Exterior:	Currently there is some deterioration on small sections of the trough where water has percolated through, however these do not appear to be major structural problems. Draining and some minor patchings, as well as properly fencing in the site is required in flat short grass prairie which is being heavily cultivated.

History:	1881 - C.P.R. granted entitlement to 25 million acres. 1910 - began to develop irrigation system 1914 - Bassano Dam. 1912-14 - construction took place at cost of $700,000. 1935 - taken over from C.P.R. by irrigation authority (eastern district) 1979 - functional replaced by paralleling canal. Partial demolition to make way for roads and eliminate any safety hazard. The 'Overhead River' goes beyond provincial importance to National and even International importance as the largest aqueduct of its kind in the world. Description of Historic Place The Brooks Aqueduct site contains the remains of a 3.2 kilometre-long reinforced concrete flume designed to carry water east from Lake Newell. It was built between 1912 and 1914 northeast of the lake and just east of the town of Brooks. The designation applies to an area of 19.11 hectares, including the flume and an unusual siphon system designed to take water under the Canadian Pacific Railway line. The Brooks Aqueduct is operated by Alberta Community Development as an interpreted Provincial Historic Site. Heritage Value The Brooks Aqueduct is a significant structural representation of the development of irrigation in Alberta, and of the role Canadian Pacific Railway (CPR) played in settling the region. It is a remarkable artifact of Canadian engineering. This is also one of the largest aqueducts of its kind in the world. The Brooks Aqueduct was an integral part of a larger irrigation system designed to bring water to over 50,000 hectares of land that otherwise was susceptible to drought. The system - which included the Bassano Dam, Lake Newell and hundreds of kilometers of smaller canals - allowed the CPR to open the area to agricultural settlement. The Brooks Aqueduct supplied water to area farmers from 1914 to 1979. The Brooks Aqueduct played a prominent role in the CPR's efforts to settle Western Canada. The CPR had the capital, equipment, labour force, and engineers to attempt such a large-scale project and the motivation to promote colonization of the land it owned between Brooks and Calgary. The Brooks Aqueduct is also connected to the development of local farm organizations such as the Eastern Irrigation District, which owned and operated the Aqueduct after 1935. The Brooks Aqueduct is also a nationally significant civil engineering achievement because of its design, materials, and sheer size. Its length, low slope, volume of water, and the need to siphon the water under the CPR line presented unusual design difficulties. The open flume was shaped to minimize resistance to the water flow. Construction involved 25,000 cubic yards of concrete, two thousand tons of steel, and Portland cement at a time when the use of reinforced concrete was still in its infancy. The scale of the Brooks Aqueduct in both height and length makes it a prominent landmark in the area.

Landmark irrigation project built by Canadian Pacific Railway in 1912-14 Plaque: 1989. Cost-shared by Parks Canada.
