How to use this ranking
The order is a map-planning ranking, not a claim about today's fish population. It favors larger mapped waters and gives survey-backed contours a three-times data-quality boost. Agency population surveys, current regulations, access and recent conditions should make the final decision.

When to fish splake in Colorado
- Spring 5–25 ft — Ice-out through spring, splake patrol shoreline rock, points and inflows like oversized brookies.
- Summer 25–60 ft — Warm water pushes splake below the thermocline — deep breaks and humps, shallower than lakers in the same lake.
- Fall 10–35 ft — Mostly sterile but still hormone-driven — fall splake stage on rock shoals and points and eat aggressively.
- Winter 10–45 ft — Why they're stocked: an active, roaming winter predator — work basin edges and mid-depth humps, and hole-hop.
