According to the United States Geological Survey, the Madison River just below the dam dropped from a discharge of about 650 CFS (cubic feet per second) to about 195 CFS.

The USGS gauge on the Madison River below Hebgen Lake at 2 am was 1.43' and by 3 am fell to 0.68'.

The Fishing Outfitters Association of Montana reports fish being stranded along that part of the river due to the sudden drop.

FWP is aware of the problem and is on the scene assessing the situation.

FWP Morgan Jacobsen is asking people to stay away because of human safety and the risk to trout redds. Those are the little trenches females dig to lay eggs so males can fertilize.

This is a developing story.
