Water Flow Information
Updated daily
This morning, Avista was alerted to an incident involving a crane failure from an Avista contractor on the Post Falls North Channel Dam Spillway.
We understand that an employee of the contractor was injured in the incident and has been transferred to a local area hospital for treatment of non-life-threatening injuries. Our hearts and prayers go out to the individual and their family.
At this point, the crane failure does not appear to have caused any significant damage to the dam structure or impact on generation at the powerhouse. We likewise do not expect that the incident will result in any downstream impacts or flooding.
Avista is working with the contractor and incident command team to understand how the incident occurred and the steps for securing the site. As more information becomes available, Avista will provide additional information.
Water conditions as of Tuesday, October 29, 2024. Please be aware that water conditions can change drastically at any time depending upon weather and dam operations.
Coeur d'Alene Lake
The elevation of Coeur d'Alene Lake this morning is 2125.59, which is about 2 feet 5 inches below maximum summer level. We have begun our annual fall drawdown of Coeur d'Alene Lake. Target elevation for end of November is about 2123.5 or 4 1/2 feet down from maximum summer level. The boat launch at Q’emiln Park is open and the river will remain open until November 11 for recreation above the boater safety cables at Post Falls Dam.
Spokane River between Coeur d'Alene Lake and the Post Falls Bridge
The following information is concerning water levels between Coeur d'Alene Lake and the Post Falls bridge. The present water level at the Spokane Street Bridge is 2125.3, which is about 2 feet 5 inches below normal summer level. We expect the level of the water above the dam to go down slowly over the next week.
