Lake Cumberland fishing report for April 21st, 2008.   The water temp is 58 on main lake and 60 in the creeks.   The recent warm weather has most fish activity on the rise.   The smallmouth fishing has been good on jerkbaits and spinnerbaits fished on main lake points.   The walleye have been caught casting caught on the same baits but fished on shallow flats where weeds have been recently covered.   The striper fishing has been good most days.   We are catching them very shallow on planer boards fished on the man lake.   The nightg bite is right around the corner.   As soon as we have a couple more warm days it will be good.   Get out and enjoy a great spring fishing day.
