FORT COLLINS, Colo. (AP) – Wildlife officials are asking for the public’s help to determine what caused thousands of fish to die in a northern Colorado river.
The Fort Collins Coloradoan reports Colorado Parks and Wildlife is asking if anyone noticed changes in water quality or fish behavior on the Poudre River between Sept. 19 and Sept. 21.
CPW spokesman Jason Clay says the agency has an idea of how many fish died but isn’t yet releasing that estimate.
Fish kills are often caused by changes in water temperature and concentrations of dissolved oxygen, as well as low flows.
Officials have taken water samples and surveyed the fish population in the area of the fish kill and have narrowed down possible causes.
