"Where is the spillway..."
Spillways (wether the water flow is fresh to fresh, fresh to salt, or salt to salt) are gamefish attracting magnets. The constant flow of water means gamefish can sit and wait for food to be washed right to them. Snook, tarpon, largemouth bass, and a host of other gamefish line up when spillway gates open. Keep an eye on the spillways; when the water is flowing the fish won't be far behind.
