The San Joaquin River, which helps
drain California’s Central Valley, has been negatively impacted
by construction of dams, inadequate streamflows and poor water
quality. Efforts are now underway to restore the river and
continue providing agricultural lands with vital irrigation,
among other water demands.
After an 18-year lawsuit to restore water flows to a 60-mile dry
stretch of river and to boost the dwindling salmon populations,
the San Joaquin River Restoration Settlement is underway.
Water releases are now used to restore the San Joaquin River and
to provide habitat for naturally-reproducing populations of
self-sustaining Chinook salmon and other fish in the San Joaquin
River. Long-term efforts also include measures to reduce or avoid
adverse water supply impacts from the restoration flows.
The Central Valley Regional Water Quality Control Board has
reported that a recent collection of water samples from
cyanobacteria harmful algal blooms along the Stockton
waterfront contain microcystins up to 220 times higher than the
“danger” level. These extremely dangerous readings were found
at 5 out of 6 testing sites along the Stockton waterfront.
Public health officials are urging boaters, swimmers and
recreational water users to be on the lookout for hazardous
blue-green algae blooms as warm temperatures persist. San
Joaquin County Environmental Health Department officials posted
advisory signs at local marinas warning people to stay out of
the water where toxic algae is present.
The San Francisco Estuary is a dynamic and altered estuary that
supports a high diversity of fishes, both native and
non-native. … Since the 1950s, various agencies and UC Davis
have established long-term surveys to track the status of fish
populations. These surveys help scientists understand how
fishes are responding to natural- and human-caused changes to
Water is the lifeblood of our region and there are immense
challenges to providing and maintaining a reliable and
resilient water supply for both farms and communities in the
Central Valley. As your congressional representatives, we’ve
been working together to bring resources back home to address
our collective needs.
As a result, the appellate decision, which upheld the central
role of the Delta Stewardship Council in Sacramento-San Joaquin
Delta water management and land use planning, remains intact
and is governing law.
At the July meeting of the Delta Stewardship Council,
councilmembers heard briefings on the activities of the Delta
Protection Commission and the Delta Conservancy, and an update
on the Central Valley Flood Protection Plan.
The Bureau of Reclamation announced Wednesday a 30-day public
comment period for a 35-year contract renewal of the transfer
of operation, maintenance and replacement activities related to
Friant-Kern Canal and other associated works to the Friant
Our newest video features our ongoing project to study the
non-native fishes of the San Joaquin River in California’s
Central Valley. Non-native fishes outnumber natives in the San
Joaquin, but we know surprisingly little about them…
Funding for much needed repairs at least in the short-term for
the Friant-Kern Canal continues to move closer to becoming
reality. The House of Representatives last week passed H.R.
7617… Included in that minibus is $71 million for repairs to
the Friant-Kern Canal during the next fiscal year.
The San Francisco Bay-Delta is among the most intensively
studied ecosystems in the world. Numerous long-term fisheries
monitoring programs have been conducted there since the late
1950s, but differences in the methods, scope, spatial coverage,
and timing of these surveys make it difficult to compare and
combine the data collected.
Saving our planet will require unprecedented focus and
investment from every sector of our society and all levels of
government — especially the federal government. Yet when it
comes to the San Francisco Bay — a national treasure and the
lifeblood of our region, producing over $370 billion in goods
and services annually and supporting more than 4 million jobs —
the federal government has been complicit in its deterioration.
Droughts are common in California. The drought of 2012-2016 had
no less precipitation and was no longer than previous
historical droughts, but came with record high temperatures and
low snowpack, which worsened many drought impacts.
At the July meeting of the Delta Stewardship Council, Delta
Lead Scientist Dr. John Callaway updated the Council on the
latest scientific developments, discussing three papers that
highlight the multi-faceted approach that is needed to address
the Delta’s ecosystem; he also previewed upcoming events and
provided the By the Numbers Report.
The Delta Plan Interagency Implementation Committee is
comprised of high-ranking members of 18 state, federal, and
regional agencies… At the July 2020 committee meeting,
members heard presentations on the Central Valley Project
Improvement Act and the state’s new Incidental Take Permit and
how those programs utilize principles of ecosystem-based
The California Central Valley Regional Water Quality Control
Board said lab results from July 14 revealed high levels of a
toxin called microcystins in scum samples from Mormon Slough,
the downtown marina and Morelli Park Boat Launch that ranged
from four to more than 20 times the state’s Tier 3 danger
The staff of the Federal Energy Regulatory Commission stated
its support once again for the fishery releases proposed by the
Modesto and Turlock irrigation districts. The action reaffirmed
FERC findings in February 2019 that dismissed pleas from
environmental and sport-fishing groups for much higher flows.
Feinstein’s Restoration of Essential Conveyance Act would
authorize $800 million in federal funding to repair critical
canals in the San Joaquin Valley damaged by land sinking from
overpumping of groundwater, known as subsidence, and for
In 2003, Congress passed The Nutria Eradication and Control
Act, which established a fund to help Maryland and Louisiana
battle the animals. Recently, the House of Representatives
passed bipartisan legislation that now allows California to
also receive support. The bill now heads to the Senate.
