Predict the Peak 2021!

Predict the Peak 2021! 

Each spring as snowpack melts in the mountains, the runoff brings the highest flows of the year to Montana’s Rivers. This “peak flow” changes year-to-year in timing and volume, and is becoming increasingly variable. Climate change is causing rising temperatures, lower snowpack, earlier runoff, and variation in precipitation, all of which affect the health of our streams and rivers.

PREDICT THE PEAK 2021 3 rivers this year. The Yellowstone, Gallatin and Bitterroot Rivers.


Please join us for PREDICT THE PEAK 2021! A fun way to engage and contribute to the protection of Montana’s rivers by guessing what the peak flow will be. For this fundraiser, we ask folks for a set donation per guess (in cubic feet/second, cfs). Make as many guesses as you like!

Your donations will help us continue to protect rivers and streams in Montana. Thank you for your support.
