It’s Time for States to Invest in Infrastructure

Center on Budget and Policy Priorities | August 10th, 2017

State investment in transportation, public buildings, water treatment systems, and other forms of vital infrastructure is key to creating good jobs and promoting

State investment in transportation, public buildings, water treatment systems, and other forms of vital infrastructure is key to creating good jobs and promoting full economic recovery. States should reject the flawed economic growth strategy of cutting taxes and offering corporate giveaways, and instead identify and make investments in infrastructure that provide the foundation for a strong economy. It’s a good time for states to make those investments.

Joining Forces: Innovative Co-Funding to Enhance Corporate Water Stewardship Impact in the Colorado River Basin

Pacific Institute | May 16th, 2023

The premise of this paper is that co-funding with existing and emerging funding mechanisms can help corporations tackle more complex problems at more meaningful scales in the Colorado River Basin and beyond. Corporations often have more flexibility than other funders, particularly federal and state agencies, in deciding how to spend their water stewardship budgets. This flexibility is an important asset, allowing funding to be deployed strategically. This white paper defines innovative co-funding as the intentional and focused use of corporate water stewardship funding alongside other funders and funding sources in new ways that expand the impact of corporate spending.

Juvenile Production Estimate (JPE) Calculation and Use/Application of Survival Data from Acoustically-tagged Chinook Salmon Releases Report

Delta Stewardship Council (Delta Council) | February 21st, 2014

Each year, NOAA’s National Marine Fisheries Service (NMFS) estimates the number of juvenile winter-run Chinook salmon expected to enter the Delta. NMFS’ June 4, 2009

Each year, NOAA’s National Marine Fisheries Service (NMFS) estimates the number of juvenile winter-run Chinook salmon expected to enter the Delta. NMFS’ June 4, 2009, biological and conference opinion on the long-term operation of the Central Valley Project and State Water Project provides an incidental take limit on natural juvenile winter-run based on the juvenile production estimate.

Juvenile salmonids traverse coastal meta-nurseries that connect rivers via the sea

Conventionally, juvenile salmonids are thought to migrate unidirectionally from freshwater systems to marine systems and therefore only inhabit natal drainages. Although scattered evidence suggests juveniles can move bidirectionally between freshwater rivers and the ocean, including into non-natal drainages, such movements have never been documented with high replication. Here, we detected hundreds of movements of juvenile salmonids between drainages that involved 0–22% of cohort emigrants in Washington State and California. Individuals moved up to nine times and between drainages up to 70 km apart. These findings reveal a life-history type of salmonids whose remarkably complex migrations have gone unnoticed. Implicitly, juveniles may use any coastal freshwater habitat accessible from the sea and may not descend from spawning populations of drainages they inhabit. Consequently, typical conservation focused on natal drainages may overlook freshwater habitat elsewhere. A concept of coastal areas as meta-nurseries formed by multiple watersheds connected by the sea may accurately describe anadromous species’ habitat options and better inform management.

Kaweah Subbasin Probationary Hearing Draft Staff Report

California State Water Resources Control Board (SWRCB) | May 2nd, 2024

The State Water Board recognizes that local public agencies in the Kaweah Subbasin have made significant efforts since the passage of SGMA to form three groundwater sustainability agencies (GSAs) and then develop detailed technical and other information supporting the adoption and implementation of three groundwater sustainability plans (GSPs) for the subbasin. Despite those efforts, in January of 2020, DWR reviewed the three GSPs to determine if the GSPs met SGMA’s requirements and found the GSPs to be incomplete. Following revisions made by the GSAs in the subbasin, DWR reevaluated the GSPs in March of 2023, determined the GSPs to be inadequate, and referred the subbasin to the State Water Board, as required by SGMA. Consistent with SGMA, the State Water Board may now consider whether to designate the Kaweah Subbasin as a “probationary basin,” a term that is used in SGMA to describe a basin in the first stage of state intervention.  Click here for Water Board updates on hearings. A January 5, 2025 has been cancelled to allow more time to review updated groundwater sustainability plans.
