Lake Coeur d'Alene Water Levels
We are currently unable to provide real-time water temperature data, as USGS.gov has ceased serving real-time water temperature data for Coeur d'Alene Lake to the public as of March 18, 2014. We will be searching for an alternative way of getting you this data.
Lake Coeur d'Alene's temperature typically peaks in July and August with temperatures around 77 degrees Fahrenheit. Water temperatures are generally lowest in February with near-freezing temperatures, approximately 34 degrees.
The highest temperature recorded in 2011 was 73.4o F on August 27 & 28.
The highest temperature recorded in 2012 was 74.7o F on July 20.
The highest temperature recorded in 2013 was 75.9o F on August 13.
The lake has hit its lowest recorded elevation of 2,119.90 ft four times in 1904, 1905, 1906, and 1977. The highest water level recorded on Lake CdA was 2,139.05 ft on 12/25/1933. That's more than a foot above the Major Flood Stage! 1933 was the only known time in history the lake has entered the major flood stage. (note, these figures are elevation. The actual depth of Lake Coeur d'Alene is about 220 feet.)
Avista Utilities, which operates the Post Falls dam on the Spokane River begins its winter drawdown of the lake levels shortly after Labor Day each year. Under its federal license to operate the Spokane River Hydroelectric Project, Avista is required to maintain the lake at a summer elevation of 2,128 feet from as early as practical in the spring until the day after Labor Day. During the drawdown Avista recommends dock owners and boaters should ensure they secure their docks and boats for the winter.
Avista draws down the water levels at a rate of approximately 1.5 ft/month until the lake reaches its winter level.
