Montana Fishing & Hunting Seasons

Fishing Seasons

The Bighorn River is a consistent and productive river year ’round. Due to its tailwater nature, spring run-off is not a problem, nor does the water become excessively low and warm in late summer. In fact, the months of April through June witness some of the best fishing the Bighorn has to offer, while many other Rocky Mountain streams and rivers are overflowing their banks. Each season has different characteristics, however, and can offer the angler a variety of experiences.

Montana Bird Hunting Seasons

The hunting season at Eagle Nest typically begins on Sept. 1 (check regulations for specific dates on public land), at which time Hungarian partridge, and Sharptail Grouse may be hunted. Pheasant seasons opens on October 9th, and we continue to hunt through Thanksgiving. Bag limits were:

pheasant ……. 3 cock birds
partridge ……. 6 either sex
grouse sharptail ……. 2 either sex

September is the best time for those whose primary objective is good Grouse hunting. Sharptails can be found through November. The Hungarian partridge hunting in this area is truely fantastic all three months of the season. October and November present great hunting for pheasants.
