclusion in early 2020; and
  • Draft a durable, public and mutually beneficial settlement offer for review by the Water Authority Board; and
  • Invite MWD General Manager Jeff Kightlinger to discuss settlement with the Water Authority Board and schedule a reciprocal visit by Water Authority General Manager Sandy Kerl to MWD’s Board.

Commitment to settlement of MWD rates remains strong; ratepayer protections critical to any deal

“Given MWD’s current willingness to discuss settlement in a fully transparent and public process, the Water Authority is more optimistic than ever that an enduring settlement can be reached,” Water Authority Board Chair Jim Madaffer said after Thursday’s (Nov. 21) Board meeting.

“We must carefully consider all aspects of an agreement that will affect our economy, children and grandchildren,” Madaffer said. “That’s why we welcome the opportunity to engage fully with MWD in a public process. Discussions directly with the general managers will increase the likelihood of finding common ground early in the new year.”

MWD’s settlement proposal on Nov. 15 marked the start of public negotiations following more than a year of confidential discussions that didn’t yield an agreement. It followed on letters from the Water Authority to MWD on Nov. 8 and Nov. 12 stating the Water Authority’s belief that the agencies were nearing a point where they could soon resolve most or all of the litigation.

“We appreciate MWD’s desire to resolve our differences, and we are fully engaged with the same goal,” said Water Authority Board Secretary Christy Guerin, who is leading the agency’s settlement efforts on behalf of the Board of Directors.

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

/in , /by

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.

San Diego County’s year-round lakes also offer hiking, walking, biking, and picnicking.

Three of San Diego’s reservoirs (Lake Hodges, San Vicente, and El Capitan) allow windsurfing, water skiing, and the use of personal watercraft. Stand up paddle boarding was added this year at Lake Hodges. Barrett Lake and Lake Sutherland offer bird hunting.

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.
