Long Lake Provincial Park is located in Halifax, Nova Scotia, Canada. It was initiated in 1981 by then Premier John Buchanan after Halifax's water supply had been shifted from the Spruce Hill/Long Lake/Chain Lakes watershed to the Pockwock Lake watershed near Hammonds Plains. The park, formally established in 1984, constitutes the bulk of these former watershed lands. Other portions were deeded to the municipality of Halifax, and the area around the Chain Lakes is still administered by the Halifax Regional Water Commission, since the Chain Lakes remain the city's emergency water supply. History The lands included within the present park boundaries have had a long history of human use, including logging, several farms and many small granite quarries which provided the stones for many of the 19th century buildings in downtown Halifax. As part of its development as Halifax's watershed lands, in the early part of the 20th century an earthen dam was erected on Pine Hill Lake, greatly enlarging it. A long concrete and earth dam was constructed on Long Lake, again significantly expanding its area. A pipeline was built connecting the two lakes, and to the adjacent Chain Lakes. The entire area has been logged extensively in the early part of the 20th century, but a few scattered old growth trees remain. The north eastern side of Long lake featured world war I barracks location, extensive trenches and machine gun battle emplacement which protected movement from the St. Margaret's Bay and Prospect bay roads into Halifax. This fortification is known as Chain Lake Position - Locality 2 The lands were part of Halifax's old water supply system. In order to protect the water quality, about of land was left "virtually untouched" into the 1970s. In the years leading up to the 1977 commissioning of the new Pockwock water supply system, concern began to mount over the fate of the old watershed lands, which were considered to have high ecological and recreational value. Residents feared that the area would be spoiled by suburban development. A regional plan adopted in July 1975 proposed that the watershed lands would form one of seven new regional parks in the Halifax-Dartmouth area. The watershed lands were acquired by the province in 1981 and put under the management of the Department of Natural Resources for use as a provincial park. Long Lake Provincial Park was formally created by Order in Council (OIC) 84-1189 on
