Snow & Water Supply Outlook from Jan 9 2024
Here’s an update of fall streamflow & soil moisture conditions leading into winter, other strong El Nino years, 2024 Analog Years, chance for Owyhee & Boise basins snow to recover to normal by April 1, and a few streamflow forecasts. More posts and snow will be dropping…
Review of La Nina Analog Years from June 2023
Keep in mind, Pete’s analog years are based on current Pacific Ocean and atmosphere conditions to generate awareness of current conditions and precipitation and temperatures outlooks based on
analog years. They were never intended to zoom down to a basin level or individual station, but let’s have some fun, give it a try to see how they worked to give us a heads up about the winter snowpack for Twin Lakes SNOTEL, Boise Basin and Bogus Basin SNOTEL.
Flow Update for Northern Idaho
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.
Flow Update for Southern Idaho
Snowmelt water is still feeding our rivers with enough from the higher elevation basins to generate another increase in the Big Lost River and Teton River. Weather outlooks are trending with more of the same weather for the rest of June – cool in southern Idaho / Nevada and warmer towards Seattle.

Bruneau Snow & Flow Update
Here’s a short update, just dont tell Mike… The Bruneau is unique place, lets keep it that way. There’s enough snow to produce another increase, but the wild card are the extended period of hot temps. I didn’t look to see how much if any rain fell in May 2006 that added to flow increase.
