Castle Rock Creek · about
Background · character · contributors
A spring creek of the chalk-stream kind — weed-trailing, alkaline, absurdly productive — with a reputation for big browns that didn't get big by being stupid. Grant County's limestone country makes the water hard and fertile, and the fish behave accordingly. This is fine-tippet, watch-the-rise-form fishing.
