This report prepared by the Bureau of Reclamation and the US Fish and Wildlife Service in December 2008 analyzes the Central Valley Project Improvement Act (CVPIA) and its impacts on increasing the populations of anadromous fish in Central Valley rivers and streams. The CVPIA (1992) had a goal of doubling the population by 2002, which didn't happen. The report claims that this goal will not be achieved unless renewed commitments and improvements are made to the program.

This US Fish and Wildlife Service filed a report with FERC on the economic value of refuge based recreation across the nation, on Dec 6, 2007. The main objective of the study was to estimate the national impact of refuges on their regional and local economies. This report studied 80 sample refuges (of a total of 548) and presented findings on:

1. Visitor Recreation-Related Expenditures

2. Economic Effects Associated With Refuge Visitation, and

3. Summary of Economic Effects of Refuge Visitation.

Summary findings:

1. In 2006, 34.8 million people visited wildlife refuges resulting in $1.7 billion in sales and $185 million in tax revenues.

2. Activities related to refuge visitation resulted in employment for 27,000 people

It concludes that recreational visits to national refuges generate substantial economic activity.
