Our River Conditions map displays Big Hole River stream gage locations and readings, Big Hole River Drought Management Plan trigger locations, and developing streamflow and temperature trends. *Please note: Many of the gages on the map below report seasonally, making streamflow and temperature readings unavailable November-May.
Thank you to George Grant Trout Unlimited for covering the annual operating costs of the Big Hole River’s three temperature gages since 2021.
ABOUT THE RIVER CONDITIONS TOOL
This version of the River Conditions web tool was developed by the USFWS and the Missouri Headwaters Partnership in 2018. It was developed with input from the BHWC and is based on a similar tool first created by the BHWC in 2016.
BIG HOLE RIVER DROUGHT MANAGEMENT PLAN
SHARED SACRIFICE, SHARED SUCCESS
The Big Hole River Drought Management Plan designates target river flow and temperature conditions for fish health in five river sections of the Big Hole River. The plan includes voluntary conservation targets for all water users, MFWP fishing restriction criteria, and information tools. Conservation actions are designed support the health of the fishery.
The plan outlines voluntary conservation actions and relies on Shared Sacrifice, Shared Success – if all users sacrifice, we can all be successful in protecting the fishery. The plan also designates MFWP fishing restrictions when drought conditions reach critical levels.
The BHWC DMP originated in 1997. The plan is reviewed annually by a committee made up of irrigators, fishermen, conservation groups, and agency representatives as well as the entire BHWC.
