What New Rules for Colorado River Would Mean for San Diego

California and six other states that rely on the Colorado River have been unable to agree on how to divide its water for years. Now, the federal government is stepping in to decide. As early as this week, the federal government may adopt new rules for sharing water on the drought-stricken river. The Lower Basin states, which include California, are expected to face major cutbacks.

KJZZ reporter Alex Hager has been following the anticipated federal plan. He joined Midday Edition on Wednesday to discuss the impacts the new rules could have on cities like San Diego, which has long depended on the Colorado River but now has excess water to sell.

Extreme Heat and Dangerous Ocean Rip Currents About To Hit San Diego County

A large high-pressure system will move into San Diego County late Wednesday, triggering several days of extreme heat that will coincide with potentially deadly rip currents along the coast, the National Weather Service says.

Lifeguards are concerned because the ocean is 3 to 7 degrees warmer than normal, which will draw larger numbers of people into the water at a time when Hurricane Genevieve is sending big waves and strong rip currents to local beaches.

Heat Advisories Remain in Effect Until Tonight for San Diego County

Arant Was a ‘Water Titan’

Gary Arant, the longtime general manager of the Valley Center Municipal Water District, who died last week after several years of battling cancer, was, as his fellow industry members have described him, a “water titan”—but for Valley Center he was much, much more. 

He was a steady hand on the tiller during a 36-year period of unprecedented change. Which saw the transition of the water district from a largely agricultural water vendor, with a small tail of residential meters, to a dominantly domestic purchaser, with some farming sales.

San Diego’s Tiered Water Rate System Going Down the Drain. For Those Who Conserve, You’ll Be Paying More.

Most people who spend some time in San Diego understand that it’s a coastal desert city. “Desert” being the main word here. Because of this understanding, many adjust their behavior into conserving a desert’s most priceless commodity: water.

People take out their green grass and plant cacti and succulents; they don’t wash their car as much; they use less water in their normal day-to-day living and chores. And up to now, those residents who use less water were rewarded by a city of San Diego water rate system in which customers who use less water paid a lower rate, and those who use more water paid more.

How American Monsoon Will Impact Lake Powell, Mead Water Crisis in 2026

The North American monsoon could bring welcome rain to parts of the drought-hit Southwest this summer but forecasters and water specialists warn it is unlikely to meaningfully reverse the crisis gripping Lake Powell and Lake Mead.

The two reservoirs—the largest in the United States and critical storage points for the Colorado River—remain at severely depleted levels after years of drought, climate change-driven aridification and heavy demand from cities, farms and tribal communities across the West.

San Diego County Warming Trend Could Bring Heat Risk

Near seasonal temperatures are expected through the first half of the week in San Diego County, with an increase in both high and low temperatures for the middle to end of the week, the National Weather Service said Sunday.

An isolated shower or two may develop over the highest mountain peaks Sunday and Monday afternoon, with no impacts expected and drier conditions on Tuesday and Wednesday, the NWS said. There is an increased chance for afternoon or evening showers and thunderstorms over the mountains Thursday and Friday.

San Diegans Who Use Less Water Could See Their Monthly Water Bills Increase Next Year

San Diegans who use less water could see their monthly water bills increase in 2027 due to a proposed rate change that could eliminate the City’s tiered pricing system.

The proposal, prompted by a court ruling in Patz, et al. v. City of San Diego, 113 Cal. App. 5th 225 (2025), would replace the current tiered system, where customers who use less water pay a lower rate, and those who use more water pay more.

Bidding Farewell to a Keeper of Water Memory (scroll down)

When I was a budding water reporter at Voice, I knew – if I was confused, which I often was – I could call Gary Arant and he’d set me straight.

The former general manager of the Valley Center Municipal Water District stood out among the San Diego County Water Authority’s 34 board members because he wasn’t afraid to speak his mind – in a loveable, grouchy grandfather kind of way.

U.S. Provides Emergency Water to Tijuana After Pump Failure

The U.S. is providing emergency assistance to Tijuana after a pump failure reduced the city’s drinking water supply during peak summer temperatures.

Officials approved the delivery of about 368 acre-feet of Mexico’s share of Colorado River water through the U.S. conveyance system to help meet demand.
