Search for Historical Lake Levels in South Dakota
The surface elevation for many South Dakota lakes is measured each spring and fall. Please note that these biannual measurements are not indicative of any annual high or low water levels. The measurements only reflect the level of the lake on the day the measurement was recorded. In addition to your search returning surface elevations, some lakes have an elevation established for the ordinary high/low water mark and lake outlet which will be included in your search results.

Every lake in South Dakota has had an ordinary high and low water mark and outlet established through natural processes (precipitation, wave action, vegetation, erosion, etc.) which, in some cases, have been influenced by man-made activities as well. However, the official numeric elevation of an ordinary high/low water mark and lake outlet is established by the state Water Management Board. Some South Dakota lakes have these official elevations established and many do not. When searching for a lake using the above search tool, any official elevations established by the Water Management Board will be listed in the search results.
State law provides that all navigable rivers and lakes are public highways within 50 feet landward from the water's edge, provided the outer boundary does not expand beyond the ordinary high water mark or contract within the ordinary low water mark. An exception exists for all lakes with ordinary high water marks established by the board prior to 1985. For these lakes the public highway exists from the water's edge or ordinary low water mark to the ordinary high water mark. While the public may use this strip of land for public purposes, the private adjoining landowner may also use the land for any purpose that is not inconsistent with the rights of the public. For example, the adjoining landowner may exercise the right to graze and water livestock, to cut hay, or build a boat dock.
