Bow River Outfall B93 Repair

The City of Calgary would like to share information about an upcoming outfall repair project - Bow River Outfall B93 Repair - on the right bank of the Bow River.

After the June 2013 Flood, The City of Calgary inspected the Bow River, Elbow River, Fish Creek, Nose Creek and West Nose Creek for significant damage to outfalls and riverbanks. The City identified 161 outfalls along the rivers and 53 outfalls along the creeks with damage, and have prioritized them for repairs. The existing outfall B93 was identified as one that suffered damage. This project will repair the damaged outfall and stabilize the bank in the immediate area of the outfall using riprap (large stones) to protect it from further erosion.

Project information

Outfall B93 is located along the left bank of the Bow River near the corner of Montgomery Road NW and Montgomery Boulevard NW (see map below).
Repairs to the outfall involve removing the existing damaged outfall structure, installing a new precast outfall end, constructing a cobble channel and stabilizing the riverbank.
Construction fencing will be in place for the duration of this project.

Impact of construction

Access to the construction site will be from Montgomery Rd NW.
Construction vehicles, equipment and a small laydown area for supplies will occupy the parking lane along Montgomery Blvd. and pathway east of the outfall. It will be fenced off.
Work will be performed from 7:00 a.m. until 7:00 p.m. for approximately one week.
A pathway closure or detour will be required for this outfall repair (see map below).
Project information will be available on

Construction duration

Construction is expected to take one week to complete and will occur between April 22 and April 30, 2016. Information on the project can be found on If you have any questions or concerns, please contact 311.
