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.

City of San Diego May Release Water from Lake Hodges in Coming Months

/in , , /by /Times of San Diego

The city of San Diego may release water from Lake Hodges reservoir into San Dieguito River in coming months if heavy rain raises the water level above the maximum permitted.

For safety reasons, the California Division of Safety of Dams has determined that the water level should not be above 295 feet, which is 20 feet below the spillway elevation. If the water nears that level when rain is forecast, city officials will likely open valves at the dam for a controlled release of some of the water. The released water will enter San Dieguito River and eventually the Pacific Ocean.

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.

Water Conservation Garden Celebrates 20th Anniversary Nov. 16

/in , /by

Twenty years ago, people who saw a need to help people conserve water and preserve San Diego’s environment conceived the idea for a demonstration garden.

The Water Conservation Garden celebrates its 20th-anniversary Saturday, November 16 at 5 p.m. with a benefit concert featuring food and drink stations, dancing, auction items and live music provided by The Mighty Untouchables. More information and tickets are available on The Garden’s website.

Native San Diegan Jon Foreman of the Grammy-award winning band Switchfoot is among The Garden’s newest fans after a recent visit.

“It has been an amazing journey,” said CEO Jennifer Pillsbury. “We run six acres with educational exhibits for the public, but we also have a huge education program for the public. Last year we had 42,000 visitors and reached 88,000 kids. When we first opened, we were excited about 1,000 visitors.”

Water agencies and municipalities worked together to bring The Garden to life

A task force of water agencies and municipalities conceived The Garden in response to six years of drought in San Diego County.

Otay Water District, Helix Water District, and Cuyamaca College kick-started the effort in 1990. By 1992, the San Diego County Water Authority, City of San Diego, and Padre Municipal Water District joined the effort, forming the original Water Conservation Authority.

The following year, the Grossmont-Cuyamaca Community College District approved the establishment of a 4.5-acre Water Conservation Garden adjacent to Cuyamaca College. With $700,000 in donated services, products, and labor from local nurseries and members of the California Landscape Contractors Association, the Water Conservation Garden came to life. San Diego County Supervisor Dianne Jacob presided over its grand opening in May 1999.

Over the past 20 years, The Garden has added its popular children’s exhibits, bird and butterfly gardens, the Dorcus Utter Memorial Sensory Garden, and the Dorcus Butterfly Pavilion.

“The Garden is here to inspire everyone to use all natural resources efficiently, not just water,” said Pillsbury. “When people see proper irrigation and the right plants in the right location with the right soil, having everything working together can be beautiful and efficient.”

Inspiring positive change in the living environment

The Water Conservation Garden has been governed as an independent nonprofit organization under its own Board of Directors since 2011. Memberships, donations, grants, facility rentals, gift shop sales, and water district dues fund operations.

With additional land donated by Cuyamaca College, The Water Conservation Garden now covers six acres of displays showcasing water conservation through its themed demonstration gardens and how-to displays on mulch and irrigation.

Students in the Cuyamaca College Ornamental Horticulture program benefit from hands-on education just steps away from their classrooms.

“Students come through and learn plant identification and experience lab learning,” said Pillsbury.

New smart classroom available soon at The Garden

The Garden will open a new smart classroom available for business retreats, meetings, and seminars. Pillsbury also hopes to book more events in the 300-seat amphitheater.

Through its evolution and innovation, the mission of The Water Conservation Garden remains the same as it did on its opening day 20 years ago: to inspire positive change in the living environment through water conservation and the protection of natural resources.

“We’re here to educate the community on efficient water use, but we also want to be a spot where people can come learn and explore together in so many ways,” said Pillsbury.

Admission to The Garden is free. Docent-led tours take place on the first Saturday of each month at 10 a.m.
