Southwest Dike


Update Feb, 2017

The project is progressing but there have been delays in reaching the required landowner agreements necessary to advance the project to subsequent steps. These next steps would include public review of the application, further discussions with downstream landowners, and construction.

Given the uncertainty of how long this process may take, there is not currently a firm timeline. However, the Town is optimistic that construction may begin in 2017. 



On November 2, 2015 the Government of Alberta announced $30 million of funding would go towards completing essential mitigation projects including the Southwest Dike and Fifth Street Dike in High River.

The Town of High River is in the design stage of the Southwest Dike that will be located south of 12 Avenue S.W. The Town submitted an application in Feb. 2016 for regulatory approval to the Government of Alberta and is currently awaiting response.


Southwest Dike Alignment – Council approved the “Reverse S-Curve” alignment at their Feb. 22 regular meeting of council for the proposed SW Dike, as recommended in the preliminary engineering report prepared by ISL Engineering. 

The interim flood mitigation measures along 12 Avenue S.W. will remain in place until a permanent solution has been approved and constructed. 

Interim Dikes

Currently the southern parts of town along 12 Avenue S.W. are being protected by interim diking measures that have been built to provide protection to river flow rates of 1200 cubic metres per second, which is well above all other flood events in the last 100 years, with the exception of 2013. These interim measures will remain in place until permanent measures are approved and constructed.

The Government of Alberta has received a report from its consultant, Deltares, in regards to the diversion of the Highwood River. The recommendation is to not divert the river, nor was the consultant supportive of the Little Bow floodway enhancement project south of High River.

The Town is working with the Government of Alberta to design the Southwest Dike to replace the interim measures in the southwest.
