LE SUEUK COUNTY. 533 



Natural drainage. Lakes.] 



Derrynane; a small creek, about seven miles long, which flows from Clark's lake in Scott county 

 southerly into Tyrone and enters the Minnesota at East Henderson; and Sand creek, which drains 

 the north part of Derrynane, all of Lanesburg except its southwest corner, and the northeast 

 part of Montgomery, lakes Pepin and Sanborn, and Hunt lake, in the two last named townships, 

 at the head of this stream, being sixteen to eighteen miles in a straight line from its mouth, 

 which is two miles north of Jordan in Scott county. 



The highest sources of the Cannon river are several lakes in Shieldsville, Eice county, 

 whence this stream flows westerly twelve miles, crossing Kilkenny, receiving the overflow of 

 lakes Dora and Volney, and entering lake Gorman at Cordova. Next its course is southerly eight 

 miles, passing through Saber lake in section 30, Kilkenny, and entering the west part of lake Te- 

 tonka in Waterville. Above Saber lake this is called Big Cannon river, to distinguisli it from a 

 smaller stream, known as Little Cannon river, which flows into Saber lake from the east. About 

 a mile above its mouth into Lake Tetonka, this river receives a tributary from the west, which is 

 the outlet of lake Bossuot in sections 29, 32 and 33, Cordova, and of German and other lakes in 

 the north part of Elysian. In Waterville the Cannon river flows through lakes Tetonka and Sa- 

 kata, which together extend from the west to the east line of this township, being connected by 

 a stream only about a quarter of a mile long. A considerable creek, whose basin extends into 

 northern Waseca county, enters the west part of lake Sakata. The townships of Le Sueur county 

 which are partly or wholly drained by the Cannon river are Waterville, excepting perhaps half a 

 section in its southwest corner, the northeast half of Elysian, the southeast half of Cordova, all 

 of Kilkenny, and the southern third of Montgomery. 



Lakes. Among the lakes of Le Sueur county the following deserve mention: lake Jefferson, 

 lying principally in Washington and the northwest corner of Elysian, five miles long from east to 

 west and from an eighth to two-thirds of a mile wide, very crooked, with an arm or branch on the 

 south about two miles long; lake Washington, also of quite irregular form, having an area 

 of about two and a half square miles, lying mostly in the southwest part of Washington; lake 

 Emily, mainly in section 26, Kasota, two miles east of Saint Peter, similarly irregular in outlines, 

 but only a little more than a mile long, very picturesque, bordered partly by woods, but mostly 

 by fertile and well cultivated farms, its west end being near the verge of the bluff which descends 

 two hundred feet from this lake to the bottomland of the Minnesota valley; Scotch lake, one and 

 a half miles long from east to west, in sections 22 and 23, Cleveland; Clear lake, three-fourths of a 

 mile in diameter, in section 10, Lexington; lake Pepin and lake Sanborn, each about a mile long, 

 in Lanesburg; lake Dora, nearly two miles long from northwest to southeast, in the north part of 

 Kilkenny; lake Gorman, one and a quarter miles long from north to south, and from a half mile to 

 one mile wide, lying mostly in sections 12 and 13, Cordova; German lake, covering about a thou- 

 sand acres, mainly in sections 4 and 5, Elysian, and lake Francis, three miles long from east to 

 west, in the south part of this township: lake Elysian, whose north end is crossed by the south line 

 of the county at the south side of sections 35 and 36, Elysian; and lake Tetonka, four miles long 

 from west to east and averaging a half mile in width, lying mostly in sections 19, 20, 21 and 22, 

 Waterville, and lake Sakata, about three miles long and also averaging a half mile wide, extending 

 eastward from Waterville and reaching into Rice county. 



Topography. The terminal moraine accumulated on the east side of 

 the Minnesota lobe of the last ice-sheet, consisting of hills, mounds and 

 ridges of till, occupies the east edge of Le Sueur county and the adjoining 

 western half of Rice county. Its west border extends from near the north- 

 east corner of Le Sueur county southward by lake Sanborn, Montgomery, 

 Greenleaf lake, lake Volney and Saber lake, to Waterville. The hills of 

 this tract, constituting the highest part of the county, are 50 to 75 feet 

 above the intervening depressions, or from 1100 to 1125 feet above the sea. 

 In Montgomery and Kilkenny they are principally massive swells with
