Planning For A Drier Future In The Colorado River Basin

/in , /by /Public Policy Institute of California (San Francisco, Calif.)by Lori Pottinger

The Colorado River has experienced decades of over-allocation of its waters, making it harder to address the added challenges that climate change is bringing. The recently adopted Drought Contingency Plan (DCP) was an important step toward addressing the basin’s chronic water shortages, but more work is needed to prepare for a hotter, drier future. We talked to Doug Kenney—director of the Western Water Policy Program at the University of Colorado and a member of the PPIC Water Policy Center research network―about managing the basin for long-term water sustainability. Kenney organized a conference in June that covered these issues in depth.

San Diego’s Water Portfolio Approach ‘Model for California’

/in , /by

State officials Thursday toured San Diego County water infrastructure to get a first-hand look at the region’s successful water portfolio approach for supply diversification.

California Natural Resources Agency Secretary Wade Crowfoot, Deputy Natural Resources Secretary Thomas Gibson, State Department of Food and Agriculture Secretary Karen Ross, and State Water Resources Board Chair E. Joaquin Esquivel were here to assess the region’s water projects as part of their new role in developing a water portfolio strategy for the state.

Portfolio approach benefits region

“The region is proof that the portfolio approach works,” said Water Authority Board Chair Jim Madaffer. “The Water Authority and its 24 member agencies continue to develop local projects and explore opportunities that would benefit the region, the state, Mexico and the Southwest.”

At a luncheon meeting and panel discussion at University of California, San Diego following the tour, the agency officials joined a group of more than 150 people to hear how the portfolio approach can help California and the Southwest meet water supply challenges.

Along with the Water Authority Board of Directors, elected officials, business, community and state and local leaders gathered in an auditorium at the Southwest Fisheries Science Center on the La Jolla campus.

Jim Madaffer and Water Portfolio approach

“The state needs to look at a global approach to managing water,” said Water Authority Board Chair Jim Madaffer.

Madaffer said during the meeting that San Diego’s portfolio approach has been successful in increasing the region’s water supply reliability through diversification and innovation.

“The Water Authority’s model is one that can be replicated across the state to help ensure a secure water future for all Californians,” said Madaffer.

State agency leaders echoed Madaffer’s comments.

“San Diego has been a leader in the water portfolio approach,” said Wade Crowfoot. “We have to make the investments to build regional water resilience as part of the Governor’s order to develop a portfolio to manage water in California.”

Water resilience portfolio for 21st century 

The Water Authority invited the officials to visit after Gov. Gavin Newsom issued an Executive Order in April, directing state agencies to “prepare a water resilience portfolio that meets the needs of California’s communities and environment through the 21st century.”

In his May letter to Newsom, Madaffer thanked the governor for the “wisdom and leadership” with the issuance of Executive Order N-10-19, and invited the governor to tour San Diego County’s cutting-edge water facilities.

Newsom’s order also directed his administration to “identify and assess a suite of complementary actions to ensure safe and resilient water supplies, flood protection and healthy waterways for the state’s communities, economy and environment.”

The California Natural Resources Agency, the California EPA, and the California Department of Food and Agriculture, in consultation with the Department of Finance, were directed by Gov. Newsom to, among other tasks, “identify key priorities for the administration’s water portfolio moving forward.”

“Governor Newsom wants us to think long and broadly on water,” said Crowfoot. “He wants us to get away from the silos and conflicts on water in California – the mindset of environment groups versus farmers, north versus south, urban versus rural – and work together on water resiliency.”

Significant investments in regional water strategy

“The Water Authority and its 24 member agencies have made significant investments in the last two decades to diversify our water supply, creating a portfolio of resources to support our region’s 3.3 million people and $231 billion economy,” said Madaffer.

During the tour, the officials got a first-hand look at some of those investments, including the San Vicente Reservoir, Olivenhain Reservoir, and the Claude “Bud” Lewis Carlsbad Desalination Plant.

Global Warming creates water supply challenges

Scripps Institution of Oceanography research meteorologist Dan Cayan told the audience that temperatures and dry spells will increase in California in the future, making water storage, conservation, and forecasts even more critical.

“Global warming climate models show the Sierra Nevada snow pack will be 50% less in 2090 than today’s average April 1 snowpack,” said Cayan.

Cayan said observations and climate model projections indicate climate change is occurring and will grow stronger. California should expect 1.5-2 degrees Fahrenheit warming by 2050, he said.

New regional pipeline study

Water Authority Assistant General Manager Dan Denham described a new study that will explore the viability of a regional pipeline to transfer water from the Colorado River to benefit multiple users in San Diego County and across the Southwest.

The pipeline system is one of a handful of ideas being discussed by San Diego County water leaders to enhance partnerships and solutions that make sense locally and more broadly as part of Governor Newsom’s Water Portfolio Program to develop resiliency statewide.

Two of the routes (the light blue and purple lines) follow a southern route. The third proposed route, (shown in both a yellow and darker blue line) follows a northern path. Graphic: Water Authority

Creating a pipeline to transfer Colorado River water to the San Diego region has been studied periodically over decades.

But the new study is focused on how a regional pipeline could provide multiple benefits as part of a long-term water management strategy for California and the Southwest.

The expanded review will consider a system that could create much-needed storage opportunities for the Imperial Irrigation District that could support agriculture while addressing critical issues like the Salton Sea and the need for more renewable energy development.

We haven’t published many ten-part editorials in the Daily Post over the past 15 years. But we also don’t come across many political issues — local, state, or national — as complicated or as perplexing as the declining lake levels in the two largest reservoirs situated on the Colorado River: Lake Mead and Lake Powell.

Study to Assess Regional Pipeline for Delivering Colorado River Water

/in , /by

A new study will explore the viability of a regional pipeline to transfer water from the Colorado River to benefit multiple users in San Diego County and across the Southwest.

The San Diego County Water Authority’s Board of Directors approved funds for the two-year study at its June 27 Board meeting. The pipeline system is one of a handful of ideas being discussed by San Diego County water leaders to enhance partnerships and solutions that make sense locally and more broadly as part of Governor Newsom’s Water Portfolio Program to develop resiliency statewide.

Regional pipeline

The Water Authority’s upcoming study will look at a regional conveyance system that could move Quantification Settlement Agreement (QSA) transfer water directly between the Imperial Valley and San Diego. The Colorado River Aqueduct currently conveys the QSA water through Riverside County before it flows to San Diego.

“It may be an idea whose time has come,” said Erik Ortega, president of the Imperial Irrigation District Board of Directors, referring to a proposed regional conveyance system.

Creating a pipeline to transfer Colorado River water to the San Diego region has been studied periodically over decades.

But the new study is focused on how a regional pipeline could provide multiple benefits as part of a long-term water management strategy for California and the Southwest.

Water storage

The expanded review will consider a system that could create much-needed storage opportunities for the IID that could support agriculture while addressing critical issues like the Salton Sea and the need for more renewable energy development.

Three pipeline routes

The pipeline under study would be designed at a capacity to convey the QSA water, which in 2021 will reach its full amount of 280,000 acre-feet of water annually. The current Water Transfer Agreement between IID and the Water Authority continues to 2047. But both agencies can agree to extend the transfer another 30 years to 2077.

As the study gets under way, there are three routes under consideration. Each of those routes would connect to the tail end of the All-American Canal where it meets the Westside Main Canal in the southwest corner of the Imperial Valley.

Two of the routes would follow a southern corridor between the Imperial Valley and San Diego, with one route over the mountains paralleling the U.S./Mexico border and the other tunneling underneath the mountains. Both routes would lead to the San Vicente Reservoir in San Diego.

The third and northernmost route would follow the Westside Main Canal toward the Salton Sea, then flow past Borrego Springs, and through the mountains. It would eventually connect to the Water Authority’s Twin Oaks Valley Water Treatment Plant in San Marcos.

Lower Colorado River Basin Can Still Expect Shortage Next Year

/in , , /by /KJZZby Bret Jaspers

The Lower Colorado River Basin does not avoid a shortage in 2020 despite the plentiful snowpack on the Rocky Mountains this past winter. Why? Well, the new Drought Contingency Plan defines different “tiers” of shortage. The Lower Basin will not drop into a Tier One shortage next year because Lake Mead will almost certainly remain above 1,075 feet in elevation.  At the same time, Mead will likely remain under 1,090 feet. That triggers a Tier Zero shortage.

A sweeping deal to plan for drought in the Colorado River Basin may yet include the river’s largest water user. The Imperial Irrigation District was frozen out of the multi-state deal when Los Angeles water managers offered to provide water cutbacks if Lake Mead continues to lose water. However, the Southern California water district still hopes to join the federal drought contingency plan.

OPINION: San Diego Is Ready For Some Big Water Solutions

/in , /by /San Diego Union-Tribuneby Jim Madaffer

Back in the early 1990s — near the start of my career at San Diego City Hall — the San Diego County Water Authority launched a historic effort to sustain the region’s economy and quality of life by diversifying our water supplies so that we didn’t depend on one source for 95 percent of our water. That effort took many forms, many billions of dollars and more than two decades — but it paid off in spades. Even though we are at the literal end of the pipeline, today we have among the most diversified and secure water supply systems anywhere.

New Project Takes Aim At Controlling Salton Sea Dust

/in , /by /KPBSby Erik Anderson

As the water pulls back from long-time shorelines along California’s Salton Sea, officials are working to keep dust from the exposed lake bottom out of the air. Bruce Wilcox of the California Resources Agency looked out at what is now the new normal on the 35-mile-long lake’s southeastern shore. “Fifteen years ago there was water right where we’re standing and it’s just receded that much,” Wilcox said as he stood on a spur of land that used to be part of a boat launch.

Federal Register Notice On DCP Draws Ire From IID

/in , /by /Imperial Valley Pressby Tom Bodus

A notice published recently in the Federal Register is not sitting well with Imperial Irrigation District. That notice, submitted by the Department of Interior through the Bureau of Reclamation and published on Feb. 1, calls recommendations from the governors of the seven Colorado River Basin state for protective actions the Department of Interior should take in the absence of a completed drought contingency plan. Bureau of Reclamation Commissioner Brenda Burman set a deadline of Jan. 31 for states to complete and approve a DCP.

There is a massive deadline looming for states that draw water from the Colorado River Basin — Arizona included. If an agreement on water use and conservation isn’t reached by Jan. 31, the federal government can step in and begin to make conservation decisions for the states. We’ve covered this story extensively on The Show with KJZZ’s Bret Jaspers, but now, there is another twist in it — this time out of California.
