Like much of the west, June has been unseasonably hot in Yellowstone Country. Typically, temperatures range in the high 60’s to low 70’s with lots of rain. But this year, we’ve had 17 days over 80 degrees and seven days over 90 degrees with almost no precipitation. So as you can imagine, it’s dry out here.

Naturally, the rivers and lakes serve as a reprieve from the heat, but many rivers are experiencing low flow and warm temperatures, creating a stressful environment for fish. Elsewhere in Montana, “hoot owl” closures are in effect, meaning fishing is closed from 2:00 p.m. until midnight. These closures are designed to protect fish susceptible to disease and death in drought and warm water. While these closures haven’t yet taken effect in YC’s rivers, Montana’s Fish, Wildlife, and Parks ask anglers to fish during the coolest times of the day, land the fish quickly, keeping it in the water as much as possible. Then, remove the hook gently and let the fish recover before releasing. Artificial Lures with single and barbless hooks can make the hook removal faster and easier.

Ultimately, it’s best to fish the cooler waters such as Hebgen Lake or high alpine lakes when the flows and temperature of the rivers get too low and warm. 

With an increase in residents and visitors, Fish and Game Wardens remind people of the fishing and boating regulations. Don’t forget your fishing license. It’s a good idea to print and carry a hard copy but save a backup copy as a pdf on your phone; many areas do not have cell service.

Validation Decals on Boats

AIS Check Stations:

Inspections are essential to prevent invasive zebra or quagga mussels from entering Montana’s waters. This season has seen a significant increase in the number of boats found carrying them, due partly to a rise in the number of boats and an increase in mussels. Always clean, drain and dry your watercraft after each boat outing.

Be sure to drink a significant amount of water and use sun protection, including lip sunscreen, a hat, and sunglasses.
