Bighorn River Fishing Report: Thermopolis, Wyoming: No Spring Flush this year on the Bighorn River according to the Chief of Water Operations. Typically, every March the Bureau of Reclamation will conduct a spring flush to wash out sediment and debris from the river to help with spawning and trout habitat. However, due to the high water we have seen this last year and through the winter there is not a need to have a spring flush. River flows are projected to increase to 2000 CFS in the next few days and will probably reach 3000 CFS by the end of the month. River flows from then on will be highly dependent on what spring will bring with moisture and melt.
Fishing on the Bighorn River has steadily gotten better from the middle of winter. Warmer weather is helping the fishing and bringing quite a few anglers eager to shake the cabin fever to the river. We ask fishermen to avoid fishing to podded up rainbow trout on their redds (spawning beds) in shallow water. Fish the drop offs and deeper runs and you will catch just as many fish. Hot flies right now include: sow bugs, midges, annelids, leeches
