Schoharie creek about 9000 horsepower. As to whether the power 

 is to be 10 hour. 12 hour or 24 hour power will also be taken 

 into account. There is, however, some doubt as to whether it is 

 possible to make a storage large enough to secure a flow of Got) 

 cubic feet per second, and until thorough surveys are made this 

 must be considered merely a possibility. In view of this uncer- 

 tainty and doubt, it is considered safer to assume that not more 

 than 5000 to 6000 permanent power can be developed within 

 commercial limits. 



The dam at Schoharie falls is of masonry, backed with 

 timber. It was originally constructed with crest 380 feet long, 

 but in the spring of 1901, in a heavy flood, a portion of the 

 dam and canal was carried away. Damage to the canal was 

 due to inadequate wasteway arrangements — the wasteway origi- 

 nally constructed being only 50 feet in length. Owing to 

 financial difficulties this dam was not repaired until 1902, at 

 which time the cost of repairing it and the raceway and the 

 making of the necessary repairs to power station was estimated 

 at |80,000 — the actual cost was somewhat more than this. 

 In the repairs, the dam was made 620 feet in length and the waste- 

 way 100 feet in length. It is understood that in the fall of 1903 

 the dam was again carried away by floods and that it has not 

 yet been rebuilt. Owing to these unexpected expenditures the 

 company is in financial difficulties and it is uncertain whether 

 the dam is likely to be repaired. 



Power Development on West Canada Creek 



The Utica Gas & Electric Company. In 1901-2 a power plant 

 was constructed at Trenton Falls by the Utica Gas & Electric 

 Company. The following are some of the particulars of this plant, 

 as derived from a letter from C. A. Greenidge, superintendent of 

 the electrical department of that company, dated April 6, 1901 : 



This plant includes a concrete dam, with hight above the bed 

 of the stream of 60 feet and 55 feet thick at the base; 288 feet 

 long and arched upstream on a radius of 800 feet. It is con- 

 structed of concrete, partly faced with stone. In its center there 

 is a spillway 100 feet wide and on the right, cut in the rock face 

 of the gorge, another spillway 112 feet wide. At a depth of 10 

 feet below the surface of the pond there are four 60-inch supply
