Carolina Rig Fishing on John Martin Reservoir
John Martin Reservoir · Colorado · West
John Martin Reservoir is a large, scenic impoundment located in Bent County, Colorado, featuring numerous coves, submerged structure, and rocky shorelines that hold largemouth and smallmouth bass. The reservoir's elevation of 3,630 feet and varied terrain create diverse habitat zones that support consistent bass populations throughout the year. This high plains reservoir is popular with regional anglers for its combination of accessible fishing and good catch rates.
A 3/4–1 oz bullet or egg sinker rides on the main line ahead of a barrel swivel, followed by an 18–24 inch fluorocarbon leader and weedless soft plastic. The weight thumps the bottom and stirs up silt while the bait floats up and glides naturally. Exceptional for covering points, humps, and offshore structure quickly.

Seasonal Tactics on John Martin Reservoir
Lake: Spring brings aggressive feeding as bass move to shallow coves and spawning areas near main lake creek channels. Crankbaits, spinnerbaits, and topwater lures produce well as water temperatures warm into the 50s and 60s.
Carolina Rig: Post-spawn fish pulled off beds to first break lines. Lizards and big creature baits.
Lake: Summer bass retreat to deeper structure, main lake points, and rocky ledges where cooler water provides relief. Offshore fishing with drop shots, Carolina rigs, and deep-diving crankbaits near the dam and creek channels becomes most effective.
Carolina Rig: Primary technique on main lake ledges and offshore humps in 15–30 feet. Slow drag and pause.
Lake: Fall migration patterns push bass into mid-depth zones and along the main creek channel where baitfish congregate. Shad-pattern crankbaits, swimbaits, and soft plastics work well as bass feed heavily before winter.
Carolina Rig: Shad-imitating plastics on transitional structure as fish chase baitfish migrations.
Lake: Winter bass slow considerably but remain catchable near deeper holes and the main channel. Slow presentations with jigging spoons, drop shots, and small soft plastics near structure produce the most consistent results in cold water.
Carolina Rig: Slower retrieve, smaller plastic (4" straight worm). Fish it like a drop shot you drag.
Best Conditions
Post-spawn and summer offshore structure, points, humps, ledges; stained to clear water; when fish are scattered
Add a glass bead between the weight and swivel — the click mimics crawfish and triggers reaction strikes, especially on hard bottom.
