oue and oiie-lialf miles wide, having an area of nearly 1,900 aci-es. The 

 surface of the lake is about 735 feet above tide. It is 150 feet above 

 Lake Michigan, but 130 feet below the summit of the divide between 

 Lake Michigan and the Wabash River. The lake is 15 feet above the 

 Tippecanoe River five miles south, and aliout 75 feet above English 

 Lake, 20 miles west. These elevations show that the lake is on a slope 

 That descends gently toward the south and west. The lake is near the 

 southwestern angle of the Saginaw moraine. The country about the 

 lake is quite varied. There are hills and valleys, broad undulating- 

 plateaus, wet marshes and boggy swamps. The soils are sand, gravel, 

 boulder, clay and swamp muck. There are more hills and clay and 

 boulders on the east, more sand and gravel, more marshes and swamps 

 on the west. On the east the surface rises somewhat abruptly to a 

 general level of 75 or 80 feet above the lake, some hills reaching an 

 elevation of about 140 feet. On the west there is a narrow divide 25 

 to 30 feet above the lake, then low land and swamp. The confused 

 mingling of sand, gravel, clay and boulders, the in-egular hills and the 

 numerous kettle holes indicate that the surface features about the lake 

 are of glacial origin. .Just east of the center of the lake there are 15 

 or 20 acres of Avater that is from 85 to 90 feet deep. This deepest water is 

 part of some 300 acres of deep water that forms the central portion of 

 the lake. Fully one-half the area of the lake is shallow, the water being 

 ten feet or less in depth. 



Wells drilled from 75 to 150 feet through sand, gravel and clay, 

 without reaching bed rock, indicate that the lake bed is wholly composed 

 of morainic matei'ials. In fact it seems to occupy a cluster of kettle holes, 

 one long and deep, surrounded by several of lesser size and depth. The 

 region drained into the lake is quite limited, being searcely more than 

 three times its area. "The Inlet" enters the lake from the southeast. 

 Aubeenauliee Creek from the east, and Culver Inlet, with one branch 

 from the north and oue from the east, enters the northeastern part of 

 the lake. These four streams, each rising within two miles of the lake, 

 each largely fed by springs, are the pi-incipal inlets. Several very small 

 streams, the outlets of springs, bogs, flowing wells and little swamps, 

 conti-ibute something to the waters of the lake. "The Outlet" is a slug- 

 gish stream which flows from the west side of the lake southerly into 

 the Tippecanoe River. About 80 rods from the lake the outlet expands 

 into a pond or lake, having an area of about 60 acres. This bodv of
