Fishing in the St. Mary's River rapids can be risky. The water is deep in some areas, and the current is swift. Gates that regulate the water flow can make the current strong and, in some cases, impossible to wade.


  • 0-2 gates open: the rapids are easily fished
  • 2-4 gates open: fishing is still possible, but extreme caution should be used more than 4 gates are open it is highly recommended that you do not fish in the rapids

These recommendations are for informational purposes only. Individual anglers will need to decide for themselves if they should risk fishing in the rapids. It is highly recommended that you fish with someone who knows the waters if you have not fished in the rapids previously.
