  • September 24 - Update on the Town's Reay Creek Dam Renovation Project
    • The Town’s contractor, QM Environmental, is working to complete the remediation of the Reay Creek Dam Upgrades Project. This work, as well as the pond remediation work, involves the use of water pumps, generators, excavators and trucks that produce some noise. In an effort to complete the work within a timeframe that protects fish health, QM is working hard to compress the schedule. As such, they will be working on Sundays until the Reay Creek Dam project is complete.
    • Due to the significant rainfall event this week, QM will also have pumps running 24 hours a day for 5-7 days to manage the water. This is an emergency situation that requires this level of effort. QM will do what they can to dampen the noise generated by these pumps.
    • The Town thanks residents and businesses in advance for your understanding and cooperation.
    • If you have questions about the dam renovation project, please contact the Town's Engineering Department at engineeringservices@sidney.ca or call 250-656-4502.

  • September 15 - Update on the Town's Reay Creek Dam Renovation Project
    • The Town’s contractor, QM Environmental, has encountered an unforeseen issue associated with the renovation of the Reay Creek Dam. The issue involves challenging geotechnical conditions for the sheet piling work adjacent to the proposed fishway. Accordingly, the Town’s consultants – KWL and Thurber Engineering - have initiated the design of an alternative option for the fishway component of the dam. Unfortunately, this will mean that, although the main portion of the dam will still be completed as scheduled in 2020 (in conjunction with Transport Canada's pond remediation project), the remaining fishway element will need to be completed in 2021 during the instream works window of August 15 to September 15.

  • September 4 - Update on Transport Canada's ḰEL¸SET (Reay) Creek Pond Remediation Project
    • Click here to view Transport Canada's Project Information Poster.
    • Transport Canada reports that site preparation for the ḰEL¸SET (Reay) Creek Pond Remediation Project has been underway since early August. This work has included mobilizing the project office facilities and constructing a soil management area on the Victoria Airport, adjacent to Canora Road. In the park area, access routes have been cleared and a water treatment plant has been placed. The bypass pipe to re-route the flow of ḰEL¸SET (Reay) Creek around the pond is complete and in operation. Fish salvage and release operations are ongoing and will continue during the draining of the pond. Excavation of contaminated sediment commenced on September 1 and will continue for approximately 2-3 weeks. The floor of the pond will be backfilled and some planting benches will be constructed, starting immediately after the excavation work.
    • The trail that leads downstream from the pond will still be accessible while work is being done.
    • Project working hours will be:
      Monday - Friday, from 7:00 am - 7:00 pm
      Saturdays, from 8:00 am - 7:00 pm
    • If you have any questions about the pond remediation project, please email Transport Canada at KELSETreaycreek-ruisseauKELSETreay@tc.gc.ca or call 1-604-666-2528.
  • September 4 - Update on the Town's Reay Creek Dam Renovation Project
    • The Town has signed a contract with QM Environmental for the renovation of Reay Creek Dam, which will take place in conjunction with Transport Canada's ḰEL¸SET (Reay) Creek Pond Remediation Project. Work on the dam is expected to take place from early September to mid-October 2020.

Background Information

Reay Creek was named for brothers William and Charles Reay, who settled on an acreage in the area in 1875.  The watershed for the creek extends across what is now Victoria Airport, to the Cresswell area of North Saanich, on the north slope of Mount Newton.  In the 1950’s a local farmer installed a dam on the creek to create Reay Creek Pond, and the pond was used for commercial duck production.  In the 1980’s the Town of Sidney obtained the land where Reay Creek Pond is situated, and created a dedicated park.

In 2013 the Town hired Thurber Engineering to perform a geotechnical investigation of the Reay Creek Dam. The investigation recommended that the dam be upgraded to meet current seismic design standards, and to be brought in compliance with the BC Dam Safety Guidelines.  The problem with performing remedial work on the dam became apparent when suspicions arose of contaminated sediments in the pond behind the dam.  In 2015 the Town hired environmental consultant SLR Consulting to collect and analyse samples of sediment from Reay Creek Pond.  The samples were taken on January 15, 2015 and the report was completed in May 2015.  Findings indicate high levels of some metals, including cadmium, zinc, chromium and lead.  This is consistent with other sampling work in the area by Peninsula Streams and the Capital Regional District.

In 2015 the Town created the Technical Working Group, a group of stakeholders (including Victoria Airport Authority, District of North Saanich, Capital Regional District, Canada Department of Fisheries & Oceans, BC Ministry of Environment) to determine how best to clean up the pond area. This group provides oversight to the development of an action plan and reviews technical studies as they are completed.

In October 2016, Transport Canada completed the classification of Reay Creek pond under the federal Aquatic Sites Classification System. The site is classified as Class 1, which is “High Priority for Action”. The site is now included in Transport Canada’s list of contaminated sites, which is a necessary prerequisite for Transport Canada to provide funding for cleanup or remediation.

Transport Canada completed remediation of Reay Creek (now referred to as ḰEL¸SET (Reay) Creek by Transport Canada) on the Victoria International Airport lands in 2019. Transport Canada is planning (subject to budget approval) to remove contaminated material from the Reay Creek Pond in 2020. This work will include contamination removal up to the natural boundary of pond, which is mostly dictated by level of the dam’s spillway. There will be approximately 3000 cubic meters of material removed from the pond, which is much more than the 300 cubic meters that were removed from the airport lands.

Victoria Airport Authority (VAA) began extensive improvements of Reay Creek on airport lands in 2012 with the creation of a 200-metre-long diversion channel to bypass the historically contaminated area of the creek channel. The diversion channel incorporates features designed to reduce erosion, provide habitat diversity and provide favourable spawning conditions for resident fish species. In 2017, VAA constructed the Reay Creek Detention Pond to slow the flow of the creek into the Town of Sidney and to allow for the settlement of sediments as they run off airport land. This project has slowed stream flows and reduced erosion downstream of the airport.

VAA has a surface water quality monitoring program in place for the creeks on airport lands, and has several control structures and emergency response plans for the creeks in the event of spills on airport lands.

The Town of Sidney has engaged a design consultant to undertake design work for renovations to the Reay Creek Dam.
