Is West Okoboji Lake full?

West Okoboji is a natural glacial lake, part of the Iowa Great Lakes, so it has no full pool. The chain of lakes drains to the Little Sioux River over a small outlet dam, but nothing holds the lake at a fixed level; the page compares the level with past years and with the National Weather Service flood stage (1,398.2 ft, 6.5 ft on the gage). It is 0.42 ft higher than a year ago (1,395.50 ft on Nov 9, 2025).
