Jig (Casting & Pitching) 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 lead or tungsten head with a weed guard, skirt, and soft plastic trailer. Fished on the bottom by pitching, casting, or slow-rolling. The jig imitates crawfish and bottom-dwelling forage. More big bass have been caught on jigs than any other lure category — it's the lure that separates serious anglers.

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.
Jig (Casting & Pitching): Pre-spawn is prime season — pitch brown/green pumpkin jig to 45° bank transitions and rocky points.
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.
Jig (Casting & Pitching): Football jig on offshore ledges 15–30 feet. Swimming jig around grass edges at dawn.
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.
Jig (Casting & Pitching): Swim a jig around baitfish schools near points and flats. Shad trailer colors 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.
Jig (Casting & Pitching): Slowest presentation — drag a 3/8 oz football jig on deep hard bottom. Barely move it.
Best Conditions
All seasons, all depths, all cover types; most effective in 50–70°F water; excellent in pre-spawn and when fish are on hard bottom
Match trailer to conditions: craw trailer in cold water (slower fall, bigger profile), swimbait trailer when swimming, chunk trailer for flipping.
