On the drop---and dropping fast. There is enough clarity along the edges to find some fish for sure...but be safe out there wading. 1500 to 2000 CFS is still very big on the Gallatin River for fishing. BUT....the river should keep dropping with the cooler weather in the forecast.
If you do go, wade safe, carry a bunch of rubber legs, and stout tippets! Probably a good idea to also fish with a buddy in these bigger flows.
The Month Ahead:
Normally the river is big and full in mid May, but, things can be day to day if a prolonged cold snap happens. A special thing to consider on the Gallatin is water color and clarity. Trout on the Gallatin River will feed in water that contains more color/sediment than many other rivers. In most years, it is the CFS level that deems the Gallatin River unfishable because in certain flows the river is just too high, fast, and unpredictable to safely fish on foot.
