oxygen concentrations, little algae growth, and clear water. Eutrophic lakes have high nutrient levels, low <br />oxygen concentrations, high algae growth, and murky water. <br />Sources of phosphorus to lakes include the atmosphere, stormwater runoff, and internal cycling. The <br />atmosphere contains phosphorus in dust and other particles transported into it by wind and re- deposited <br />by rain and snow events. Stormwater runoff also carries phosphorus. Generally, as land use intensifies <br />and the percentage of hard (impervious) surfaces increase, the amount of phosphorus in runoff also <br />increases. Internal cycling is an important factor in most lakes. This is the process where phosphorus that <br />had settled to the lake bottom seeps back into the water during the summer, the time when nuisance algae <br />are problematic. <br />A summary of available data from the 2010 Rice Creek Watershed District Watershed Management Plan <br />for each lake is provided below. Where noted, additional data was presented from the Department of <br />Natural Resources' LakeFinder and the Minnesota Pollution Control Agency's Environmental Data <br />Access system. <br />Rondeau Lake <br />Rondeau Lake has a surface area of 275 acres, a watershed area of 3,448 acres, and a maximum depth of <br />7 feet. Rondeau is classified as a shallow lake and is managed to support aquatic life and enhance passive <br />recreational uses. Rondeau is not listed as an impaired water body. <br />Peltier Lake <br />Peltier Lake has a surface area of 483 acres, a watershed area of 65,989 acres, and a maximum depth of <br />16 feet.
