Surface to bottom water temperatures were mea...sured over deep portions of these lakes with a thermistor and probe. Instantaneous temperatures v/ere read with a pocket thermometer in association with all investigative actions. Substrate composition of artificial and natural spawning sites was taken with the aid of a 2-pound coffee tin. Grain-size analysis followed the procedures of Welch (1948) . A Price-type current meter and a staff gauge was employed in the outlets of Sylvan and Lightning lakes, and flows were converted to cubic feet per second.
