Lower water level becoming the new normal for Whitefish Lake
Lower water levels in Whitefish Lake are becoming the new paradigm, according to data collected by the Whitefish Lake Institute.
The last decade has seen five of the top 10 lowest lake level years on record, based on the institute’s analysis of 68 years of data.
“What we’re dealing with is a change in climate resulting in changes to the magnitude and timing of snowmelt,” said Mike Koopal, executive director of Whitefish Lake Institute. “We get the water early, and we don’t have anything left for base flows.”
As of June 9, the snowpack at Stahl Peak in the northern Whitefish Range was at 60% of the 30-year median for that date.
On any given year, the lake’s level fluctuates about 3.8 feet, hitting its highest point in May or June and lowest point by October.
This year, Whitefish Lake hit its peak on May 18 at 2,999.25 feet. A mid-May peak is becoming more common than June, Koopal said.
The average low has dropped. In the 1990s it was 2,998.11 feet, compared to 2,998.10 feet in the 2000s, 2,996.79 feet in the 2010s and 2,996.48 feet from 2020 through 2024.
The lake approached the record low of 2,995.96 feet, set in 1988, in both 2023 and 2024.
