Lake Description & Overview
Loon Lake has little residential development with 2 single family homes on the west side of the lake and one cattle grazing area on the south side. It is apparent that cattle grazing extends to the water edge and is potentially used as a water source. This certainly is a significant nutrient source to the lake. There is a prominent wetland fringe along the western and northern shoreline.
Water quality was monitored for a three year period from 2006-2008 with total phosphorus concentrations of 29 ppm and water clarity of 6.5 feet. This is well within the expected range for this ecoregion (23-50ppm phosphorus and 5-10.5 ft clarity) and well below the impairment limits for shallow lakes (60 ppm phosphorus and 3.2 ft clarity). Loon is a landlocked lake, meaning there is no surface water inlet or outlet, and is disconnected from all surface watercourses.
