Skagit River Basin - Skagit River Management Rule

The Department of Ecology amended the Skagit River management rule to create a secure future source of water for residents and the Skagit River basin, while also protecting "instream" flows of the river.

The new rule amendment will continue to protect fish, wildlife, water quality and recreational uses.  It also keeps the existing 2001 stream flows in place while allocating and reserving surface and groundwater for future agricultural irrigation, residential, commercial/industrial and livestock uses throughout the Skagit basin.

Agricultural Irrigation

A reservation of 3,564 acre feet of water is available for future commercial agricultural irrigation for either ground or surface water in the Lower, Middle and Upper Skagit sub-basins. Potential users of this reservation will need to obtain a water right from Ecology.

Domestic, Municipal, Commercial/Industrial and Stock Watering Uses

A reservation of a maximum average consumptive daily use of 9,370,208 gallons per day of water is available for domestic, municipal, or commercial/industrial water supply not subject to the instream flows.  A reservation of 324,000 gallons per day of water is reserved for new stock water uses not subject to instream flows.  It is available to users exempt from the permitting process and to users requiring a water right.  The quantity of water reserved would not significantly impact fish habitat.

Skagit Water Reservations 2007 Annual Report

In consultation with local governments and tribes, Ecology developed an amendment to the Skagit Instream Flow Rule, WAC 173-503, which was adopted May 2006. The rule amendment established reservations of water for specific out-of-stream uses that are not subject to instream flows. The rule created three reservations of limited water supplies for different purposes of use:

Applicability of the Water Reservations

This report summarizes water uses from April 14, 2001 to December 31, 2007 utilizing the reservations.  The reservations apply back to April 14, 2001 in order to provide uninterruptible water supplies for water users that established their water use after the original Skagit Instream Flow Rule (WAC 173-503) was adopted, on April 14, 2001.  Under the original rule, all water uses established after this date were subject to regulation when the senior instream flows were not being met.  The rule amendment recently adopted by Ecology allows wells developed after April 14, 2001 a legally secure water supply by including their uses under the reservation.

Skagit River Facts

  • Size: The Skagit River is more than 160 miles long and the third largest river on the West Coast of the contiguous United States, after the Columbia and Sacramento rivers. It provides about 20 percent of the fresh water flowing into Puget Sound, or nearly 10 billion gallons a day.
  • Location: The river originates in Canada then flows south and west through the North Cascade Range. With some 2,900 tributaries, it drains 3,130 square miles of watershed in 2,730 square miles in Washington and 400 in British Columbia.
  • Animal Species: 5 species of salmon, globally rare Salish sucker, neotropical migrant birds, bald eagles, fishers, grizzly bear, wolves, trumpeter swan, gray-bellied brant, and many raptors and waterfowl. The Skagit is the only river system in Washington which supports all five species of salmon. It contains some of the largest and healthiest wild Chinook salmon runs in Puget Sound and the largest pink salmon stock in Washington.
