Teton River Distribution Project: April 2020 Hydrological Report & 4/15 Snowpack Map

Teton River Distribution Project

The Teton River Distribution Project was created by 9th and 12th Judicial Districts Court for the 2017 irrigation season. Water users throughout the basin petitioned for the appointment of water commissioners in 2016. In its inaugural irrigation season, the project proved to be a success based on comments received from water users throughout the basin. Public meetings will be held in the October and November 2017 to address any and all issues that arise during the 2017 administrative effort.

This website is set up in a blog format. Chief Water Commissioner Peter Fritsch is authorized to post photos and comments on stream conditions, priority date cutoffs, etc. Water users may post questions to the blog that will be answered as quickly as possible. This website is an effort to create transparency and effective decision making on behalf of the Teton River Distribution Project.

April 2020 Hydrological Report & 4/15 Snowpack Map

March precipitation was below average in the Sun-Teton-Marias River basin. Storms on March 11th and the 31st brought most of the month’s precipitation. Even after having a record-setting start to the water year, the basin is slightly behind average for water year-to-date precipitation.

With that said, all the basin’s SNOTEL sites currently have above-normal snow water content, which is a result of the significant amount of snow they received before October 1st. Typically, the basin’s snowpack peaks in mid-April, and all non-burned sites have already reached their typical peak
values.

Spring is young, and there is still an opportunity for significant snow in the coming weeks. However, if that doesn’t pan out, the snowmelt driven component this season should not be lacking. Current streamflow forecasts indicate near to slightly above average streamflows are possible for the April 1st through July 31st period.
