VAMP - Vernalis Adaptive Management Program
| VAMP, officially initiated in 2000 as part of the State Water Resources
Control Board (SWRCB) Decision 1641, is a large-scale, long-term (12-year),
experimental/management program designed to protect juvenile Chinook
salmon migrating from the San Joaquin River through the Sacramento-San
Joaquin Delta. VAMP is also a scientifically recognized experiment to
determine how salmon survival rates change in response to alterations
in San Joaquin River flows and State Water Project (SWP)/Central Valley
Project (CVP) exports with the installation of the Head of Old River
Barrier (HORB). VAMP employs an adaptive management strategy to use
current knowledge of hydrology and environmental conditions to protect
Chinook salmon smolts, while gathering information to allow more efficient
protection in the future.
The 2010 San Joaquin River Group Authority Annual Technical Report (PDF - 13.27 MB) is comprised of the consolidated annual San Joaquin River Agreement (SJRA) Operations Report and Vernalis Adaptive Management Plan (VAMP) Monitoring Report. The VAMP program has demonstrated the value of large-scale, long-duration, interdisciplinary experimental investigations that provide both protection to fishery resources while also providing important information that can be used to evaluate the performance and biological benefits of various management actions. The VAMP program has also demonstrated the value of an interdisciplinary approach, integrating fisheries and hydrology adaptively in response to current environmental conditions, in the design and successful implementation of management programs.
