POST FALLS, Wash.--Rain forced Avista Utility crews to open the spills gates Thursday at the Post Falls Dam.
Avista employees said the recent rain has doubled the flows in the Spokane River within a 24 hour period. The change in water level prompted Avista to open one of the spill gates at the Post Falls Dam.
Opening the gates will impact people living upstream.
Avista workers said the Post Falls boat launch and swim beach at Q’emiln Park is now closed to the public. The boat launch is expected to stay closed through the weekend. People are also asked to stay out of the water between the Spokane Street Bridge and the Post Falls Dam.
Crews closed the Post Falls Dam spill gates and opened the Q’emiln Park boat launch only one week ago.
Avista workers typically make the switch around June 22nd. However, the below-normal spring precipitation and snow pack resulted in below normal river inflows into Coeur d’Alene Lake allowed Avista to close all the Post Falls Dam spill gates earlier than average according to Avista workers.
