Instream Flow Progress
Instream flows were set in 1981 (Chapter 173-511 WAC).
The Planning Group recommended existing closures should be maintained, unless new technical information suggests otherwise. It also recommended retaining instream flow levels in the Nisqually River, but doing more work on the Mashel River to improve stream flows and address the water supply needs of the town of Eatonville.
In 2005 Ecology completed Instream Flow Incremental Methodology (IFIM) studies for Mashel River, which included: hydrographs/exceedance curves, estimates of allocated water and actual water use, summary of habitat conditions, and an assessment of hydraulic continuity.
