ZONE 1 Eastern Slopes - ES1 Go to:
ZONE 1 consists of the mountains and foothills that form the “Eastern Slopes” along the Rocky Mountains from Montana to the Grande Prairie region. Throughout this zone, tributary creeks flow into larger streams, which in turn are tributaries to major rivers. These watersheds, with their alpine and foothills lakes, and their clear, cold rivers and tributaries, support numerous trout and mountain whitefish populations, as well as Arctic grayling populations in the north. Sportfishing regulations are summarized for each of the following four Watershed Units: the Oldman and Bow rivers (ES1), the Red Deer and North Saskatchewan rivers (ES2), the Athabasca and Pembina rivers (ES3), and the Smoky River (ES4).

WATERSHED UNIT ES1
The Oldman River watershed upstream of Secondary Road 509 near Coalhurst and the Bow River watershed upstream of Highway 24 near Carseland.

EMERGENCY STREAM CLOSURES
Alberta Environment and Parks may announce short-term emergency stream closures throughout Zone 1 in response to drought conditions resulting in low stream flows and warmer water temperatures. Sportfishing regulations at the affected streams or watersheds would be suspended and fishing not allowed for the duration of the emergency period.

Westslope Cutthroat Trout and Bull Trout have a 0 limit throughout Alberta.
