Echo Lake is located in Shoreline, Washington, a suburb adjacent to Seattle. Echo Lake Park sits on its northeastern corner.
Echo Lake has played an important role in Shoreline's history. During the 1800s, logging was a significant industry in the region. In the early 1900s, Mowatt's Sawmill operated at the north end of Echo Lake.[1]
From 1916 to 1996, the lake had a bathing beach that cost a nickel for admission. The lake was a center for social life, especially during the summer. Apartment buildings now stand on the former beach site.[2] [3] [4]
Echo Lake Park contains popular amenities such as a beach, paved trails, a playground, and public art.[5]
Echo Lake is stocked with rainbow trout by the Washington State Department of Fish and Wildlife.[6] The lake suffers from high nutrient levels (eutrophication), causing algal growth and impacting water quality. In April 2021, these conditions led to algal blooms containing anatoxin, a highly toxic chemical. This led to a temporary lake closure.[7] [8]
