OPINION: Block Outrageous Effort To Lock In Delta Tunnels Water Grab

/in , /by /The Mercury News (San Jose)

Gov. Jerry Brown’s administration is now trying to jam through a political deal that would enable construction of his $17 billion Delta twin-tunnels project, the biggest public works project in state history, without the approval of the state Legislature, the voters or ratepayers who would be footing the bill. Brown’s state Department of Water Resources suddenly plans to extend State Water Project contracts, with amendments, for another 50 years. Fifty years! That would allow water contractors backing the twin-tunnels project to lock in water contracts for the Delta tunnels project before Brown leaves office at the end of this year.

SANDAG Will Preserve Nearly 112 Acres Of Habitat In Carmel Valley

/in , /by /Del Mar Times

SANDAG recently acquired nearly 112 acres of native habitat and old agricultural lands in Carmel Valley, according to a news release. The old agricultural lands will be restored to wetland habitat and the remaining land will be preserved as open space. The land, referred to as Deer Canyon East, is immediately adjacent to and upstream of the 31-acre Deer Canyon West wetland mitigation site. The acquisition was finalized this June shortly after the West property was deemed successfully restored by federal and state agencies.

When It Comes To Lawns, Use it or Lose It

/in , /by

If you have a desire and a need to retain turf as part of your landscaping, consider adopting the most efficient and organic maintenance plan possible. Lawns that are maintained organically and with efficient irrigation can offer a cool, practical surface for active recreation, or just hanging out with your family.  

Most lawns suffer from inefficient maintenance. They require too much water and energy. They become major sources of pollution from fertilizers and pesticide runoff. For these reasons, lawns should be limited to accessible, usable, high-functioning spaces like children’s play yards, sports fields, and picnicking areas. 

It’s smart to rethink the idea of lawns as all-purpose, wall-to-wall groundcover. In many cases, there is no need to maintain so much lawn. If you decide to keep your grass areas, follow these guidelines to maintain it organically.

  • Apply a thin layer of compost annually. 
  • Aerate and de-thatch your lawn annually. 
  • Manage your irrigation carefully. Control overspray and fix problems promptly. 
  • Mow less frequently. Maintain 3 to 4 inches of height on cool season grass, and 1.5 to 2 inches of height on warm season grass.  
  • Grass-cycle every time you mow. 
  • Don’t allow seed heads to form on the grass, and remove those that do form. 
  • Consider over-seeding with clover to help make the grass more interesting looking and more drought-tolerant. 
  • Eliminate chemical inputs to your grass. 

What’s the difference between Cool Season Grass and Warm Season Grass? 

Cool Season Grass: 

  • Needs more water than warm season grass and is considered a high use plant. 
  • Requires watering in hot summers to prevent it from going dormant and turning brown 
  • Grows typically as bunch grasses and propagates by seed or weak stolons. 
  • Cool season grass is easily smothered by sheet mulching.
  • Varieties include: Bent Grass (Agrostis), Fescue varieties (Festuca), Kentucky Bluegress (Poa pratensis), Perennial Ryegrass (Lolium perenne) 

Warm Season Grass: 

  • Is a moderate water use plant. 
  • Peaks when temperatures exceed 80 degrees, but it will go dormant (brown) in winter months when it is rainy and cool. 
  • Grows from sturdy rhizomes extending deep underground. Warm season grasses require physical removal and/or extensive sheet mulching (up to 12 inches).
  • Varieties inclue: Bermuda Grass (Cynodon dactylan), Blue Grama (Bouteloua gracilis), Buffalo Grass (Buchloe actyloides), St. Augustine Grass (Stenotaphrum secundatum), Zoysia, and Seashore Paspalum.

Delta Breezes Are Dying And That Could Be Bad News For An Imperiled Fish

/in , /by /Water Deeply (New York)by Tom Philp

As a 27-year Sacramentan, it’s pretty easy to detect that there are fewer winter moments of dense, bone-penetrating valley fog than before. Winter used to mean days on end without seeing a sun in the sky. But how many of us are just as aware that the blessed Delta breeze also isn’t what it used to be? (It sure abandoned us in July.) Or how this ebbing of the wind has shifted the ecology of the Sacramento-San Joaquin Delta itself?

Fire Officials To Trump: No, California Didn’t Worsen Wildfires By Dumping Water Into Ocean

/in , /by /The Washington Postby Kristine Phillips

As fires grow to historic sizes in California, President Trump tweeted that the state is “foolishly” diverting “vast amounts of water from the North” into the Pacific Ocean instead of using them to fight its wildfires. The state’s “bad environmental laws” are to blame, he added. The tweets baffled state officials, who quickly pointed out that water supplies are not the problem. “Let’s be clear: It’s our changing climate that is leading to more severe and destructive fires,” said Cal Fire spokesman Mike Mohler. Scott McLean, also a Cal Fire spokesman, said he doesn’t understand the president’s comments.

As Storms Worsen, America’s Aging Dams Overflow

/in , /by /CBS Newsby Ed Leefeldt

More than 80,000 people in the mountain community of Lynchburg, Virginia, were at risk, and 120 families evacuated, when rising waters from nearby College Lake reecently threatened to overflow its outdated dam. Although calamity was averted when the water receded, the incident was a frightening reminder of the growing risk facing millions of Americans. The average age of the 90,580 dams located across the U.S is 56 years, according to the American Society of Civil Engineers (ASCE). Worryingly, more than 15,000 of them are considered “high hazard” and – like the Lynchburg dam built in the 1930s – need to be repaired or replaced.

Ventura County Supervisors Urge Casitas To Make Drought Declaration As Lake Levels Fall

/in , /by /Ventura County Starby Kathleen Wilson

The Ventura County Board of Supervisors on Tuesday urged a water district serving more than 60,000 people and hundreds of farms to declare a drought emergency. Supervisor Steve Bennett said the declaration should be made promptly to warn residents about the seriousness of the situation in the western Ventura County area served by the Casitas Municipal Water District. “It is critical that those who rely on (the district’s) water realize the dire nature of this drought and have the opportunity to take any steps they possibly can to conserve further and stretch the length of time water is available,” Bennett wrote in a letter to the board.

Efficiencies Lower Long-Term Water Demand Forecast for San Diego Region

/in , /by by Water News Network Staff

Updated water-use projections for the San Diego region through 2040 are substantially lower than earlier forecasts due to efficiencies that have become standard practice at homes and businesses countywide.

That’s good news because it signals the potential for lower spending on water supply development and delivery in coming decades compared to previous forecasts.

The revised demand forecast by the San Diego County Water Authority also highlights how the region continues to align with state mandates for water-use efficiency even after nearly three decades of significant savings. Per capita potable water use in the Water Authority’s service area declined nearly 50 percent between fiscal years 1990 and 2017.

Changing Water-Use Habits Prompt ‘Reset’

Revisions to the region’s water demand forecast were designed to align the Water Authority’s planning document with current water-use trends. Through the Urban Water Management Plan, the agency updates demand forecasts every five years, with the next comprehensive update in 2020.

However, emergency state regulations related to the 2012-2016 drought combined with the ongoing transformation of the landscaping market toward low-water-use designs and other factors significantly lowered water use between the formal five-year planning periods. That change prompted the interim demand “reset” by the region’s water wholesaler.

Instead of projecting 588,000 acre-feet of demand in 2020, the Water Authority now anticipates demand will be at 537,000 acre-feet – a reduction of approximately 9 percent. Projections through 2040 follow suit, so that annual demand is projected to be 655,000 acre-feet at the far end of the Water Authority’s planning horizon instead of 719,000 acre-feet.

“We wanted the forecast to reflect current conditions and demand levels, and we also wanted to have an inclusive process for receiving input from our member agencies,” said Tim Bombardier, principal water resources specialist for the Water Authority. “The net effect is that the interim demand forecast reset shifts the entire line down by about 60,000 acre-feet for the entire 2020 to 2040 planning horizon.”

The demand reset is intended as a provisional update, and a comprehensive update of the forecast will coincide with preparation of the Water Authority’s 2020 Urban Water Management Plan. Decreased demands change the amount of supplies necessary in future years, an issue the Water Authority will assess in detail when developing the 2020 plan. That process will start in late 2018.
