Publication Summary

The Department of Ecology is proposing Chapter 173-505 WAC to set, achieve and protect in-stream flows and create a water management program. Objectives include setting instream flows that define levels needed for fish and all other instream values for areas including the Stillaguamish River and tributaries and all contributing land area as set forth in chapter 173-500 WAC. A draft rule has been developed that closes areas during certain periods, creates reservations for domestic and stockwater uses and clarifies the requirements for out of stream uses. Ecology has conducted this benefit-cost analysis as part of the rule adoption process.
