“And God remembered Noah, and every living thing, and all the cattle that was with him in the ark: and God made a wind to pass over the earth, and the waters asswaged;”“The fountains also of the deep and the windows of heaven were stopped, and the rain from heaven was restrained;”“And the waters returned from off the earth continually: and after the end of the hundred and fifty days the waters were abated.”“And the ark rested in the seventh month, on the seventeenth day of the month, upon the mountains of Ararat.”“And the waters decreased continually until the tenth month: in the tenth month, on the first day of the month, were the tops of the mountains seen.”“And it came to pass at the end of forty days, that Noah opened the window of the ark which he had made:”“And he sent forth a raven, which went forth to and fro, until the waters were dried up from off the earth.” “Also he sent forth a dove from him, to see if the waters were abated from off the face of the ground;”“But the dove found no rest for the sole of her foot, and she returned unto him into the ark, for the waters were on the face of the whole earth: then he put forth his hand, and took her, and pulled her in unto him into the ark.”

Rock Lake is in south central Wisconsin, at Lake Mills, Wisconsin in Jefferson County, Wisconsin approximately 20 miles (32 km) east of Madison. Rock Lake is a 1365-acre lake with a maximum depth of 60 feet (18.3 m).[1]
The lake shape resembles a slight figure eight with several distinct areas. South of the figure eight portion of the lake lies Bean Lake State natural area which is a protected marsh. Part of the south western part of the figure eight is usually covered in tall aquatic vegetation that reach out of the water. In the north western portion of the figure eight there is a sand bar which often has boats anchored and is swimming accessible.
The Glacial Drumlin State Trail[2] runs across an old rail road bridge across the southern portion of the lake. The trail separates the lake from the marsh area to the south of the lake.

The Glacial Drumlin State Trail is a multipurpose rail trail in the U.S. State of Wisconsin. It stretches 52 miles (84 km) from Waukesha (near Milwaukee) to Cottage Grove (near Madison).[1] The trail travels through or near the Wisconsin communities of Cottage Grove, Deerfield, London, Lake Mills, Jefferson, Helenville, Sullivan, Dousman, Genesee, Wales, and Waukesha.[2] In Lake Mills, it crosses Rock Lake on one of its many old railroad bridges. The trail was opened in 1986 and follows the old Chicago and North Western Railway (C&NW) Madison–Milwaukee mainline.[3]
