Fishing Conditions

August 20, 2018

The flows out of hebgen dam are great! Its currently flowing at 1160 CFS. There is still enough water to get through most sections without too much scraping on the bottom. The water looks fantastic! Hoppers, ants, and beetles have been the most consistent surface producers. That being said, Don't be afraid of small flies, if the big stuff is not working. These smaller flies can really be the ticket this time of year. The red Lil' Spankers are a small dropper that has been picking up fish all summer. If you are wading, please be careful. If you haven't tried felts or a "foot tractor" - This is the year! Cast tight to the banks and get good drifts under the overhanging trees. PMDs and yellow sallies are coming off during the day and some fabulous fishing is to be had on one of the many braids close to Ennis. Nymphing is always a good back up option. Running smaller nymphs like a serendipity or green machines or prince nymphs can be a great tactic this time of year. Plenty of hoppertunities out this way as well. If the banks aren't producing don't be afraid to fish the middle of the river, or in the shallow riffles. Don't be afraid to throw streamers around with the cooler weather we are experiencing.
