Here’s a summary of the 2025 runoff, the fall and early winter weather that created the unique elevational distribution of the snowpack and water supply outlook for the Payette, Boise & Owyhee basins. This talk was for the Idaho Alfalfa & Seed Growers Conference.
Here’s a summary of what happened to last year’s runoff because of near record dry spring. Summer is over and Fall precip is moving with a huge Atmospheric River tail that stretches over 1000 miles to SE Asia. Winter Outlooks for 2025-26 with analog years based on similar ocean conditions; we’ll watch and updated as we progress into winter. For now enjoy the wet weather as we start the new water by building our mountain snowpack.
Idaho Museum of Mining & Geology talk from March 9 about 1. Current Ocean and Atmosphere Teleconnections, 2. Conditions Leading to this Year, 3. 2024 Extreme Weather & Natural Disasters, 4. Current Stream, Snow and Water Supply Forecasts with Highlights for the Payette, Boise and Owyhee Basins, and Weather Outlooks.
Here’s a talk given to Idaho Alfalfa & Clover Seed Growers about current conditions, analog years, acres burned, a few slides about 2024 extreme weather and disasters, and the snow & flow outlooks for the Weiser, Payette, Boise and Owyhee basins. With high, dry and cold weather here for a bit, we’re gonna loose about 1% a day, but the snow won’t be melting. Cold is good! We’ve seen winter dry spells in other years and lucky for us, SW Idaho got off to a great start this winter. Let the 2nd half of winter start – any day now…
