The Otay Water District has launched its annual WaterSmart Landscape Contest as part of a continuing effort to encourage water conservation. Outdoor watering accounts for more than half of residential water use. The resident judged to have the most attractive, drought-toleranat garden receives a nursery gift card, among other prizes, and the title “Best in District.”
Following three consecutive years of drought in California, the Sierra Nevada snowpack is one of the most bountiful in more than 40 years. While the record snowpack and snow water equivalent is great news for water supply, there are concerns the record snowpack could create flooding issues.
California and Colorado are both receiving impressive amounts of snow.
That’s good for us because snow in the Rocky Mountains ultimately ends up in the Colorado River, which leads to Lake Mead.
That snow is hitting places like the Copper Mountain Ski Resort, which sits 9,700 feet up in Frisco, Colorado. That’s about an hour and a half west of Denver.
California’s unusually stormy winter is promising good news for the state’s struggling hydropower industry.
After three years of extreme drought, winter weather has driven up the most populous U.S. state’s snow levels to 235% of normal, according to the latest figures from the California Department of Water Resources. That’s likely to fill up hydro reservoirs during the spring melt, which could lead to more of the cheap renewable energy source and less dependence on fossil fuels, public agencies and utilities said.
The healthy snowpack whitening Colorado’s mountain peaks has given water officials some breathing room to manage the Colorado River Basin’s ongoing drought. The challenge will be not to squander it.
As winter storms wind down, water managers and policymakers are mulling over decisions about how to release and retain water in shrunken reservoirs across the basin, which supports 40 million people across the West.
Marty Plaskett upgraded his farming equipment and spent $60,000 on new sprinklers to conserve water, even before the rural Nevada valley where he farms alfalfa began more strictly managing groundwater.
Now, Plaskett is weighing another adjustment: selling off part of his legal right to use water that lies under his land to the state.
Nevada gets less than a 2 percent cut from the Colorado River’s waters, but the state actually uses far more water than that each year, all while staying well within its century-old legal water rights.
It’s all thanks to an extensive water recycling program in the Las Vegas Valley and something called “return flow credits,” which allow the state to pull extra water out of Lake Mead for every gallon of wastewater treated and returned to the reservoir via the Las Vegas Wash.
If you wanted to measure California’s change of water fortunes, the boat ramp at Lake Sonoma would be one place to do it.
The lake is the scene of an incredible four-month turnaround, for the very water system where the drought officially started.
“As you recall, three years ago, the governor literally was up at Lake Mendocino,” recalled Grant Davis with Sonoma Water. “Declaring the start of the drought basically, basically April 2021.”
The Otay Water District has launched its annual WaterSmart Landscape Contest as part of a continuing effort to encourage water conservation. Outdoor watering accounts for more than half of residential water use. The resident judged to have the most attractive, drought-toleranat garden receives a nursery gift card, among other prizes, and the title “Best in District.” The deadline to enter is Friday, May 12.
“This contest recognizes the outdoor conservation efforts our residential customers have made during a time when it matters most,” said Otay Water District Board President Mark Robak. “Previous winners of this program have proven that it is possible to create low-water and low-maintenance landscapes with curb appeal.”

The 2023 regional WaterSmart Landscape Makeover competition seeks the best in landscaping makeover projects from 12 participating San Diego County water agencies. The annual competition is intended to showcase residential water-saving landscaping projects. Winning examples help inform and inspire other homeowners to consider replacing their water-guzzling grass yards.
“We’re encouraged by the enthusiastic participation by San Diego County homeowners who are moving away from lawn-intensive landscaping as the default choice,” said Joni German, Water Resources Specialist with the San Diego County Water Authority. “Homeowners are creating lush, colorful, thriving landscapes which are water-efficient and beautiful at the same time.”

Following three consecutive years of drought in California, the Sierra Nevada snowpack is one of the most bountiful in more than 40 years. While the snowpack and snow water equivalent is great news for water supply, there are concerns the record snowpack could create flooding issues.
The California Department of Water Resources electronic readings from 130 snow sensors placed throughout the state indicate the statewide Sierra Nevada snowpack’s snow water equivalent is 61.1 inches, or 237% of average for April 3. The snow water equivalent measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast.

This year’s April result from the statewide snow sensor network is higher than any other reading since the snow sensor network was established in the mid-1980s. Before the network was established, the 1983 April 1 statewide summary from manual snow course measurements was 227% of average. The 1952 April 1 statewide summary for snow course measurements was 237% of average.

“This year’s severe storms and flooding is the latest example that California’s climate is becoming more extreme,” said DWR Director Karla Nemeth. “After the driest three years on record and devastating drought impacts to communities across the state, DWR has rapidly shifted to flood response and forecasting for the upcoming snowmelt. We have provided flood assistance to many communities who just a few months ago were facing severe drought impacts.”
Just as the drought years demonstrated that California’s water system is facing new climate challenges, this year is showing how the state’s flood infrastructure will continue to face climate-driven challenges for moving and storing as much of these flood water as possible.
“This year’s result will go down as one of the largest snowpack years on record in California,” said Sean de Guzman, manager of DWR’s Snow Surveys and Water Supply Forecasting Unit.

“This year’s result will go down as one of the largest snowpack years on record in California,” said Sean de Guzman, manager of DWR’s Snow Surveys and Water Supply Forecasting Unit. “While 1952’s snow course measurements showed a similar result, there were fewer snow courses at that time, making it difficult to compare to today’s results. Because additional snow courses were added over the years, it is difficult to compare results accurately across the decades with precision, but this year’s snowpack is definitely one of the biggest the state has seen since the 1950s.”

For California’s snow course measurements, only 1952, 1969 and 1983 recorded statewide results above 200% of the April 1 average. While above average across the state this year, snowpack varies considerably by region. The Southern Sierra snowpack is currently 300% of its April 1 average and the Central Sierra is at 237% of its April 1 average. However, the critical Northern Sierra, where the state’s largest surface water reservoirs are located, is at 192% of its April 1 average.
The size and distribution of this year’s snowpack is also posing severe flood risk to areas of the state, especially the Southern San Joaquin Valley. DWR’s State-Federal Flood Operations Center (FOC) is supporting emergency response in the Tulare Lake Basin and Lower San Joaquin River by providing flood fight specialists to support ongoing flood response activities and by providing longer-term advanced planning activities.
The FOC and DWR’s Snow Surveys and Water Supply Forecasting Unit are helping local agencies plan for the spring snowmelt season by providing hydraulic and hydrologic modeling and snowmelt forecasts specific to the Tulare Lake Basin that are informed by DWR’s snowmelt forecasting tools, including Airborne Snow Observatory (ASO) surveys.

Storms this year have caused impacts across the state including flooding in the community of Pajaro and communities in Sacramento, Tulare, and Merced counties. The FOC has helped Californians by providing over 1.4 million sandbags, over 1 million square feet of plastic sheeting, and over 9,000 feet of reinforcing muscle wall, across the state since January.
On March 24, DWR announced an increase in the forecasted State Water Project deliveries to 75%, up from 35% announced in February, due to the improvement in the state’s water supplies. Governor Gavin Newsom has rolled back some drought emergency provisions that are no longer needed due to improved water conditions, while maintaining other measures that continue building up long-term water resilience and that support regions and communities still facing water supply challenges.
While winter storms have helped the snowpack and reservoirs, groundwater basins are much slower to recover. Many rural areas are still experiencing water supply challenges, especially communities that rely on groundwater supplies which have been depleted due to prolonged drought.
Long-term drought conditions in the Colorado River Basin will also continue to impact the water supply for millions of Californians. The state continues to encourage Californians to make water conservation a way of life as more swings between wet and dry conditions will continue in the future. The San Diego County Water Authority and its 24 member agencies provide rebates and programs to encourage water conservation.
Given the size of this year’s snowpack with more snow in the forecast, DWR anticipates conducting a May snow survey at Phillips Station. That is tentatively scheduled for May 1.
