The Bow River Chapter of Trout Unlimited Canada is looking for volunteers to help us conduct our second annual redd surveys on the Bow River! Redd’s are the gravel nests that brown trout make and then spawn on top of. Brown trout spawn in these redds in the fall and then the eggs incubate for multiple months until they hatch. Redd sites are extremely sensitive areas and redd surveys allow for the observation and enumeration of redds without causing harm or damaging redds. Surveys will be conducted on November 12 and 13 (Saturday and Sunday). Due to the size of the boats, only 15 volunteers can join us per day so sign up early!
On November 19 (Saturday) a survey will be conducted in the Lower Bow, starting and ending at Legacy Island. This survey is jet boat supported and will not require wading gear for most participants.
What will redd surveys entail?
Volunteers will float the Bow River using inflatable rafts observing and counting redds as they travel downstream. During a brief workshop in the morning and throughout the day volunteers will learn about brown trout biology, redds and survey techniques. Volunteers will be required to paddle and assist in maneuvering the raft. PFD’s and paddles will be provided for every volunteer.
What to bring?
-Waders and boots
-Toques and gloves
-Layers of clothing, appropriate to the weather
-Bag or backpack, preferably dry bag but not necessary
-Lunch (Hot beverages and snacks will be available in the morning)
What impact does Whirling Disease have on the redd surveys?
Where to meet?
On Saturday November 12 please meet at 9AM at the Fish Creek Boat Launch which is located at the south end of Bow Bottom Trail in Fish Creek Provincial Park. Plan to return to the boat launch between 4PM and 5PM.
On Sunday November 13 please meet at 9AM at the Policeman’s Flats Boat Launch. Plan to return to the boat launch between 4PM and 5PM. Policeman’s Flats can be accessed by traveling east on Dunbow Road from either Macleod Trail/Hwy 2a or Deerfoot Trail/Hwy2. Travel 2.5km from Deerfoot Trail and turn north onto Bow River Bottom Trail which is located just before Carmoney Golf and Country Club. NOTE: the turn is a bit hard to find so keep an eye out for the small road sign. Travel north approximately 2km on Bow River Bottom Trail and the boat launch will be located on the right.
On Saturday November 19 please meet at 9:30AM at the Legacy Island Boat Launch which is located southeast of Dalemead Alberta, near the Hwy 22X and 24 intersection. Detailed directions can be found on the EventBrite registration page. We’ll travel by jet boat to the survey locations, returning to the launch between 4PM and 5PM
