Description Several water quality studies determined that Lake Chelan is one of the most pristine water bodies in North America due to low concentrations of nutrients and other pollutants. The goal of the Lake Chelan Water Quality Plan is to maintain the ultra-oligotrophic condition of Lake Chelan by protecting it from increasing population pressures. A 1989 water quality study of Lake Chelan resulted in a Total Maximum Daily Load (TMDL) which identified sources and estimated total phosphorus (TP) loads due to various land uses. The TMDL also set limits on each of those loads so that epilimnetic TP values would not exceed 4.5 ug/L.
