Potamogeton crispus is an early senescing species that is present in the lake between early May and mid-June. Because P. crispus dies off early in the season, it generally does not create issues with recreational access. Furthermore, the population of P. crispus in Lake Beseck was significantly impacted by the dam repair in 2013; that repair required that the lake be drained to about 10 percent capacity. The draining of the lake resulted in the exposure of the littoral zone to winter temperatures and dewatering of the lake sediments. Freezing and drying have a significant impact the reproductive structures of all aquatic macrophytes including P. crispus. Since that time, the population of P. crispus has remained small and has not significantly affect recreational access |
