The process to change a name is the same. However, a name that has existed for 40 years or more may not be changed. Also, the commissioner of natural resources will not approve a name that commemorates, or may be construed to commemorate, living persons. When swimming, one might notice colder, localized areas or areas of the lake might remain open along the shoreline during winter. Both are likely due to ground water flowing into the lake.
Lakes also lose water to ground water sources.
Variations in precipitation patterns can cause the amount in or out to change significantly. Generally, complex hydrologic computer models including information such as watershed, geology, precipitation, lake level, and ground water level data are used to estimate how much is flowing in or out of the lake. A meander line is a series of courses and distances to delineate the area of a body of water. It is not a boundary line, nor does it convey land ownership information. For lakes and wetlands, the OHW is the highest water level that has been maintained for a sufficient period of time to leave evidence upon the landscape.
