Topwater Popper Fishing on Chatfield Reservoir
Chatfield Reservoir · Colorado · West
Chatfield Reservoir sits at roughly 5,430 feet elevation in the South Platte River drainage, impounded by the Army Corps of Engineers for flood control — which means water levels can swing dramatically, especially in late summer and fall. The fishery mixes shallow cove structure, submerged vegetation, riprap margins, and open flats, with largemouth bass as the primary draw alongside walleye, wipers, and catfish. Water clarity trends clearer than most Front Range urban lakes but can turn turbid quickly after spring runoff or heavy rain events on the watershed.
A floating hard bait with a concave face that produces a spitting, popping action when twitched. Most effective in low-light conditions near cover — points, dock edges, weed lines, and grass pockets. The pause after the pop is where most strikes happen. Few experiences in fishing match watching a largemouth explode on a popper.

Seasonal Tactics on Chatfield Reservoir
Lake: Pre-spawn largemouth push into the shallow coves and riprap-lined arms as water temps climb through the mid-50s into low 60s, typically late April through May. Slow-rolled swimbaits and 3/8 oz Strike King Hack Attack jigs along the 3–6 ft transition are productive before fish commit to beds.
Topwater Popper: First light on spawning flats — fish hold shallow and crush surface baits. Slow cadence with long pauses.
Lake: Post-spawn bass scatter to submerged vegetation edges and deeper flat structure in 8–15 ft; topwater action on main-lake points fires up in low-light windows during July and August when surface temps crest 75 degrees. Evening wacky-rig sessions in the back of coves can be surprisingly consistent on pressured fish.
Topwater Popper: 30-minute window at dawn and dusk. Fish dock shade and grass pockets. Noon topwater dies.
Lake: Water-level drawdowns by the Corps in late September and October concentrate bass on shrinking structure, particularly along the old river channel edges and points closest to the dam. Shad-imitating crankbaits like the Strike King Series 3 in sexy shad excel as baitfish stack up before the cold sets in.
Topwater Popper: Extended feeding window as water cools. Fish can be caught on top all day in fall.
Lake: Chatfield stays open year-round and draws ice-fishing pressure in hard winters, but open-water bass fishing slows significantly below 45 degrees. Drop-shot rigs with 4-inch Roboworm Straight Tail worms in oxblood or morning dawn, fished painfully slow on deeper flats in 15–20 ft, account for most cold-season bass.
Topwater Popper: Generally ineffective in water below 55°F — bass won't chase topwater in cold conditions.
Best Conditions
Dawn and dusk year-round, overcast days, calm to light-chop surface, spring through fall near cover and grass edges
Don't set the hook on the explosion — wait until you feel the fish pull the line. Half of all missed popper strikes are from anglers jerking too early.
