• Where to Fish on Blunn Reservoir

  Depth here is unknown, so count the lead down before committing. Points where the flooded channel swings in are the reliable ones. Look for where the old bank line still shows under the surface. Across Jefferson County, recorded fish include rainbow trout, brown trout, common carp and green sunfish. It is the county picture; the agency list is water-specific. The shape of Blunn Reservoir decides where the fish sit.

• Seasonal Patterns

  Between January at about 31°F and July at about 71°F, the water has a wide range to work through. Fishing continues through most of the calendar, with quiet spells rather than closures. In milder years the edges alone go, and the middle never sets. March through May is the strongest run, with October and November a second stretch. Time your trip to Blunn Reservoir by conditions rather than dates.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. Mapping marks this water as fished, so there is at least an established use. Public data records a boat ramp half a mile out. Mapping shows a jetty some half a mile off. For the trout, small spinners and a box of nymphs cover both approaches. Season dates differ by species, so read the table. Fishing rules and camping rules are set separately here. Tucker Lake, 0.7 miles away, makes the obvious fallback. Nothing on Blunn Reservoir should be assumed from this page alone.
