Dworshak Dam turbine under repair, may increase summer water temps


Dworshak dam, a major water storage resevoir on Idaho's Northfork of the Clearwater provides an important source of cold water releases throughout the summer months. Without these releases temperatures in the lower Snake can rise above federally mandated guidelines causing increased stress and potentially mortality among upriver migrating Chinook and Steelhead. Due to maintenance problems however, the primary turbine system at Dworshak is temporarily out of commission potentially jeapordizing cool water releases while operators repair a leaky seal.
