Lake Sakakawea is formed by the completion of Garrison Dam across the Missouri River in 1956. The resulting reservoir is the third largest in the United States.
I only had time for a few stops along the northwestern end of the lake near Four Bears Bridge and New Town. Again, it was a terrible day for photography (too bright and too much haze), so I will need to visit the lake again on future trips.
Oil development is common along the edge of the lake, with some rigs drilling new wells right on the shore in some locations. This appears to put this important source of agricultural and drinking water at risk from oil and/or waste water spills.
