Publisher:Washington State Department of Ecology
Commentsa couple patches in shallows, also more in water about 3 m deep; Cloudy, calm. Only visited the Juanita Bay area, to look for Egeria dansa. Found a few rooted patches in Juanita Bay in front of the wetland area. Dense surfacing milfoil in 1-2 m water. Observed much waterfowl, herons. Kirk Smith also reported seeing Egeria fragments, and maybe rooted plants at the northern end of the lake, around Sheridan Beach.
