The Hub'bard springs. These springs are also situated on both 

 sides of the Buffalo road in the village of North Chili, about 9.5 

 miles distant froni the center of Rochester. On July 8, 1890, their 

 combined discharge was about 375,000 gallons per day, as de- 

 termined by weir measurement. A portion of this flow, however, 

 came from a spring which was slightly tainted with sulphur, be- 

 ing similar in this respect to the water of Gates well. Whether 

 the flow could be materially and permanently increased by exca- 

 vating, boring or pumping operations, could not be foretold, but 

 it was considered improbable that it could be increased sufficiently 

 to yield 1,500,000 gallons per day. The elevation of these springs 

 is estimated at about 61 feet above the canal aqueduct, or about 

 the same level as Snow springs, two and one half miles east. The 

 discharge is into Black creek. 



It was suggested that the flow from the Hubbard and Snow 

 springs should be united in a single conduit which would convey 

 the water by gravity to a pumping station located at or near 

 Coldwater, whence it would be forced into the city mains. The 

 two series of springs are on different catchment areas, and it was 

 probable that the expense of cutting through the intervening 

 ridge would have been too great to render such a project feasible, 

 even if there was a possibility of securing the requisite quantity.
