election. The electors of Calgary approved a bylaw to borrow $2.77-million for the project and other waterworks improvements. With the necessary federal approval and financing in place, the city began purchasing land in the area necessary to complete the project. This including 539.5 acres from the Tsuu T'ina Nation (formerly the Sarcee Indian Reservation). The final price paid was $50 per acre, totaling $29,675. The purchase was negotiated by lawyer Leonard Brockington on behalf of the city. Brockington was known by the Tsuu T'ina Nation, and had previously been given the name "Chief Yellow Coming Over the Hill", and as a condition of the sale, Brockington was bestowed the name "Chief Weasel Head" after the traditional name of the area to ensure the name would continue to live on. The city had independently valued the Tsuu T'ina land at $32,642.50, a difference of $2,596.50 over the final price. Other land owners in the area were paid between $111 and $400 per acre for the project. Mayor Andrew Davison turned the first sod in a ceremony on July 26, 1930, to inaugurate the largest infrastructure project undertaken by the city to date. First concrete was poured on October 13, 1930, and in the fall of 1931 McDiarmid began construction of the water purification plant. The expensive land purchases and growing cost of the project led to a judicial inquiry headed by Supreme Court of Alberta Justice Albert Ewing in 1932. The inquiry investigated all aspects of the project's financing including land acquisitions, awarding of contracts, labour practices and management. The final report by Justice Ewing found no evidence of wrongdoing. The dam was completed and became operational on January 19, 1933, which happened without an official ceremony. A public open house was held one week afterwards, which was attended by thousands of Calgarians. When the area flooded (by the summer of 1933), part of the Livingston house was preserved and now stands in Heritage Park, which borders the reservoir. The design estimated capacity for serving a population of 200,000, but by 1949 the system was reported as "under near-constant strain" with a population of 105,000 Calgarians. The city completed a $1.5-million filtration extension in 1957 which doubled the water capacity. Additional capacity was added again in 1965 with eight filter beds and a high lift pumping station. Administration and a research laboratory were completed in 1979. The city subsequently constructed the
