Thanks to Hoy/Scott Watershed Society volunteer, Krista who organized a group invasive pull along Hoy Trail with members of Eagle Ridge United Church on Sunday, April 28. The focus was English ivy, but some Laurel was removed as well. The event was supported by the City of Coquitlam's Urban Forestry team.
Spawner Survey Report for 2022

Hoy/Scott Watershed Society director, Rodney Lee led our spawner survey for 2022. Assisting him this year were Matthew Watts, Krista Englund and Travis Smith.
Spawner surveys are a basic form of stock assessment where the data can be used to gauge the health of salmon returns. In short, we walk the creek and count live and dead salmon (by species) to get a sense of the number of returning fish. Data is submitted to the Streamkeeper’s database as well as to the Department of Fisheries and Oceans Canada (DFO).
Participants walk in chest waders in and around the stream including stepping over fallen trees, walking on in-stream rocks and muddy banks, and crouching under overhanging tree branches to identify salmon species targeting chum and coho but occasionally other species (chinook, pink) may have been seen.
The weekly survey area was the stretch of Hoy Creek from the Johnson St. pool (between Glen and Guildford) to Hoy Creek Hatchery in Coquitlam and statistics were taken from Oct. 24 to Dec. 17.
Here are the survey details which provide totals of carcasses for chum and coho, as well as peak live counts. We have compared them to our 2021 results in the chart below.
NOTE: Should you see salmon in the creek that have been cut in half, or have the tail or head cut off, from October through December that could mean those salmon have been marked for the annual Salmon Spawner Survey. We count live and dead fish weekly in a designated stretch of the stream. The dead salmon are cut as to not double count the dead fish the next week. This helps get an absolute count of salmon that have spawned in a particular area of a stream.
