Bruneau, Owyhee & Salmon Falls Update
The Bruneau is rising again along with Salmon Falls Creek. The Owyhee had a long and amazing season and is holding steady from the remaining snow melting in the basin.
Owyhee Update !
Remaining snow will help to sustain flows… how long – here are a few similar runoff volumes and recession years. With little weather on the horizon, current snow melt from warm days and freezing nights is ideal.
Owyhee! Let it Flow!!
Here’s an update for the Owyhee based on current snow, flow projections and more weather moving in this week and next. It’s nice to look at big picture to see what’s happening around this tri-state basin.
May 3 – Snow 2 Flow Update for Southern Idaho Rivers
Update for Owyhee, Weiser, Camas, Salmon Falls, Bruneau, Boise & Big Wood

Know your boating limits as rivers will be high for an extended period.
Snow & Flow Update for Apr 12
Following are several graphs illustrating current snow levels and similar years along with resulting runoff. The Owyhee – based on snow2flow relationship just had a snowmelt peak. More rain and warmer temps will produce more peaks. Weiser – always interesting watching the Weiser River react to current conditions as we wait and watch to try to figure out how the higher elevation basins in the state will flow. Camas Creek lots of snow to melt. Bruneau is looking good along with Salmon Falls Creek. Is Banner Summit reaching its peak? Time will tell and then we’ll see how headwaters snow melts and the mighty Salmon River responds. Be safe and know your boating limits.
The Owyhee River rose in March and will rise again in April!
The Owyhee River at Rome increased to 4600 cfs (mean daily flow) on Mar 16 from melting of valley snow and rain for its first peak since last year. The higher elevation snow is still accumulating, even at Mud Flat SNOTEL site which is only 5730 feet in elevations. March precipitation thru March 27 was 144% of median with another storm to continue building the pack as cold will remain until at least early April. Then, get ready as the cold temps will not last for ever…
With an April-July runoff volume of 150% of median predicted, means we could see volumes similar to the first half of the 2019. The 2nd peak on May 31, 2019 depends if the wet /cool spring weather continues into late spring / early summer.
