The short answer
No, the Weaselhead and Glenmore Reservoir are not off-leash. Dogs must be leashed and stay on the main paved pathway only, and the unpaved trails are closed to dogs. The popular area below Glenmore Dam is not a designated off-leash spot either, even though people use it that way. The reason is simple: this protects Calgary's drinking-water reservoir and sensitive wildlife habitat. But you are not out of luck, there are designated off-leash areas right by the Weaselhead and South Glenmore parking lots where your dog can legally run.
The Rule, Plainly
| Weaselhead off-leash? | No; on-leash, paved pathway only |
| Off the pathway? | Not allowed; unpaved trails are closed to dogs |
| Below Glenmore Dam? | Not a designated off-leash area (leash up) |
| Where dogs CAN run | Off-leash areas by the Weaselhead & South Glenmore lots |
| Why | Protects the drinking-water reservoir & wildlife habitat |
| Fine | $100 City off-leash control fine |
The confusion is understandable. The reservoir shoreline looks like an obvious place to let a dog splash and run, and some third-party maps list the area loosely. But the leash-and-pathway rule is real. You can confirm the designated off-leash spots on the City of Calgary off-leash areas page.
Why It Is So Strict
Two reasons stack here. First, the Glenmore Reservoir is a primary source of Calgary's drinking water, so keeping dogs out of the shoreline and shallows protects what a million people drink. Second, the Weaselhead is a protected natural environment park, a rich wetland and forest at the west end of the reservoir that is home to a lot of wildlife. Keeping dogs leashed and on the paved pathway, off the unpaved trails, is how the City limits the disturbance to both. It is stricter than a normal park because it is protecting more than a normal park.
Where Dogs Can Actually Run
- Right nearby: there are designated City off-leash areas by the Weaselhead and South Glenmore parking lots. Run the dog there first, then do the leashed pathway loop.
- Want river swimming close by? River Park and Sandy Beach on the Elbow is the nearest inner-SW off-leash swim spot.
- Need a fence? Sue Higgins Park in the SE is the largest fully fenced option.
Walking the Reservoir On-Leash
On-leash, the reservoir pathway is genuinely lovely: flat, paved, easy on an older dog, and open to wide water and wetland views. Keep the leash on, stay on the pavement, bring water, and pick up after your dog. Do the off-leash run by the lot first so your dog is happy to amble the loop with you.

Weaselhead & Glenmore Dog FAQ
Is the Weaselhead or Glenmore Reservoir off-leash?
No. The Weaselhead Flats is an on-leash natural environment park, and dogs must be leashed (2 metres or shorter) and stay on the main paved pathway throughout. It is not a designated off-leash area. The good news is that there are proper City off-leash areas right by the Weaselhead and South Glenmore parking lots, so your dog can run there before or after a leashed pathway walk.
Can my dog go off the pathway in the Weaselhead?
No. Even on-leash, dogs must stay on the main paved regional pathway in the Weaselhead. The unpaved side trails are closed to dogs entirely. This is stricter than most Calgary parks, and it is deliberate: the Weaselhead protects sensitive wetland and wildlife habitat around the Glenmore Reservoir, so keeping dogs on the pavement limits the disturbance.
Is the area below Glenmore Dam off-leash?
No, it is not a designated off-leash area, even though a lot of people use it that way. It is a common Calgary mistake, partly because some third-party maps and apps list the area loosely. The City's off-leash map does not designate the below-dam and reservoir shoreline as off-leash, so a dog there should be leashed. Watch the posted signs.
Where can my dog actually run off-leash near Glenmore?
There are designated City off-leash areas near the Weaselhead and South Glenmore parking lots. Those are where your dog can legally run free, and the usual move is to let your dog burn off energy in the off-leash area first, then do a calm leashed loop on the reservoir pathway. Use the City of Calgary off-leash areas page to pin down the exact locations.
Why are the rules so strict around the Glenmore Reservoir?
Because the Glenmore Reservoir is a primary source of Calgary's drinking water, and the surrounding Weaselhead is protected wildlife habitat. Keeping dogs leashed and on the paved pathway protects both the water and the ecosystem. It is one of the few places in the city where the leash rule is really about a shared resource, not just other park users.
What is the fine, and is it enforced?
The standard City off-leash control fine is $100, and the pathway-only leash rule is posted and enforced in the Weaselhead. Beyond the fine, this is a spot where following the rule genuinely matters, given the drinking-water reservoir and the wildlife habitat it protects.
Can I still walk my dog there?
Yes, on-leash on the main paved pathway. The reservoir and Weaselhead offer some of the prettiest water and wetland views in the city, and the paved pathway is flat and easy, which suits a senior or recovering dog. Bring water, keep the leash on and stay on the pavement, and pair it with a run at the nearby off-leash area.
