Executive Order S-17-06, directed us to “develop a durable vision for sustainable management of the Delta” with the goal of “...managing the Delta over the long term to restore and maintain identified functions and values that are determined to be important to the environmental quality of the Delta and the economic and social well being of the people of the state.” The executive order calls for our vision to be completed by January 1, 2008 and a strategic plan by November 2008.

Over‐pumping leads to California groundwater arsenic threat

Water resources are being challenged to meet domestic, agricultural, and industrial needs. To complement finite surface water supplies that are being stressed by changes in precipitation and increased demand, groundwater is increasingly being used. Sustaining groundwater use requires considering both water quantity and quality. A unique challenge for groundwater use, as compared with surface water, is the presence of naturally occurring contaminants within aquifer sediments, which can enter the water supply. Here we find that recent groundwater pumping, observed through land subsidence, results in an increase in aquifer arsenic concentrations in the San Joaquin Valley of California. By comparison, historic groundwater pumping shows no link to current groundwater arsenic concentrations. Our results support the premise that arsenic can reside within pore water of clay strata within aquifers and is released due to overpumping. We provide a quantitative model for using subsidence as an indicator of arsenic concentrations correlated with groundwater pumping.

Pared-Down Water Plan to Be Submitted in 1987

SACRAMENTO — Gov. George Deukmejian’s Administration is preparing to submit a new water package to the Legislature in 1987, a stripped-down version of the plan that failed in 1984, according to David N. Kennedy, director of the state Department of Water Resources. The plan, contingent on Deukmejian’s reelection next year, would reverse the position the governor took after the stinging rebuke of a year ago, when he blamed Democratic lawmakers for the defeat. He said then that it would be up to the Legislature to produce an acceptable plan for supplying the state’s water needs. But now the Administration is once again gearing up to take the initiative on the water issue. The package would contain three key elements: - Authorization for $300 million in Sacramento-San Joaquin Delta projects needed to ship additional surplus water south. - A commitment to help maintain and restore deteriorating delta levees. - Environmental protections for San Francisco Bay.

The importance of the natural flow regime to stream and river health has received growing attention over the last two decades. Quantifying natural river flows has become an essential component of water resource planning, including assessments of water supplies (Vicuna,Maurer, Joyce, Dracup, & Purkey, 2007; Wurbs, 2005), reservoir operations (Hejazi, Cai, & Ruddell, 2008) and drought risk (Meko,Therrell, Baisan, & Hughes, 2001). Understanding the natural flow regime is also crucial for managing stream ecosystems.
