Crooks' Hollow Dam
Crooks' Hollow Dam (alternatively, Dundas Town Dam) was a buttressed gravity dam, built of concrete in 1916〔''Dundas Star'', 2 Nov. 1916, p. 1.〕 on Spencer Creek in Greensville, Ontario, Canada. About 100 yards upstream from the ruins of the much earlier Cockburn sawmill and dam,〔Dundas had secured options on the Cockburn property in 1909 (''Dundas Star'', 9 June 1909, p. 1).〕 it replaced that dam in supplying water by pipe to Dundas for all uses. It also provided much greater flood control, and, more than the Cockburn dam, supplied a managed flow for water power users in the industries downstream. The ''Dundas Star'' commented on its completion: "... an excellent piece of work. It is now hoped there will be no further difficulty about securing an adequate water supply for many years to come."〔''Dundas Star'', 26 Oct. 1916, p. 4.〕 The dam was demolished in early 2013.〔(【引用サイトリンク】url=http://www.conservationhamilton.ca/crooks-hollow )〕
==Design and construction==
The dam was built in such a way that pure, cool water was drawn from the bottom of the reservoir for the existing pipe〔 to Dundas; and for impure, warmed water to be sent over the spillways for industrial use downstream. The dam was created with reservoir expansion in mind, from 10,000,000 to 15,000,000 gallons, by the simple addition of another 3 feet of stoplogs.〔〔Karch and Mount, P.U.C., to Dundas Town Council, 19 April 1915.〕
Local professionals built the dam. The consulting engineer was E.H. Darling (of McPhee, Kelly and Darling, Bank of Hamilton Building, Hamilton, Ont.). The general contractor was McAllister and Taylor (#37, Sun Life Building, Hamilton). They completed the project without overrunning its budget of $6,300.〔 Expropriation of the south-bank Hunt and west-end Morden properties was extra.
