I'm guessing a little less than 10 foot to the siphon vent intake, which should be around the full pool level. Looking over the fish list for some fall stocking. Put some fatheads, golden shiners, and papershell crayfish in last year. Probably add some more fatheads, bluegill, and red ears this fall. Trying to decide whether to go the LMB-CC route or YP-HSB-SMB route then next summer. I seem to change my mind at least weekly.
