Green Lake and Round Lake are two of a few lakes in the US that are meromictic. There is no spring or fall turnover as occurs in most lakes, so the surface water of meromictic lakes does not mix with the bottom water.


The lakes are excellent for paddling and kayaking, and the hiking and birding trails are unique.
 

Birds Likely Seen: American goldfinches, robins and other thrushes, various types of warblers, woodpeckers, sparrows, whitebreasted nuthatches, chickadees, titmice, indigo buntings, scarlet tanagers, northern orioles.


A Hippocampe Beach/All Terrain wheelchair is now available at Green Lakes State Park to access beach and trails. The wheelchair is available for use at no charge on a first come, first serve basis from 11am-7pm.
