Rock Lake is near the middle of the town of Aztalan two miles and three quarters long, one mile and a quarter wide and covers an area of sixteen hundred and fifty three acres, or a little over two and a half sections. Its name is derived from the unusual number of rocks along the shore thrown up by the expansion of ice in water into a ridge in many places several feet in height. It discharges its waters through a small stream in a north easterly direction into the West Branch. The shores of this lake are high and present a beautiful propect to the eye.

At the outlet of this lake a water power has been created; mills erected, and a small village called Kyesville has sprung up within the last year or two.
