John Martin Reservoir

Where it is

John Martin Reservoir sits in Bent County, Colorado, covering about 11,685 acres. Largemouth use the shallow cover and the deeper water as the calendar moves.

Seasonal pattern

Spring. Early warming sends largemouth into the shallows to stage and spawn, the calmest sun-fed water leading the move.

Summer. Warm water moves largemouth onto deeper structure and shade; the early and late hours are the better windows.

Fall. Dropping temperatures pull bait and largemouth back toward shallow water in a wider, roaming feed.

Winter. In cold water fish hold deep and inactive; ease off the pace and keep presentations quiet.

Key structure

• Transitions from soft to hard bottom
• Shoreline cover near quick depth changes
• Shade lines and overhead cover in the warm months
• Submerged wood, brush, and laydown cover

Let the season pick the water before any one spot does.
