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.
Update for Selway Lochsa Moyie Owyhee Bruneau Wood Lost and more Idaho rivers. Keep your eye on the weather as one more AR moves in next week.
Here’s an update for the MF, Main, Lochsa and Selway Rivers showing there’s enough remaining snow to generate another increase in flow the next few days. This may be the last week of cooler/wetter spring weather with forecasts hinting at warmer/nicer weather for June’s arrival. Keep an eye on the sky watching the weather, and your mouse on snow melt and river levels pages as we see how high the rivers rise from this pulse of water coming out of the mountains. Enjoy & be safe !
Here’s a quick update that shows agreement with snowmelt relationships and snowmelt peak flows. Cool temps will slow remaining melt and push flows out a bit when warm temps return.
Short summary presented at the State’s May Water Supply Meeting about the following:
May 7 Snow2Flow update – with return of warm weather, rivers will rise again to generate another peak from remaining snow with temps pushing 80s F in Boise. Air temps and duration of warm spell will determine how fast the snow melts, how high the rivers rise and when the snow runs out that feeds the rives. Enjoy and be safe!
Low snow means low flows in these basins. Hopefully more weather moves in during the month of May
Snow & Flow Update — And Owyhee is up !
Here’s an update for Selway & Lochsa Rivers based on Jan 1 & Jan 28 that shows the current snow, chance to recover, and plots of other strong El Nino years along with analog years. We’ll keep an eye on using 2010 as another analog year for this winter and watch how it tracks else in the state too. Enjoy spring skiing this week but stay tuned as we still have 40% of winter to go and winter returns in early February (this weekend)!
Snowmelt peaks flows have passed but June rains can generate additional increases. Didn’t realize the Moyie River is flowing near record low and exactly the opposite of 2022.
