2026 Water District 1 Weekly Reports

Water District 1 Weekly Water Reports

MID is sharing the weekly Water District 1 reports to help keep our water users informed throughout the irrigation season. These reports provide updates on snowpack conditions, river flows, reservoir storage, and projected water availability across the Upper Snake River Basin. Because this is expected to be a tight water year, we want our waterusers to have direct access to the same information we are using to monitor conditions and make operational decisions. We will continue posting these reports as new updates become available.

Weekend precipitation brought a significant shift in basin conditions, ending the Upper Snake River reservoir system’s seasonal drawdown and marking the beginning of the storage season. Water-right priorities have reconnected at Blackfoot, with storage now accumulating under the 1906 Jackson and 1909 Walcott rights, while most canals have completed or are nearing the end of irrigation deliveries. The reservoir system remains very low at approximately 9% of capacity, but recharge operations in the Lower Valley are expected to begin October 20.
