Projects Create Wetlands, Improve Water Quality in San Diego Region

Since 2005, the San Diego Integrated Regional Water Management Program has supported and funded water conservation, water quality and resource projects throughout San Diego County.

Program partners, including staff of the San Diego County Water Authority and its 24 member agencies, the California Department of Water Resources, and regional water industry leaders, met at the Water Conservation Garden at Cuyamaca College Monday to celebrate 15 years of achievements.

The program facilitates collaboration on water resources planning and projects in the region by water retailers, wastewater agencies, stormwater and flood managers, watershed groups, the business community, tribes, agriculture, and nonprofit stakeholders.

CWA Approves Shutdown Schedule for Pipeline 5 Work at Moosa Creek

In 2019, the San Diego County Water Authority repaired a leak to a pipeline in Moosa Canyon. That repair was followed by an assessment of the other two SDCWA pipelines in the area, and one of those was found to be at risk so the CWA will be making repairs to that pipeline.

A CWA board vote, Feb. 27, authorized CWA general manager Sandra Kerl to take the necessary contracting and other actions for the repairs on Pipeline 5 in Moosa Creek. The current schedule includes shutdowns March 30 through April 5 for the installation of isolation bulkheads and May 18 to May 24 for the removal of the bulkheads as well as carbon fiber lining work expected April 6 through May 15.

May 24 is the Sunday of Memorial Day weekend, and the actual shutdown schedule will likely be revised as the repair work progresses.

California Wants Feds to Address Cross-Border Sewage

State water pollution regulators in San Diego are asking federal officials to do more monitoring of cross-border water flows that could be polluted.

The San Diego Regional Water Quality Control Board issued an investigative order in February that requires more monitoring of sewage-tainted cross-border flows.

The order requires the International Boundary and Water Commission to monitor more than a dozen locations over an 18-month period.

Regional Board Executive Director David Gibson said the order also calls for the testing results to be made public.

Study: Water Restrictions to Mean Billions in Lost Farm Revenue

A new study by University of California researchers anticipates drastic economic losses in the face of future restrictions on water available for San Joaquin Valley agriculture.

The study by economists David Sunding and David Roland-Holst at UC Berkeley examined the economic impact of two types of restrictions to water supplies for ag: on groundwater pumping as part of the Sustainable Groundwater Management Act and future reductions in surface water due to regulatory processes by the state and federal government.

Up to one million acres of farmland could be fallowed over the next 20 to 30 years — about one-fifth of all acres currently under cultivation in the San Joaquin Valley. Associated farm revenue loss would be about $7.2 billion a year.

Seepage Monitors Installed at Oroville Dam

This week, the California Department of Water Resources (DWR) will install eight new measurement devices at the base of the Oroville Dam. The devices, called piezometers will monitor seepage and will be used to confirm seepage measurements that the DWR already collects. Seepage refers to a small amount of water that can pass through the dam.

DWR said seepage is normal and expected, especially in large, earthen dams like Oroville. Seepage is measured and collected through a drainage system.

There were 56 piezometers originally installed in the dam fifty years ago which, as anticipated, have since stopped functioning. DWR plans to install additional piezometers throughout the facility in the coming years.

San Diego County’s War Over Roundup

It’s everywhere, taking over like the weeds it’s meant to kill. Now glyphosate, the bestselling weedbuster of all time, has become a pest.

“Everybody in this room has glyphosate and other components in Roundup in their body,” said Dave Schubert, a researcher at Salk Institute who spoke in favor of a ban last week that supervisors have proposed for the unincorporated county.

Around the country, tens of thousands of lawsuits target glyphosate-based herbicides which homeowners, groundskeepers and others say caused their cancer. Heavy use of the chemical in agriculture has promoted superweeds, and is suspected of harming pollinators like honeybees.
