Devils Lake Water Improvement District

Devils Lake in Lincoln City, Oregon is a naturally shallow, coastal lake. It is uniquely placed in the world sitting on the Pacific coast edge of the North American Continent, intersecting the 45th parallel, the mark half way between the equator and the North Pole. Devils Lake is managed by the Devils Lake Water Improvement District.

Devils Lake Submerged Aquatic Vegetation Update

As many lake residents may recall, grass carp were once used to control the overgrowth of submerged aquatic vegetation (SAV) in Devils Lake. However, most if not all of the sterile planted grass carp have died since the latest planting in 1993. Current State regulations prevent the re-introduction of these fish as a biological control in Devils Lake. Recent monitoring suggests some SAV regrowth has begun, primarily in shallower areas where sunlight reaches the bottom of the lake. DLWID is currently working on an SAV plan which will outline options to manage submerged aquatic plants in the greater lake area. In addition, DLWID will be posting an updated Aquatic Plant Survey later this fall which will re-evaluate SAV volume and locations. Currently, property owners may maintain shoreline and areas around their in-water structures (docks, lifts, and boathouses).
