 | | The outlet elevation between the upstream lakes (Hillebrands Lake, Rush Lake, Spring Lake, Swan Pond, and Waubay Lake) and Bitter Lake was changed from an elevation of 1,803.6 feet to 1,798.69 feet to reflect the modified outlet between Rush and Bitter Lakes. |
 | | The unconditional frequency analysis was performed for Bitter, Enemy Swim, Pickerel, and Waubay Lakes using 10,000 years of generated lake levels with the farm crossings removed at the outlet between Rush and Bitter Lakes. |
 | | Bitter Lake exceeded an elevation of 1,814.0 ft, which is high enough to result in large flows to the Big Sioux River, an average of once every 2,500 years and stayed above this elevation an average of 5 years before subsiding. |
