A planned water release at the spillway of the Bighorn Dam will raise the water level of the North Saskatchewan River and affect downstream communities, TransAlta said Tuesday. The spillway flows into the North Saskatchewan River west of Nordegg in north-central Alberta. "River flows will increase over several days and reach approximately 175 m3/s. TransAlta is working with the provincial government to temporarily restrict access around the Bighorn Dam for the water release. The Bighorn plant is one of two TransAlta hydro plants on the North Saskatchewan River system.
