 and thence westerly to the Niagara river at Tonawanda, at which 

 place its chief tributary, Ellicott creek, joins the main stream. 

 For the first thirty miles of its flow the creek drains hilly and 

 rolling country, having a sharp descent. Its extreme headwaters 

 in Wyoming county are at an elevation of about 1200 feet. _ From 

 Batavia to Tonawanda, a distance of nearly sixty miles by the 

 stream, the topography is flat, having a total fall between these 

 points of about 310 feet. A considerable portion of the catch 

 ment area of this section is not only fiat and marshy, but also 

 narrow. Between Batavia and Tonawanda the creek has been 

 modified by two artificial interruptions: (1), by the diversion of 

 a portion of its water through a diversion channel into Oak 

 Orchard creek, from which water is drawn to the Erie canal at 

 Medina; and (2), at Tonawanda the creek is artificially raised by 

 the State dam and the stream canalized and used as a part of 

 Erie canal for a distance of twelve miles to Pendleton. The major 

 portion of the water supply of the western division of the Erie 

 canal is drawn from Lake Erie through this canalized portion of
