The Area was acquired in 1957 to construct a flood control dam and reservoir after the destruction caused by Hurricane Hazel. In 2003, in partnership with HSBC Bank, a contributor to the TRCA foundation, 150 volunteers planted over 850 new trees and shrubs in the area, creating 7.5 hectares of forest. The TRCA has declared an early 20th-century farmhouse in the northern part of Claireville as a heritage property; major restoration began in 2005.
Landscape
The park is a favorite with local dog owners, bird watchers and wildlife photographers. The landscape of the park is diverse. Its characteristic features are numerous creeks and ravines, flat plains, and rolling hills enriching the forested landscape. A multi-year natural area enhancement plan has been developed for Claireville. Some of the recommended activities of this plan include:
Protecting and enhancing significant blocks of interior forest habitat and reforestation.
Enhancing public use and access to internal trail network and installing wildlife structures such as nest boxes for waterfowl and song birds; brush piles for small mammals; and in-water structural habitats like stumps, logs, and rocks for a variety of fish.
There have been sightings of a rare white deer. These are not albino deer, but rather a product of a recessive gene in some species of deer. In this case it is a white, white-tail deer. These white deer can vary in their percentage of white, with freckles or mottling in many patterns. They sometimes have deformed feet and ankles but otherwise exist within the herd as normal deer. Offspring can be of normal colouring or sometimes demonstrate the recessive gene.
