The “town” section of the Boise River is an urban tailwater that flows directly through Idaho’s capital city. Its crisp summer flows and scenic cottonwood backdrop attract recreation enthusiasts throughout the state.
Currently managed as a “put and take” fishery, the river in town is probably our most under-rated piece of water in the region. However, to those who take the time to learn it’s structure, there are plenty of opportunities to be had. It’s not uncommon to find sections of river holding very large wild browns and rainbows up to 22 inches in length (and some larger).
Caddis and PMDs top the hatch charts throughout the heat of the summer. However, many anglers prefer to nymph riffles and strip streamers along undercut tree-lined banks.
In the early fall the river transforms as the water levels drop, fish pod up, and Tricos dance in the early hours. On typical mornings you can expect to find heads up on spinners. Into the afternoon, they begin keying on BWO duns.
Regardless of what’s hatching or how you prefer to fish, the Boise River in town is great place to explore and enjoy a piece of urban trout water.
