In 1853, Edmond Jefferies filed a claim on thirty acres using his squatter's rights. Through the next fourteen years his land increased to seventy-eight acres and then to two thousand acres. In 1877, an ice gorge and unusually large spring runoff flooded the river thus creating Cut-Off Lake. In 1906, Cut-Off Lake became Lake Nakoma, after Peter Sarpy's Native American wife. The lake changed its name for the final time in 1908 to Carter Lake after Selina Carter-Cornish had donated some of land owned by her late husband, Levi Carter. From 1892 to 1912 Courtland Beach was a resort on the lake used by many wealthy Omahans. The resort included a pavilion, ballroom, and the boating club. World War I hero, Eddie Richenbacher won at the race track in Carter Lake averaging over 91.7 miles per hour. Eddie later went on to own the Indianapolis 500.
