The spawning chronology of bass and Pumpkinseed was determined from direct observations of fish on nests. Results and Discussion Spawning Largemouth Bass spawned in Duck Lake between 20 May and 24 June at water temperatures between 20° and 23° C. Peak spawning occurred in early June. Nests were found in water 50 to 103 cm deep (x= cm, = , n=10). This spawning chronology is similar to that reported for Montana and Washington (Brown 1971; Wydoski and Whitney 1979).
