Avista to conduct natural resource surveys by helicopter in Spokane River watershed

Avista will be conducting two days of natural resource surveys by helicopter between Thursday, March 26, and Friday, March 27. 

This work is part of ongoing environmental monitoring efforts within the Spokane River Watershed. During the survey period, people in the community may see a helicopter flying as low as 250 feet above the ground between the hours of 8 a.m. and 4 p.m. 

Survey locations include Lake Coeur d’Alene, 30 miles up the Coeur d’Alene River, 30 miles up the St. Joe River, 9 miles up the St. Maries River, and near the Spokane River, Nine Mile Reservoir and Lake Spokane. 

Residents and recreationists in these areas may notice brief periods of helicopter activity as crews move between survey locations. The flights will be temporary and are limited only to daylight hours.
