Lake Poway Water Level Temporarily Reduced for Maintenance

Lake Poway’s water level is lower today, but it isn’t due to the current heatwave. The lake is being temporarily reduced to complete a planned maintenance project to replace a transducer.

Lake Poway serves as the City of Poway’s main water storage reservoir, with a capacity to hold more than one billion gallons of water. A transducer measures the lake’s water level and remotely sends data to the city.

The city typically takes advantage of lower summer lake levels every year as part of a process to maintain the water quality and for maintenance.  Water drawn down from Lake Poway is sent to the Lester J. Berglund Water Treatment Plant for treatment. Replacement water is added back in from supplies the city purchases from the San Diego County Water Authority.

Drinking water is not being discarded. Instead, the City of Poway is moving drinking water into the delivery system for treatment, and holding back on replenishing the lake until the maintenance project is complete.

The work creates a bonus for San Diego County’s avid fishing fans.

“It’s not unusual for the water level to be down in the lake this time of year,” said Allie Margie, Recreation Supervisor at Lake Poway. “Our night fishing and catfish restocking schedule aren’t affected – and with less water and more fish in the lake, your chances of making a catch might be better than ever.”

Poway operates a modern water treatment and distribution system. Lake Poway serves as a storage reservoir for imported water from both the Colorado River and Northern California.

Water flows through the Berglund Water Treatment Plant, where approximately three billion gallons of drinking water are treated every year for the citizens of Poway. Once treated, the drinking water enters a system of pipes, pump stations, reservoirs for delivery to customer’s homes and businesses.

Did you know?

  • The City of Poway maintains about 294 miles of water pipe.
  • There are approximately 2,345 fire hydrants throughout the city.
  • There are over 5,044 valves in the water system.
  • Employees working in the water system are required to be certified by the State of California to work in a water system.

 

OPINION: Gavin Newsom’s Plan for California Water is a Good One. Stay the Course

Gov. Gavin Newsom’s new blueprint for California water policy offers a stay-the-course agenda for projects and policies intended to help cope with a warming climate and more volatile weather patterns that already are affecting the state’s irrigation, environmental and drinking water supplies. There are no moonshots and few surprises, and that’s fine; it will be challenging enough to ensure that all Californians are hooked up to safe and reliable water supplies to meet their needs for the coming decade and beyond.

California Had a Plan to Bring Clean Water to a Million People. Then the Pandemic Hit

The water is too contaminated to safely drink, but residents of this farmworker community in the Central Valley pay $74 a month just to be able to turn on the tap at home.

Their bills are even higher if they use more than 50 gallons a day, a fraction of daily water consumption for the average California household. And when Fresno County completes a new well that has been planned for years, the price will increase again to cover the cost of treating manganese-laced water pumped from hundreds of feet below.

California Plans to Cut Detection Level for Perchlorate in Water

California water regulators announced Monday they planned to cut the level at which water suppliers must sample for and report detections of the chemical perchlorate, which has been linked to thyroid conditions.

Water suppliers in California currently must test for perchlorate in drinking water down to 4 parts per billion. The State Water Resources Control Board said it plans to cut that level to 2 parts per billion and then again to 1 part per billion in 2024.

California Adopts Definition of Microplastics in Drinking Water

In accordance with deadlines set in 2018 legislation, the California State Water Resources Control Board has adopted a definition for “microplastics” that will be used in testing of drinking water for microplastics. The Board was required, on or before July 1, 2020, to adopt a definition of microplastics in drinking water and, on or before July 1, 2021, will be required to adopt requirements for testing and reporting on microplastics in drinking water, among other things. While this development is currently focused on the testing of drinking water in California, the Board and others expect that it will form the basis of future efforts to quantify and address microplastics in the environment.

Why Limiting PFAS in Drinking Water is a Challenge in the U.S.

n article in the local newspaper caught Andrea Amico’s eye in May 2014. It reported that one of the three drinking-water wells at a sprawling business and industrial park nearby was shut down because of high levels of chemical contamination.

“Instantly, my heart sank,” says the Portsmouth, New Hampshire, woman. Amico recalls her reaction to the news: “My husband works there and he drinks water all day, and my two kids go to daycare there and they drink water all day.”

She’d never heard of the substances tainting the tap water—Portsmouth was one of the first communities in the US to discover these chemicals in public drinking water. Amico, who holds a master’s degree in occupational therapy and works in health care, started researching health effects from these contaminants and at first found little information.

Today, the situation has changed.

What Happens When a Drinking Water System Fails? Ask This Small California Town

Residents in Earlimart, California, lost water service when a 50-year-old well on Mary Ann Avenue failed in late May.

When it came back on, the main source of drinking water for more than 8,000 residents became a well contaminated with a chemical from banned pesticides. And most residents didn’t know.

Poway Report Shows Drinking Water is Safe and High-Quality

The City of Poway’s drinking water remains high-quality according to the city’s 2019 annual Water Quality Report.

The annual publication is a state and federal requirement that provides test results of water quality analysis conducted in 2019, according to a press release from the city. It is also called a Consumer Confidence Report and is intended to educate the public on the extensive monitoring done on tap water and the findings of those tests.

Nevada Mulls EPA Reversal of Obama Era Drinking Water Rules

The Trump administration has decided a chemical with a notorious legacy in Nevada will not be regulated in drinking water, but state officials say the reversal of the Obama-era policy shouldn’t result in any decline in drinking water standards across the state.

Arizona Starts Talks on Addressing Dwindling Colorado River

Arizona is getting a jump start on what will be a yearslong process to address a dwindling but key water source in the U.S. West.

Several states and Mexico rely on the Colorado River for drinking water and growing crops. But climate change, drought and demand have taken a toll on the river that no longer can deliver what was promised in the 1920s.

Arizona, New Mexico, Colorado, California, Utah, Wyoming and Nevada have been operating under a set of guidelines approved in 2007. Those guidelines and an overlapping drought contingency plan will expire in 2026.
