The East Gallatin is no longer hoot owled from Penwell Bridge Road to the confluence with the West Gallatin at Nixon Bridge, but flows are low and water temperatures are still high, so be conscientious if you do decide to fish out here and avoid fishing once water temperatures exceed 67 degrees. During August the East Gallatin is not normally the best option for fly fishing near Bozeman. And this year is holding serve...because the East Gallatin is one of the lowest elevation and low gradient rivers in the Bozeman area, flows are low during late summer. If you do fish the East Gallatin there may be some opportunities early in the morning, but it is still a bit tricky crossing from bank to bank in some places without trespassing above the high water mark.
Expect early morning caddis or PMDs, possibly some Tricos, but not much after the sun gets high and starts to really penetrate the water.
