DOLORES — Authorities are trying to determine the cause of a large fish kill at McPhee Reservoir near Dolores.
Fishermen discovered hundreds of dead trout, kokanee salmon and carp on Friday.
Colorado Parks and Wildlife fish biologist Jim White says there can be natural fish kills in shallow bodies of water because of ice and lack of oxygen this time of year. He says toxic pollution has been ruled out as a cause.
According to the Cortez Journal (http://tinyurl.com/jg63fb7), the fish may have been affected by a problem with an intake pipe system that isn't working properly.
