Everything in fishing changes. On the minutest level, that change can be as simple as fish suddenly turning off of green-pumpkin worms after they’d been hammering them for hours, or a slow bite suddenly going bonkers before a storm. In the grander scheme, what can also change is the overall quality of an entire fishery. Sometimes lakes or rivers that were hot for decades suddenly go cold. It can happen for any number of reasons. On the contrary, removal of dams, a revival of water quality, or a regulation change can revive a struggling fishery or turn what was a little-known body of water into a big-time destination. To get the most up-to-date skinny on which bodies of water are trending now, we reached out to biologists, conservation officers, guides, pros, and local sharpies in every state. Here are their picks.
