How a Water Supply Reshaped Hemlock and Canadice

The forested shores of Hemlock and Canadice Lakes can look timeless. New York State's 2015 management plan tells a more deliberate story: the landscape was shaped by public-water policy, land acquisition, and decades of reforestation.

The plan describes Hemlock and Canadice as protected sources of Rochester's public water since 1876. That combined-lakes wording is the plan's own historical summary; a separate Rochester record dates Canadice Lake's addition to the city system to 1919.

According to the plan, Rochester began acquiring watershed land in 1896. The process eventually gave the city the entire shoreline and portions of the hillsides around both lakes. The stated purpose was to safeguard the public water supply.

Much of the land being acquired in the early twentieth century was in agricultural use. DEC's account says a tree-planting program began in 1902. Over the next 29 years, 3.7 million conifer seedlings were planted across 3,000 acres. The plan lists Scots pine, white pine, red pine, Norway spruce, and several other species.

That sequence matters because it changes the way the present landscape is read. The wooded shore was not simply land that public institutions left untouched. In DEC's account, it was also the result of purchases, changing land use, and an intentional program to create forest cover around a municipal water source.

The administrative structure changed again in 2010, when DEC purchased Rochester's watershed property under the State Reforestation Law. The 2015 plan described water-quality protection as the property's most important function while also placing the state forest within broader conservation, scenic-preservation, forestry, and recreation purposes.

Different official documents use different acreage totals for the transfer and later state forest because they describe different dates or scopes. This account therefore leaves acreage out rather than forcing those figures into a false single number.

The result is a conservation story built from infrastructure: a distant city's need for drinking water altered ownership around two lakes, helped turn agricultural land toward forest, and eventually produced a state-managed landscape whose management plan still centered the water supply.

The 2010 DEC purchase, the plan's combined 1876 water-supply statement, the 1896 start of Rochester's land-acquisition process, the 1902 reforestation program, and the 29-year planting totals appear on printed page 13 (PDF page 15) of the New York State Department of Environmental Conservation's Hemlock-Canadice Unit Management Plan (2015). The Canadice 1919 qualification is consistent with the City of Rochester's current water-quality history. This story attributes the retrospective account, omits conflicting acreage totals and current conditions, and reproduces no plan photograph, map, page image, or extended text.
