About the Project
Since 2008, the Surface Water Management (SWM) division has tracked and reported the water quality of streams and lakes in an annual Surface Water Report Card. Streams and lakes are graded on a scale of 'F' (failing) to 'A' (excellent). The goal of the "Raise the Grade" project is to improve water quality in streams and lakes with low grades. In 2010, Spanaway Creek was selected for the Raise the Grade program.
In 2011 and 2012, Spanaway Creek received a "C" grade due to low dissolved oxygen and high temperatures. In 2012, Spanaway Lake received a "B" grade due to algae blooms. In 2013, the creek received a "C" grade. Spanaway Creek is not currently on the Washington State 303(d) list of polluted waters, but Spanaway Lake is on the list for fecal coliform. Spanaway Lake flows into Spanaway Creek. For more information about water quality grades, see the Surface Water Health Report Card.
Our water quality inspection staff inspects public
and private stormwater systems around the County annually. Staff did
additional inspections and business outreach in the Spanaway Creek basin
in 2012 to ensure stormwater systems were functioning properly. Inspections program webpage
Pollution Prevention Program
Additional inspectors are assigned to respond to
reports of pollution and look for pollution sources. These inspectors
work with polluters and state agencies to try to intercept pollutants in
the stormwater system before they reach waterbodies. To report
pollution, call (253) 798-4274. Report pollution online
