 ply to be drawn through Moose Lake 

 surplus, affording a flowage of 791^ 



cubic feet of water per second for 

 ninety day; the cost of this dam, $55,- 

 511.70. 



Eleventh site, at Lac Courtes Oreilles ; 

 a dam five feet high and 260 feet 

 long will produce a reservoir of 1,981,- 

 331,000 cubic feet capacity, furnishing 

 flowage of 255.44 cubic feet of water 

 per second for ninety days. 



Twelfth site, on the Chippewa River, 

 below the mouth of Paint Creek ; a dam 

 twenty-two feet high, 620 feet long, 

 will create a reservoir with capacity of 

 508,336,720 cubic feet, to cost $60,000. 



The foregoing, summarized from 

 Major Allen's report of 1880, shows the 

 result of an incomplete survey and ex- 

 amination of the Chippewa River and 

 branches above the city of Chippewa 

 Falls. It may be safely stated that a 

 complete examination would result in 

 the discovery of eligible sites for res- 

 ervoirs equaling in capacity the above- 

 described. It is significant to note fiu"- 

 ther that two large tributaries flowing 

 into the Chippewa below Chippewa 

 Falls, to wit, the Eau Claire and Red 

 Cedar, are omitted, the improvement of 

 which would be more valuable to navi- 

 gation from Eau Claire City to the 

 Mississippi. 



Summing up the results of this in- 

 complete examination, the major states 

 that, as a result of the reservoirs named, 

 ''2,800 cubic feet per second for ninety 

 days would be added to the normal low- 

 water discharges of the stream." The 

 low-water discharge of the Chippewa 

 River at the mouth or at the jetties may 

 be taken at about 2,600 cubic feet per 

 second and about 3,400 cubic feet above 

 the entrance of Beef Slough. flJeef 

 Slough is now closed, adding 800 cubic 

 feet at the mouth of the river.) When 

 4,000 cubic feet per second pass through 

 the jetties good navigation obtains from 

 the mouth to Eau Claire. Adding the 

 increase (2,800 cubic feet) to the 2,600 

 cubic feet at the mouth, we have at 

 least 5,400 cubic feet for ninety days, 

 or 1,400 cubic feet more than abso- 

 lutely required for purposes of naviga- 

 tion. To these may be added 800 cu- 

 bic feet formerly diverted through Beef 

 Slough.
