When do you throw top water for muskies in rivers?

Answer:

Any temp can be good for topwater. River fish are typically suckers for topwater (they like suckers too). Even though topwater baits are normally most productive in the summer and early fall, spring is the most underrated time-frame for them. You needn’t wait for the little duckies to hatch. Types vary, but in general, louder, larger presentations work better in high current, waves and roiled up water.
