There are approximately 656 acres of land, and 1,034 acres of lake surface within the District. The Lake Stevens Watershed totals only 3300 acres. This small area feeds the largest lake in Snohomish County. Five streams drain into Lake Stevens. There is only one outlet, the Lake Stevens Outflow Channel, which drains to Catherine Creek.
Water entering Lake Stevens is estimated to remain there on the average of eight years.
Both are thus highly impacted by all up-stream activities. Impacts include both water quantity and water quality issues. This situation requires the District to engage in numerous and varied activities to protect the lake, and all its inhabitants. The District continues to utilized its limited resources to take the necessary steps to implement a plan for a healthy watershed that protects and preserves its fish and wildlife habitat while servicing the surface water management needs of a growing residential population.
