Solid cloud cover today, with a whisper of wind from the SW and pressure sitting still. Most of the action on Bismark Lake should come off windblown banks where food collects. The day holds up well from the day. Work the productive water thoroughly. Cooler water spreads fish back across the shallows.

Bismark Lake belongs to Custer County, South Dakota. The bank is 5,207 feet above sea level. Small at around 22 acres: two anglers spread out cover most of it. Compared with other South Dakota water on our list, it sits high. Supplies mean a trip to Custer, 4.2 miles off. Colonial Pine Hills lies 19 miles off, Hot Springs another 24 miles. A county boundary sits nearby, which can matter for local access rules.
Depth here is unknown, so count the lead down before committing. Held water runs deepest at the wall and shallows back to the inflow. The old creek line under the surface is the feature worth finding. Public occurrence data for Custer County names rainbow trout, brook trout and bluegill. The county figures include rivers and lakes alike. On Bismark Lake the obvious spot is not always the productive one.
Long-term averages put July at about 66°F and January near 23°F. Winter shuts the surface down for months. After early April the shallows warm and the fish move up. The water is typically free of ice between early April and early December. Spring is short and heavy here; autumn is longer and steadier. Plan any trip to Bismark Lake around it.
Nothing we hold confirms whether access is permitted. A boat ramp sits about half a mile from the water. There is a car park half a mile from the bank. There is a mapped landing stage half a mile away. A campsite lies half a mile away for anyone staying over. A toilet block sits 160 yards away. Where a permit is needed, the nearest town usually sells it. Some stretches are reserved and marked as such on the ground. Failing this one, try Stockade Lake, 0.6 miles away. The position on Bismark Lake is worth confirming on the day.
