Vancouver Lake - History

History

Shortly after the lake was deeded to the Port of Vancouver, WA in 1919, agricultural interests proposed draining it, (A smaller lake to the north, Shillapoo Lake, was drained and used for agriculture) but by the end of the 1920s, recreational uses were also considered. Because of cold weather, the lake was frozen solid to "several inches" in depth on February 10, 1929, and was home to 500 ice skaters one weekend. The lake was briefly considered as a decommissioning harbor in 1945, but after the Memorial Day flood of 1948 was also seen as a possible resource in flood control.

Suburbanization of its watershed area led to an increase in water pollution. Surface runoff brought increased sediment while residential drain fields and increased use of fertilizers rich in nitrogen and phosphorus contributed to eutrophication. DDT was also used for mosquito control until its effects on fish and birds became apparent, and the county discontinued it.

Since then there have been various interests in the area as it relates to habitat preservation, recreation and industry, culminating in the "Habitek" plan of the mid-1980s and the multi-agency Burnt Bridge Creek Watershed Plan of 1995. Algal bloom has been an intermittent problem for recreational use of the lake (officially recognized by the county in 2003) since cyanobacteria such as Anabaena, Microcystis aeruginosa and Cylindrospermopsin raciborskii may produce neurotoxins such as cylindrospermopsin.

The Vancouver Lake Watershed Partnership was formed in October 2004, bringing various public agencies with interest and jurisdiction together.
