Canaseraga Creek Improvement 



It is the intention to complete construction work on this im- 

 portant improvement during 1914. 



The work as designed requires thirty-four miles of improved 

 and new channels, provided approximately as follows: 



Mile 



Canaseraga creek 15 



Keshequa creek 2 



State ditch 5% 



Bradner creek 7% 



West Mud run 2 



East Mud run 1% 



A number of new highway and farm bridges, and other inci- 

 dental work, are included in the improvement. 



The greatest flood in the history of the Canaseraga valley oc- 

 curred in the early spring of 1913. The Genesee river at its 

 junction with the Canaseraga creek rose to the highest elevation 

 on record, or possibly seven inches higher than ever formerly 

 recorded. The elevation of the flood at said junction was 568.6 

 above tide, U. S. G. S. datum. This high flood caused, back water 

 as far south or up stream as Groveland. From a point about one 

 mile north of Cumminsville the valley generally was overflowed 

 for a short time all the way down stream to near Groveland, there 

 meeting the back water effects from the Genesee river. 



South of Cumminsville and entirely outside of the Canaseraga 

 Creek Improvement District, the Canaseraga creek burst its 

 natural bounds and artificial banks, and the flood waters caused 

 considerable damage at Cumminsville and in the valley up stream 

 therefrom for a distance of about one mile to the southward. The 

 town of Groveland appropriated a sum sufficient, and from the 

 proceeds has constructed dikes, pile, timber and brush protection, 

 and excavated some enlargement to the natural channel, and seem- 

 ingly completed the same in a good and workmanlike maimer. 

 It is believed that this protection will prevent further flood dam- 

 age at and south of Cumminsville for many years to come.
