A major component of the Chehalis Basin Strategy, the Aquatic Species Restoration Plan (ASRP) is being developed and implemented through a collaborative, sustained effort.
The initial phase of the ASRP was drafted in 2019 and provides guidance on early actions and immediate priorities for the first 10 years of its implementation. In 2021, the project implementation process was refined with detailed prioritization recommendations and project funding guidance.

ASRP by Region
The ASRP uses the concept of ecological regions to subdivide the Chehalis Basin into 10 regions based on distinct ecological characteristics and processes, so that strategies and actions can be specially designed to work with each region’s unique features and needs.
