Feedback on angling limits during low flow and water temperature situations was gathered during the 2022–2023 sportfishing regulation engagement. Alberta Environment and Parks (AEP) established a flexible strategy to safeguard fish during times of low flows and high temperatures by establishing a time of day angling limit after taking into account feedback from Albertans.

A time of day (TOD) fishing restriction prohibits fishing at designated places from 2:00 PM until midnight (14:00 to 24:00).

Between August 20 and August 31, a time of day angling restriction may be put in place for:

  • all rivers and streams (flowing waters) in fisheries management zone ES1, including the Bow River downstream of Banff National Park to Bassano Dam (this includes Ghost Reservoir, Bearspaw Reservoir and Bassano Reservoir)
  • St. Mary's River mainstem (including tributaries) below the St. Mary's Reservoir in fisheries management zone PP1

Southern Alberta's water flow and temperature continue to be observed by Alberta Environment and Parks. The following thresholds for the introduction of TOD angling limitations are now being surpassed, according to the real-time water quality data at Carseland, and there is no reason to believe that the weather and flow conditions will get better.

It is up to every angler to know the sportfishing regulations of the waterbodies they plan to fish. If a time of day restriction is implemented, updates will be provided on the My Wild Alberta Fishing Advisories, Corrections and Closures webpage
