When bass fishermen think about topwater action, they think of warm summer mornings when the fog is lifting, or rainy fall days when bass are putting the final feed bag on before winter. I think early spring, and I think about creeks, drains, and super shallow runoff pockets. Naturally, bass may not be tuned into something like a buzzbait the second they come shallow early in the season, but give them a week of above average temps, then a warm rain to top it off, and the buzzbait can be money at any point where that heated runoff is dumping into the lake or river. Figuring out if you’re in a prime spring topwater zone is all about watching your water temp gauge when you enter creeks. An uptick of a few degrees is good, but if you find a creek that’s ten or more degrees warmer than the main body, start buzzing.
