Blacksmith Fork River

Blacksmith Fork is the Cache Valley companion to the Logan: a smaller limestone canyon river with browns, cutthroat and rainbows, close enough to town to be useful but far enough from the Provo circus to feel local.

About this water

Blacksmith Fork is the Cache Valley companion to the Logan: a smaller limestone canyon river with browns, cutthroat and rainbows, close enough to town to be useful but far enough from the Provo circus to feel local. For a Californian, this is the kind of northern Utah water that works as an add-on to a Logan / Bear Lake / Idaho border trip — dry-dropper pocket water, summer terrestrials, and a chance at native cutthroat handled carefully.
