The chatfield spillway is one place I have never ventured. When you refer to the spillway, are you talking about the concrete spill structure, that dumps into that square holding area? Cuz I could've sworn that was frozen. Maybe I didn't look close enough though. How do you access it and does the water actually move? I've glanced at it from time to time on my way to waterton but have never thought it would hold much sctructure and flows suitable to trout and fly fishing. I'd like to be corrected if Im wrong because that would be one more convenient place I'd like to try.
