Fishing Southwest Idaho
Fishing Southwest Idaho
Anglers come from all over the country to fish these waters. Why? Because Southwest Idaho features a wider variety of fishing experiences than just about anywhere in the country. From big rivers to small streams and large mountain lakes to urban ponds, we have it — in settings ranging from the deep canyons of the mighty Snake River to remote streams brimming with native cutthroat.
Grab your gear, and let’s go…
Getting an Idaho Fishing License
The Snake River features spectacularly big views (to match the fishing).
- First things first, you’ll need an Idaho fishing license. Special permits are needed for salmon and steelhead, so be sure you know what you’re angling for before purchasing. Get yours at any Idaho Fish and Game office, most sporting stores, local grocery stores like Fred Meyer and Alberstons, over the phone at 1-800-554-8685, or from IDFG’s website. You’ll be an o-fish-al angler in minutes!
- Be prepared! Idaho’s remote mountain lakes and our rapidly-changing weather require good preparation. Check conditions before you head out and throw a small first aid kit in your bag just in case.
Didn’t pack your equipment? No worries. We’ll talk about our favorite options for local rentals and purchases below. - Help us keep Idaho pristine. Follow a few basic etiquette tips to keep fishing fun for everyone. Be sure to:• Pack out what you pack in.
• Give other anglers space. Leave enough room to avoid line tangling.
• Stick to fishing on public land. If you want to fish on private land, you’ll need permission from the owners.
• Keep invasive species from spreading by cleaning boating and fishing gear thoroughly after you’re done.
Idaho Fish Species

Idaho has 42 species of recognized game fish. Some are plentiful and easy to land, while others are rare and prized by expert anglers. Here are a few of the species that seasoned anglers will want to seek out:
- Rainbow Trout: These acrobatic beauties are widespread throughout Southwest Idaho thanks to healthy native populations and generous hatchery-raised stocking programs. While most are under 12”, Idaho’s record rainbow was a 20”-er pulled from the Snake River.
- Brown Trout:

Catch bass & other warmwater species using a fly, lure, or live bait.
Ocean-going steelies can be caught right in town, as well as on a more remote stretch of the Boise River.
Give this fish identification reference a look before you begin. Bagging limits and rules are dependent on the species, region, and season, so be sure to check Idaho Fish and Game’s fishing guide when planning your trip.
