Here’s a Snow 2 Flow Update for the coming season. And remember to check out this Snow2Flow Verification post about using snowmelt rates to help prediction snowmelt peak flow dates or see if the peaks have passed. https://snowweatherandflow.blog/2026/01/22/snow2flow-verification-for-years-2023-24-25/
Ski ya later !!
It’s always good to verify forecasts to better understand what works, and why or why not. This provides a better understanding of the relationship, other climate influencers that may have impacted the outcome and when works best. Following is a summary of Snow2Flow relationships used to predict date of peak flows, range of dates, and if the potential for additional snowmelt peaks has past or is decreasing
Snow & Flow graphs illustrate what happened and how the predictions preformed. 2026 SWE is also include to give you a hint how this winter is tracking these recent years. Next post Idaho’s Four River Lottery – Where’s the Snow and Flow Going in 2026 ?!
When you see the Buffalo Fork snowmelt runoff peak happen in the upper Snake River basin, you know the snowmelt runoff season is winding down. Here’s an update with similar recession years to help in monitoring this year’s flow. Projections are made for some rivers if a peak wasn’t happening.
Alphabetical flow graph summary – includes most Idaho rivers across the state and similar runoff years. Short on time to do full analysis but wanted to share.
For MF, Main Salmon, Selway & Lochsa and a few more – Owyhee, Bruneau and Salmon Falls Creek. Enjoy, be safe and keep and eye on the weather and flow levels for changing conditions.
Snow2Flow Update for: MF & Main Salmon Rivers – Selway & Lochsa Rivers and a few more: Owyhee, Camas Creek and Salmon Falls Creek
Snow is melting, rivers are rising, enjoy and be safe. Know your limits.
Here’s a snow & flow update for the Salmon, MF and Selway rivers and a Lochsa Bonus. Current snow conditions are displayed with analog years mentioned in previous posts. Streamflow forecast are from the NWS around Jan 20 and compared to observed runoff the analog years. January 15 is consider the half way point for winter. Overall the snow is in good shape because of the great start, but more snow is need after this dry January as show in image below.
With some moisture moving in this weekend, we’ll soon see which rivers benefit from the moisture and which basins the moisture helps to slow the fires progress. This update has a few weather outlooks, and projected flow graphs along with comparisons to see how the Aug 6 flow projections preformed. Projections were pretty good. Rivers are easier to project when they are approaching their seasonal lows for the year.
