Title:Washington State Lakes Environmental Data Version 1.0
Publisher:Washington State Department of Ecology
Commentsvery dense in north part of lake; Cloudy, light breeze. Egeria densa north of area around Overlake Rd much more dense. South lake with more algae growing on plants, fewer plants and murkier seeming water. Only quickly motored shoreline in most of Duck Lake proper, skipped the canals. Stopped over canal at Overlake Rd and did not see submersed plants growing.
