Grant funds expended and/or projected through June 2015
In 2000, the state legislature provided additional funding for the Planning Unit to establish a baseline hydrologic assessment, including a groundwater study and model, development of a USGS watershed model, and completion of a water quantity assessment. Golder Associates and the USGS calibrated and collected data from 23 stream gauges, modeling groundwater and surface water in the watershed, and conducted a sub-basin specific detailed groundwater study. Information gathered during these efforts is available from the final Phase 2 Level 1 assessment.
The Okanogan County Commissioners adopted the Methow Watershed Plan in June 2005. Plan recommendations included:
Phase 4 work began in November 2008. Phase 4 Year-1 tasks include developing a detailed implementation plan, and completing several obligations identified in the watershed plan.
Instream flow status
Instream flows were set in 1976 (Chapter 173-548 WAC). The planning group (Methow Watershed council) and Ecology have agreed to revisit the rule after gaining new information and clarifying specific rule changes to be proposed.
