Title: Land use activities in eleven agricultural watersheds in Southern Ontario, Canada, 1975-76
Author: Frank, R.; Ripley, B. D.
Abstract: Project 5 - Land use activities - was designed to collect and compile detailed information on land use practices in eleven selected watersheds located in southern Ontario. The information on material inputs in the watersheds was intended to help in the interpretation of output parameters that were measured in the water leaving the mini-watershed on the way to the Great Lakes. The project was also intended to help identify mini-point sources as well as non-point sources or diffusion inputs of materials. Control of these sources may become of great significance as known point sources of inputs are reduced. To determine various land use parameters, eleven mini-agricultural watersheds were surveyed by questionnaire; ten were surveyed in 1975 whereas AG-5 was surveyed in 1976. These selected watersheds were typical of larger areas in the Province with respect to soil type, topography and agricultural activity. The selected mini-watersheds were located in southern Ontario on ten larger watersheds draining into the Great Lakes; three drained into Lake Huron (Ausable River, Maitland River and Saugeen River), one drained into Lake St. Clair (Thames River), three drained into Lake Erie (Big Creek, Grand River and Hillman Creek) and three drained into Lake Ontario (Humber River, Shelter Valley Creek and Twenty Mile Creek).
