River Description
The Grimes-to-Robie section of Mores Creek is a pleasant change of pace from everything else immediately surrounding the Treasure Valley. With the put-in being less than an hour from Boise and nearly 100% roadside rapids, it is a great option for those seeking a change of pace during spring runoffs.
This Spring run features a steep gradient but few significant rapids. You can expect to be moving at a decent clip at most times, but everything is read-and-run with very few must-make moves. This is an excellent section for beginner/intermediate paddlers seeking to improve their river reading skills and to experience more technical paddling without major conseqences. The biggest hazards are man-made: at various levels, you may have to duck under bridges, cross-river cables, or illegal rope lines at water level.
There is a wonderful surf wave halfway down the run behind a private home. The owner created a rock dam for a summer soaking pool that creates a clean river-wide green wave.
If you're looking for a change of pace or waiting for the other Treasure Valley runs to reach a more suitable flow for your skill level, grab your dry gear and enjoy this run before it dries up in April/May
