OLYMPIA, Wash. — The Department of Ecology (Ecology) declared a drought emergency for most of Washington state on Tuesday due to low snowpack and forecasts predicting dry and warm spring and summer seasons.
Service areas encompassing Everett, Seattle, SeaTac and Tacoma are the only spots excepted from the declaration. It's the fourth-earliest drought declaration on record in Washington, according to Ecology.
A drought is declared in Washington state when there is less than 75% of the normal water supply and there is a risk of "undue hardship," according to Ecology. The current drought emergency declaration is a continuation of the conditions that led Ecology to declare a drought in 12 watersheds across the state last year, the department wrote.
Washington had an exceptionally dry winter, and although the snowpack managed to make up some ground between February and April, there is not enough water contained in mountain snow and reservoirs to prevent "serious impacts for water users" in the upcoming months, Ecology said in a press release.
The drought emergency declaration will make assistance available before impacts of low water supply become "severe."
Ecology also tweeted on Tuesday that areas of the state are expected to see the lowest levels of streamflow on record. This raises serious concerns for fish and other species, according to the Department of Fish and Wildlife.
Statewide, the snowpack currently stands at 63% of average, with some areas in the Olympic Mountains, Lower Yakima and north Puget Sound with significantly lower levels. Stream flows in many basins are already below 75% of normal, according to Ecology. Chelan River stream flows are expected to be 52% of normal, and the Stehekin, Methow and Okanagan rivers are forecasted to have 59% of normal stream flows.
The earliest declaration was on March 10, 2005. In 2015, Ecology declared a drought for three regions of the state on March 13, which was the expanded to the entire state in May 2015. The third-earliest drought declaration was on March 14, 2001. This year's declaration, April 16, is the fourth-earliest, according to Ecology.
