BRIGHTON, Colo. — A recent algae bloom combined with high water temperatures is killing fish at Mann-Nyholt Lake. In a tweet Friday, Colorado Parks and Wildlife (CPW) said they were notified about several dead fish at the lake located in Adams County. According to CPW District Wildlife Manager Jerrie McKee, the conditions were caused by several factors, including higher water temperatures, lower levels of running water that feeds the lake, and a recent algae bloom that have resulted in lower levels of dissolved oxygen available for aquatic life.
