Rainbow Trout
Looking for Rainbow Trout near Cambridge, Idaho? You're in luck – the area is surrounded by excellent trout streams. The Weiser River and its tributaries, like Mann Creek, offer opportunities for both stocked and wild rainbows. Spring and early summer are ideal, as runoff subsides and the water clears. Fall can also be productive before the winter freeze. For the Weiser River, focus on riffles and pools, drifting nymphs or casting small spinners. Mann Creek is smaller and more intimate, perfect for fly fishing with dry flies or small streamers. A helpful hint: Check the Idaho Fish and Game stocking reports to see where recent plants have occurred. Also, be aware of private property along the river; respect landowners and access points. The rainbows in this area are generally in the 8-14 inch range, with the potential for larger holdovers. Keep an eye out for mayfly hatches for some exciting dry-fly action.
