Lake Ambrose Fishing near Fort Thompson, South Dakota

• Overview

  Lake Ambrose belongs to Hyde County, South Dakota. The ground around here is pine and birch. The water covers some 34 acres, so pick a bank rather than trying to cover it all. It is one of the smaller waters we list in Hyde County. The town to know is Fort Thompson, 13 miles out. Sioux Falls sits 144 miles out, and it is the nearest city worth the name. It lies deep inside the county rather than near an edge.

• Where to Fish on Lake Ambrose

  Depth is not on record here, which means reading the ground instead. Bays and points beat straight shoreline every time on water like this. Look for the band where the shallows give up and the bottom falls away. Public occurrence data for Hyde County names common carp and largemouth bass. What holds for the county may not hold for this water. Lake Ambrose gives up its fish to patience rather than distance.

• Seasonal Patterns

  The range across the year is 14°F to 73°F. Spring and autumn carry the fishing; summer and winter test it. Expect a solid lid for months and a thaw around early April. Going by climate averages, expect open water from about early April until roughly late November. September and October fish steadily right up to the freeze. Expect Lake Ambrose to follow that timing.

• Tackle & Baits

  Public sources are silent on who controls the bank. You can leave the car about half a mile from the water. A small crankbait along the drop and a worm in the thick stuff cover the bass. Read any posted signs at the access point rather than assuming. Check whether bait restrictions apply before you buy any. Lake Boehm at 2.2 miles is the sensible second choice.
