Lamar Lake provides drinking water for the City of Lamar. This 147 acre lake has a 3055 acre watershed that is comprised of 11% forest, 65% grassland, 15% cropland, and 4% urban. The high ratio of watershed size to lake volume limits the ability of Lamar Lake to dilute and settle out inputs of nutrients and sediments.
