I grew up fishing in the Elkhorn...specifically around Frankfort. The creek was considered public land. So unless they sneaked in a law change, I have no idea. There was an old judge who had property adjoining the creek where we'd wade fish. He used to come out and yell at us to "get off his property". Every time we'd yell back, "KMA! You don't own the creek, A-hole!" Maybe the old jerk ruled a change of that.
