Bloomstrom Reservoir Fishing in Tripp County, South Dakota

• Overview

  Bloomstrom Reservoir stands in Tripp County, South Dakota. Beyond the shoreline you have rolling bush. Small at around 4 acres: two anglers spread out cover most of it. The town to know is Gregory, 21 miles out. Further out sit Winner (27 miles) and Ainsworth (32 miles). It sits well inside its county, with no border complications.

• Where to Fish on Bloomstrom Reservoir

  We hold no depth figure for this one. The old creek line under the surface is the feature worth finding. A reservoir gives you a hard edge, a shelf, and not much else. County-wide records name Iowa darter, green sunfish, largemouth bass and black bullhead. What holds for the county may not hold for this water. Anyone new to Bloomstrom Reservoir should walk it once before setting up.

• Seasonal Patterns

  Seasonal averages run from 21°F in January up to 75°F in July. Winter shuts things down for a spell, then spring reopens them fast. The open season starts with the thaw, near enough late March. Climate averages put the opening at about late March and the closing near early December. Just after the ice goes and just before it returns, the fishing lifts. Bloomstrom Reservoir runs to that rhythm year in and year out.

• Tackle & Baits

  Nothing in our records says who may fish here. The map shows no ramp or car park nearby, so this is a walk-in water. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Parking space is the usual limit rather than the bank itself. Some ground is open by custom rather than by right, so tread carefully. Kappleman Reservoir sits 2.2 miles off and takes the overflow. Nothing here settles the position at Bloomstrom Reservoir for certain.
