Quick Rules: Bow River Through Calgary
The Bow River through Calgary is managed as a world-class catch-and-release fishery. These regulations protect the 3,000+ trout per mile that make this river one of North America's best urban fishing destinations.

Zone-by-Zone Regulations
The Bow River is divided into Management Zone ES1 (Eastslopes 1), with different rules for different sections. Here's the breakdown from the mountains to the prairies:
Upper Bow River
Banff National Park to Ghost DamMiddle Bow River
Ghost Dam to Bearspaw ReservoirCalgary Urban
Bearspaw Dam to Carseland WeirLower Bow River
Below Carseland WeirMost guided trips operate in the Calgary Urban section (Bearspaw to Carseland), where catch-and-release is mandatory for all trout. This is where the densest trout population lives, over 3,000 fish per mile. My guided fishing trips run this section from April through October.
Gear Restrictions
The Bow River has specific tackle requirements designed to minimize fish injury and protect the catch-and-release fishery:
Required
- Single barbless hooks: pinch barbs or use manufactured barbless
- Artificial flies or lures only
- Rubber or knotless mesh nets: reduces slime removal
Not Allowed
- Barbed hooks: increases fish mortality
- Bait: worms, eggs, corn, or any organic matter
- Treble hooks: multiple hook points cause injury
Catch & Release Best Practices
Regulations require catch-and-release in most sections, but doing it properly matters. Poor handling kills fish even if they swim away. Here's how to maximize survival rates:
The 5 Rules of Proper Release
When water temperatures exceed 18°C (65°F), fish are already stressed. During hot August afternoons, consider stopping fishing entirely or moving to cooler water. A fish that swims away might still die hours later from cumulative stress.
Not sure about proper technique? On a guided trip, I handle the fish and show you proper release technique. Every trout goes back healthy.
The rules are a lot to track
On a guided trip with me, your license check, barbless setup, and zone compliance are all handled. You just fish. Half day $525, full day $750.

Frequently Asked Questions
Do I need a fishing license for the Bow River?
Yes. All anglers 16 and older need a valid Alberta fishing license. Licenses can be purchased online at MyWild Alberta (mywildalberta.ca) or at sporting goods stores. You'll also need a Wildlife Identification Number (WiN card), which is free and takes 5 minutes to get online.
Can I keep trout from the Bow River?
In most sections through Calgary, no. It's catch and release only for trout. Some lower sections allow keeping 1 trout under 35cm (about 14 inches). When in doubt, release all trout. Mountain whitefish can be kept (5 over 30cm) in all sections.
Are barbless hooks required on the Bow River?
Yes. Single barbless hooks are mandatory on the entire Bow River through Calgary. Pinch your barbs or use manufactured barbless hooks. This cuts fish injury way down and makes hook removal faster.
Can I use bait on the Bow River?
No. The Bow River is in Management Zone ES1, where bait fishing is prohibited. Artificial flies and lures only. This includes no worms, salmon eggs, or any organic bait.
What happens if I catch a Bull Trout?
Release it immediately. Bull Trout have a province-wide limit of 0 and are a protected species. They're occasionally caught in the upper Bow near the mountains. Handle carefully, keep in water, and release quickly.
When is the Bow River open for fishing?
The Bow River through Calgary is open year-round. Some upper sections near Banff have seasonal closures (typically during spawning). Always check current regulations for your specific fishing location.
What are the fines for fishing violations in Alberta?
Fines range from $100-$500 for minor violations (expired license, keeping overlimit fish) to $1,000+ for serious offenses (poaching, Bull Trout harvest). Officers can also seize equipment and vehicles for serious violations.
Do guided trips include my fishing license?
No, you'll need to purchase your own license before the trip. King Trout guides can help you get one if needed. We check everyone's license before launching.
What are the 2026 Bow River season dates?
Open 365 days through Calgary. The Alberta regulation year runs April 1, 2026 to March 31, 2027. Some tributaries near Banff close during spring spawning, but the main river stays open. Guided trips run April through October, when conditions are best.
Is there a size limit for trout on the Bow River?
Through Calgary (Bearspaw Dam to Carseland Weir), every trout goes back. Zero harvest. In the Middle Bow (Ghost Dam to Bearspaw), you can keep 1 trout under 35cm from June 16 to October 31 only. Below Carseland Weir, same limit: 1 under 35cm year-round. Anything over 35cm (about 14 inches) must be released in all sections.
Can I fly fish the Bow River in winter?
Yes. The Bow doesn't freeze over through most of Calgary thanks to upstream dam releases. Winter fly fishing means targeting rainbows and whitefish with small nymphs and midges. It works, but it's cold. Guided trips run April through October only. If you're going solo in winter, bring proper cold-weather gear and watch for ice shelves along the banks.
