1977 Conestogo Reservoir: A preliminary water quality survey

Abstract

Conestoga Reservoir was one of four reservoirs surveyed during late Spring, Summer and early Fall, of 1977. The purpose of the study was basically twofold, to determine the effects of a reservoir on downstream water quality, and to establish reservoir water quality. Stations were established on the inflows, the outflow and 3 surface and bottom stations within the reservoir. Samples were collected weekly from the surface and one metre from the substrate employing a Kemmerer bottle and taken to the lab for analysis. Dissolved Oxygen and Water Temperature were obtained employing a YSI-Dissolved Oxygen metre, as were Dissolved Oxygen-Water Temperature Profiles. BOD5 samples were analysed using the YSI BOD probe. All other chemical parameters were measured with the Hach DREL kit. Stream samples were Monitored in the same fashion.
