.. GENERAL ENGINEERING COMPANY. INC. 2 - April 26, 1976 Pia c, Attorneys Dykman, Hanson, Richter, Molbreak, Schneider, Birkeland, Weber TO: and Bannen . Re: Edward F. Bozelka, et al , Vs. Town of Dunn, et al , and Eleanore Bozelka Dane County Circuit Court Case No. 144-045 Engineer's Preliminary Report - File No. 1275-145 The area is on the west side of Lake Kegonsa where approximately 200 acres of watershed drains into Lake Kegonsa just southerly from Collady Point . T1,0 draio:.0e area has steep slopes with a rise of avlroxina • l I eet _ •lip ve the lake in a distance of less than a mile. The mouth of the drainage area where it reaches the lake is approximately 1500 feet long but most of the flow occurs over a much shorter length of shoreline. There is very little water storage area in the drainage shed and the soil is relatively tight so that surface waters are not readily absorbed. 1*pSa Much of the drainage area is in fields; many of which are not contoured. !.1 These cGi fl tions all contribute toward a rapid run-off of surface waters that 11‘f pick up and carry a substantial amount of silt and brown color. The effects of man's encroachment on nature in the normal course of, develop- ment can be observed in: 1. Farming operations • 2. Construction of roads and bridges . 3. Filling of lowlands • 4. Construction of buildings S. Construction of sea walls all of which effect the run-off. Culverts under C.T.H. "B", tlyreson Rd. , USII 51 and Colladay Drive, together with the road fills through the lower areas, tend to concentrate the surface water flows into a channel and in some cases, back up the water to flood certain lands. l " _ ..,,•---- .1.1.1.1..-. ........ . ...a...�.401..4......-«+�r+�wi.�s... .+.e.,.v......r.t There are many property owners in the drainage basin; therefore, no one person has control of it. �' ' ...n.1.. . s ..,__.....:.r r�.ra .a-•w-....._. ..,_. .w.... the I :in : moll ; the shoreline wa'; relatively flat and, as hor.ec have been con- structed in that area, there has been some filling of land causing surface waters to be diverted around the fill. As adjacent lots were improved and more fills were placed, further diversions occurred. The filling therefore was not solving any problems but simply shifted them to a different location.
