Drop Shot 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.
The drop shot suspends a soft plastic bait above the bottom on a fixed line, keeping it in the strike zone longer than any other rig. Originally a West Coast technique, it now dominates clear-water and finesse situations nationwide. Works vertically over structure or on a long cast.

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.
Drop Shot: Target staging fish on points and drop-offs in 8–20 feet. Nose-hook a 6" Roboworm or Berkley PowerBait MaxScent Flat Worm.
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.
Drop Shot: Go deep — 20–40 feet on main lake structure. Shake in place with minimal movement. Shad colors dominate.
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.
Drop Shot: Follow baitfish to secondary points and pockets. Faster retrieve works as fish get more aggressive.
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.
Drop Shot: Slowest presentation of the year. Dead-stick a 4" finesse worm at the bottom. Let it sit 10–15 seconds between shakes.
Best Conditions
Clear to stained water, pressured fish, cold fronts, post-spawn suspended bass, deep structure in summer
Use a Palomar knot and leave the tag end pointing up to keep the hook riding correctly. Most anglers tie it wrong.
