As California enters the fourth consecutive extremely dry year and water availability is drastically limited, CDFW is taking a number of imperative actions to preserve and protect the state’s fish and wildlife resources. See the complete list of drought response efforts taking place throughout California.


CDFW has deployed staff to rescue threatened and endangered fish species on many rivers across the state. Staff also evacuated the American River and Nimbus hatcheries due to low flows making the water temperatures reach heights unsustainable for the fish there. We are actively monitoring conditions in waters around the state, including for steelhead and high country golden trout streams. We anticipate actions like these to continue as drought conditions persist. Please see below for information on fisheries-related actions.


Increased wildlife/human interaction has been reported and that may be due to drought conditions forcing wild animals to search father than normal for food. Black bear and mountain lion are considered the species of greatest concern for human interaction. CDFW is assessing its response resources (culvert traps for bears and darting equipment) throughout the state to better distribute these resources for timely response to incidents. Please see below for information on wildlife-related actions.


CDFW is heavily involved in operations to rid our state of illegal marijuana grows. The Governor’s 2014-15 budget bill provided an increase of $1.5 million to regulate and enforce unauthorized water diversions and pollution to surface and groundwater as a result of marijuana cultivation.

Marijuana plants use six to eight gallons of water per plant, per day, and are a direct hazard to wildlife that eats the plants. Even growers who have been authorized to cultivate marijuana in the state are often unaware of the need to get a permit from CDFW for diverting water from a stream. Please see below for information on marijuana-related actions.

Drought projects CEQA and Water Code suspension list:

On April 25, 2014, Governor Brown issued “A Proclamation of Continued State of Emergency,” an executive order that, among other things, directs CDFW to take certain actions to respond to drought conditions. The proclamation also suspends certain legal and regulatory requirements to allow actions to take place as quickly as possible.

Item 19 of the proclamation suspends environmental review required by the California Environmental Quality Act for the following projects being undertaken by CDFW:

  • Hill Slough Tidal Restoration Project
  • San Joaquin River Restoration Program Emergency Water Chillers
  • Honey Lake Wildlife Area pipeline and pivot irrigation
  • Ash Creek Wildlife Area dam replacement and pipeline installation
  • Ash Creek Wildlife Area restoration of Ash Creek
  • North Coast wildlife areas irrigation system replacement
  • Honey Lake Wildlife Area, Dakin Unit well replacement
  • Upper Butte Basin Wildlife Area well installation
  • Napa-Sonoma Marshes Wildlife Area recycled water system
  • Canebrake Ecological Reserve well refurbishment
  • Elkhorn Slough Ecological Reserve water catchment system
  • Rancho Jamul Ecological Reserve solar well installation
  • Rancho Jamul Ecological Reserve water delivery pipeline
  • Burcham Wheeler Ecological Reserve meadow restoration
  • Imperial Wildlife Area water delivery system enhancement
  • Shasta Valley Wildlife Area Water Diversion and Fish Screen Improvements

Item 20 of the proclamation suspends Chapter 3 of Part 3 (commencing with section 85225) of the Water Code for the following projects being undertaken by CDFW:

  • Hill Slough Tidal Restoration Project
  • Lindsey Slough Tidal Restoration Project

Item 26 of the Governor’s Executive Order No. B-29-15, dated April 1, 2015, suspends the California Environmental Quality Act as it applies to regulatory approvals necessary for the California Department of Water Resources (DWR) for its Emergency Drought Salinity Barrier Project.  CDFW has relied on this suspension in issuing Incidental Take Permit No. 2081-2014-026-03 and Lake and Streambed Alteration Agreement No. 1600-2014-0111-R3 to DWR.

Drought response projects

Since January 2014, the Department has conducted stream and species population monitoring, fish rescues, restoration projects and many other actions to protect native fish and wildlife threatened or impacted by the statewide drought. These reports reflect efforts at various locations along the coast, the Central Valley, mountains, and deserts of California.

Protecting our water resources

CDFW is taking great strides to keep as much water as possible in the rivers for fish and wildlife that depend on it. To that end, CDFW has introduced a voluntary drought initiative providing a framework for water users to enter into individual agreements with CDFW and NOAA Fisheries in an effort to maintain enough water for fish spawning in specific high priority streams, and implement other collaborative actions like fish rescue, relocation, monitoring and habitat restoration. In return, landowners and water users will benefit from greater regulatory certainty under the federal and state endangered species laws, and may receive incidental take authorizations for California Endangered Species Act (CESA)-listed fish in case a participant unintentionally takes listed fish species while withdrawing water.

Also, in March 2014, CDFW expedited approval for the installation of storage tanks by landowners who currently divert water from rivers and streams. Please see below for information on water-related actions.

Maximizing efficient use of water on CDFW lands

Based on the anticipated needs of migrating birds and other threatened and endangered wetland species throughout the state, CDFW is planning how best to allocate available surface and ground water, fully recognizing that domestic needs for water will take precedence if so determined. Any water that is available for wildlife habitat work will be distributed and used to benefit threatened/endangered species and maintenance of critical wetland habitats for vulnerable wetland-dependent species in the most efficient manner possible. Planning for this involves consideration of anticipated water availability for wildlife on all public and private lands and coordination with other agencies and stakeholders. Please see below for information on lands-related actions.

Water operations

CDFW, USFWS and the National Marine Fisheries Service (NMFS) have collectively worked to ensure that water management decisions do not unreasonably affect threatened and endangered species.

CDFW, in partnership with its federal agency counterparts, immediately began to increase monitoring of fish in the Sacramento River to better understand the drought’s impact on threatened species. This monitoring assesses spawning, rearing and stranding conditions, and it will closely track temperature conditions in the Sacramento River and its tributaries and the health of the winter run Chinook salmon species. DFW will also implement monitoring actions detailed in the Drought Operations Plan for Delta and long-fin smelt, green sturgeon and salmon and steelhead. Later this year, CDFW plans to work with NMFS and USFWS to complete restoration and fish passage projects for the benefit of several runs of salmon in the Upper Sacramento River and its tributaries.

Funding for drought response actions:

As part of the state's comprehensive drought response, CDFW has been funded to act on a wide variety of critical drought related fronts, including:

  • Habitat restoration in key areas of the Delta to support declining fish populations
  • Increased and enhanced monitoring of Central Valley salmon populations to inform targeted drought response actions
  • Additional habitat restoration and infrastructure improvements to support the San Joaquin River restoration program
  • Water conveyance and infrastructure improvements focusing on water efficiency on many of the state’s wildlife areas and ecological reserves
  • State-of-the-art monitoring of Delta fisheries to support real-time water management decisions
  • Infrastructure at many fish hatcheries to support short- and mid-term hatchery-based management fish removed from streams impacted by the drought
  • Additional targeted funding under the Fisheries Restoration Grant Program to deliver resources to partners poised to improve habitat in key spawning and cover areas
  • Increased funding for law enforcement to promote compliance with fish and wildlife protection laws in the context of drought stress to many fish and wildlife populations
  • For more information on current CDFW grant application opportunities for projects that sustain, restore and enhance California's fish, wildlife, plants and their habitats, see Grant Opportunities.

Governor Brown has called on all Californians to reduce their water use by 20 percent and prevent water waste – visit to find out how everyone can do their part, and visit to learn more about how California is dealing with the effects of the drought.

Quarterly progress reports

The 2014-15 state budget included $38 million for CDFW to respond to the effects of the California drought on fish and wildlife. Please link below to the progress reports recapping how projects are going and how the funds have been spent quarterly.
