The plan here considered will increase the drainage area tributary to the Hemlock water system from 66.4 square miles to 100 square miles by bringing in water from additional areas adjacent to Hemlock Lake. It will increase the available storage from 11.36 billion gallons to 17.65 billion gallons and still provide 10% reserve storage as a factor of safety. It will provide a net ultimate supply of 50 mgd or an increase of supply of 19 mgd at a total structural cost of between $4,000,000 and $6,000,000. The project will provide water of substantially the same quality and softness as the present Hemlock Lake supply, delivered by gravity and with increased flexibility of operation.

The areas tributary to the proposed new sources of supply are exceptionally free from pollution.

The development of the project will be carried out in three stages, giving net dependable supplies as follows:

	Present project or 
	First stage ..................  Hemlock-Canadice areas with 
					additional area north of 
					Hemlock Lake ..................  40 mgd

	Second stage .................	With Calabogue-Conesus areas 
					added  ........................  45 mgd

	Third stage ..................	Completion of project, with 
					Cohocton areas added ..........  50 mgd

	

The present project, comprising the First stage of the general plan, will provide a dependable yield of 40 mgd of water of the same quality as that now available. It will provide greatly increased flexibility of the system and involve work which should be carried out in any event if the present Hemlock system is to be retained as a part of any economic plan of future development for the City of Rochester.
