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.
