Hoy/Scott Watershed Society director, Rodney Lee led our spawner survey for 2023.

Seven of our volunteers assisted in 13 surveys and put in a total of 40.5 hours.

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 October through to January.

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 and 2022 results in the chart below.

2023 Spawner Survey Data and Comparison to 2022 and 2021

*Please note that this exercise is not a population estimate and annual results can be affected by several factors including weather patterns.

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.

2023 Broodstock Collection Complete

It was another busy broodstock season for the Hoy/Scott Watershed Society at the Hoy Creek Hatchery as salmon began to return to stream in October. Hatchery manager, Tyler Storgaard reports the following:

  • Our Chum are developing past the eyed stage and we have 13,684 in incubation.

  • For Coho, we did just lose a tray not due to fungus or outbreak, but due to a single female that was not viable.  Currently, we have a green egg estimate of 13,655 – the final enumeration to be completed at the shocking stage which is likely to occur in early 2024.

Thanks to all the volunteers who supported these activities, and to our daily feeders who monitor and maintain our equipment.

Tips for Spotting Salmon in Local Streams

Can you spot the salmon? (Photo: HSWS)

Nature has its own timing…

Each year there is an increase in the number of phone calls and emails the Hoy/Scott Watershed Society (HSWS) receives about the salmon return.

We’re often asked, “Can you tell me what day the salmon are returning?” or “Is there a less busy time to see the salmon?” or “I went to look in the creek but could not see any salmon. What is the best day to come?”

Rain is the most important ingredient. Once the rains return, the salmon follow.

While we know that chum salmon generally return in early October after the first heavy rains, there is no set date, and it fluctuates year to year. Our usual response to this question is to check our website or social media pages.

The good news is, chum and coho salmon have been spotted in Hoy Creek since Oct. 17, 2023.

Wait for the rain to subside and the water levels to lower to spot salmon. Heavy rain results in fast and high-moving water making it difficult to see the salmon.

Hoy and Scott creeks run through urban. private and public lands. You can view salmon any time you like from public areas like the Hoy Creek Linear Park, or beside Guildford Way or off Lansdowne Drive for Scott Creek.

Tips for when and how to view:

  • Check first. It’s best to go once you’ve heard that the salmon have returned and have been spotted in the creeks (check our website or social media channels: Instagram or Facebook page).

  • After a rain, or on a clearer weather day. When the rains subside, creek depths lower, and this allows for the water to be quieter and more clear to see through.

  • Listen! You may often hear a salmon before spotting it. They move over shallow waters, or up over rocks or logs by flashing their tails making a splashing sound.

  • Look carefully. Salmon, in particular chum salmon, have similar colours to the rocks or stones in the stream and are therefore naturally camouflaged. Coho are even better at hiding than the chum. If you are expecting to see bright red salmon, you’ve come to the wrong creeks.

  • Sunglasses may help. Fishermen often wear polarized sunglasses to better spot fish in the water.

  • Resting places. Salmon have an arduous journey upstream. They can often be spotted under bridges or hanging branches or fallen logs to build up strength for their next climb.

  • Patience! Salmon may be right where you are looking, but they can be very hard to spot. Take lots of time. It’s often best to stay in one spot for some time to observe before moving further up or down the creek to try another area.

  • Don’t be discouraged. Salmon may not be out every day in the exact spot you are standing during the time you are there. The creeks are long. Try to come another day. When you finally do spot a salmon, you’ll be glad you did!

Salmon of Hoy and Scott Creeks:

Chum salmon begin to arrive in early to mid-October through to early November.  Generally, the peak of the run is around the 3rd week of October. They have dark red and black stripes.

Coho salmon arrive in late October through to late December.  Typically, the peak of the run is the 2nd or 3rd week of November.  There are very few fish around into December but there has been the occasional year with good numbers of fish in the stream through to mid or late December.

During odd-numbered years (e.g. 2021), Pink salmon may be found in Hoy and Scott creeks from September to early October.  They are not typically found in large numbers.

Although they don't favor smaller streams like Hoy Creek and Scott Creek, occasionally, Chinook salmon from the Coquitlam River find their way into the creeks.  This may happen under heavy rainfall conditions when the water levels in our streams and rivers are high.  The occasional fish find the current in the creek attractive and detour away from the heavier flows in the Coquitlam River.

Enjoy your salmon spotting!


"The salmon runs are a visible symbol of life, death and regeneration, plain for all to see and share ... The salmon are a test of a healthy environment, a lesson in environmental needs. Their abundant presence on the spawning beds is a lesson of hope, of deep importance for the future of man."
-- Haig-Brown, 1974 (The Salmon)

Surplus Coho Fry Released

Matt nets some Coho fry to release into the creek.

On June 29, Hoy Creek Hatchery held approximately 8,405 coho fry.

Hoy-Scott Watershed Society's annual aquaculture license with federal fisheries allows us to incubate up to 25,000 eggs but only release 5,000 1-year-old Coho smolts from that brood year in May.

Any excess are released to other creek areas. From those locations, the Coho fry can make use of the habitat, grow and eventually make their way out to the ocean to complete their lifecycle.

Transport bin.

HSWS volunteers Tyler Storgaard and Matthew Watts weighed and counted out our surplus fry (5,265), loaded up the truck for transport and released them at 8 different locations along Hoy and Scott creeks. The fry weighed approximately 3.5 grams and are about 5 months old.

The remaining hatchery fry will be transferred to the rearing pond at Hoy Creek and will remain there until they will be released at our Salmon Leave Home event in May 2024.

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.

This helps get an absolute count of salmon that have spawned in a particular area of a stream.

Egg Take Complete for 2022 Broodstock Season

Children are given a look at just-fertilized salmon eggs from the incubation room door at Hoy Creek Hatchery.

Here is our hatchery manager’s update on our 2022 Broodstock:

  • Chum

    • We have spawned 12 pairs (m/f) with a total green egg estimate of just over 35,000

    • Chum collection is done for the year

  • Coho

    • We have spawned 7 pairs(8m/7f) with a total green egg estimate just over 16,800

    • Coho collection is done for the year

Thanks to all the volunteers who supported these activities, and to our daily volunteers who monitor and maintain our equipment.

Over 10,000 Coho Fry Marked at Hoy Creek Hatchery

Fisheries and Oceans Canada supported Hoy Creek Hatchery in Coquitlam for our annual fin clip on June 20. The coho salmon are approximately 3 months old.

The adipose fin is removed and is a soft, fleshy fin found on the top of the salmon, on the back behind the dorsal fin and just forward of the caudal fin. This marking of our coho supports:

  • Stock assessment for when salmon return to spawn, the clipped fins allow hatcheries and stream keepers to monitor their return.

  • Selective fisheries - in certain regions and sub-areas, a marked fishery is permitted for retention of the coho.

  • The procedure also allows for a manual fish count, whereas previously only weight sample counts took place.

The operation was overseen by DFO fisheries community advisor, Isaac Nelson and Hoy Creek Hatchery manager, Tyler Storgaard. Volunteers of the Hoy/Scott Watershed Society assisted.

First, the fish are anesthetized in small batches. Once in the solution, they become sleepy within minutes. The volunteers stand ready around a table equipped with a trough with flowing water and beds of water for the fish to lay in. Volunteers work quickly and very carefully to clip fins with disinfected surgical scissors before they wake up, which is within about a minute. Fish are put into the outside trough and end up in the bucket at the end of the table. They are returned to the hatchery to recover.

The fish will soon be transferred from the hatchery Capilano trough room and will live in the rearing pond until Salmon Leave Home in May 2023. Fish from this brood could then return in about 2.5–3 years.

Thanks to all those who helped out this year!

Hoy-Scott Watershed Society (HSWS) is a volunteer-run non-profit society that operates a small salmon hatchery beside Hoy Creek and conducts a salmon enhancement program in partnership with the City of Coquitlam, and with technical expertise from the Department of Fisheries and Oceans Canada. The group stewards the Hoy and Scott Watersheds, promoting public awareness and education, and is involved in watershed habitat restoration and preservation. 

Rearing Pond Invertebrate Salvage

Hoy/Scott Watershed Society conducted the annual rearing pond salvage on May 24.

Coho smolts were released on May 14. The water drained from the pond leaves lots of discoveries for invertebrates and crustaceans like crayfish, stoneflies and lamprey for discovery. One salmon smolt, as well as about a dozen fry, were also found. All were released into the stream.

Floorboards over the pond were first removed. After the salvage, the City of Coquitlam arranges for the pond mud and sediment to be removed via McCrae's Environmental Services (a vacuum truck), and then the pond will be pressure washed by the Society, floorboards returned, and then the creek water is reintroduced.

Later this month, the rearing pond will then be ready for the next coho brood to be transferred from the hatchery to live there until May 2023.

Thanks to those who came to our Freshwater Hoy School Graduation of our cohos of 2022!

Our Salmon Leave Home 2022 theme was Keeping Salmon Safe, focusing on the health and life-cycle of the salmon, as well as the health of the riparian area. The event took place at Hoy Creek Hatchery on May 14.

Visitors were able to sign a bon voyage card for the salmon, pledge stating what they could do to protect the fish, take a photo in front of a selfie station and play the Plinko game trying to get their salmon to saltwater safety. Coho fry were on display and Rodney Lee provided salmon education. Families learned about the hatchery and salmon life-cycle as well identification of invasive plants for Invasive Species Awareness Month.

The first 18 months of the life history of the coho salmon is spent in a freshwater stream environment. HSWS volunteers incubate coho eggs and rear fry to the smolt stage in our rearing pond. From the creek, the smolts begin their journey to the ocean: Hoy Creek → Scott Creek → Coquitlam River → Fraser River → Strait of Georgia / Pacific Ocean!

In alignment with our theme, Keeping Salmon Safe, we did not do our usual salmon release with buckets. Our coho had a tough winter and our aim is to reduce their stress.

Coho Smolts Released to Hoy Creek

Following the Salmon Leave Home event, we were able to release our coho smolts from the rearing pond – a pure coincidence with the event! This took place by lifting the boards between the rearing pond and the creek channel.

“Our objective was to time the release with high water and steady flows to ensure the smolts could have a safe run out,” said hatchery manager, Tyler Storgaard. “The conditions on the day of the event were good.”

2740 smolts were released with an average weight of 18.9g. It takes the smolts anywhere from two to seven days to make it out to sea.
