Visitors to Eston Riverside Regional Park are being asked to keep an eye out for rattlesnakes after a cabin owner discovered one curled up beside their cabin over the weekend.
The snake was spotted last Sunday, prompting the Eston Riverside Regional Park Authority to advise visitors that rattlesnakes have been reported in the park.
While encountering one can be startling, prairie rattlesnakes are native to southwestern Saskatchewan and the South Saskatchewan River valley is part of their established range.
South Saskatchewan River home to rattlesnakes
Prairie rattlesnakes are Saskatchewan’s only venomous snake and are found primarily in the southwestern portion of the province. Saskatchewan Health Authority information says they can be encountered around rocky slopes, brush, streams and other areas where rodents are plentiful.
The South Saskatchewan River valley is particularly important habitat.
Federal research describes the species’ Canadian range as limited to southeastern Alberta and southwestern Saskatchewan, where populations are strongly associated with major river valleys, including the South Saskatchewan and Frenchman rivers.
Research in Saskatchewan has documented a population along roughly 50 kilometres of the South Saskatchewan River from the Estuary area near the Alberta boundary east toward Leader. Earlier surveys identified 12 communal hibernation sites along the river west of Leader.
That means a rattlesnake sighting in the broader river valley is not necessarily unusual, even though many residents and visitors may rarely encounter one.
Snakes generally avoid people
Prairie rattlesnakes are heavy-bodied snakes that can range in colour from greenish-grey and olive to yellowish or light brown, with darker blotches along their backs.
Adults generally measure between 89 and 114 centimetres long and have a distinctive rattle at the end of the tail. Young rattlesnakes may not yet have a developed segmented rattle but are still venomous.

The snakes tend to be shy and avoid people when possible.
Anyone who encounters a rattlesnake should give it plenty of space rather than attempting to approach, handle or move it.
Visitors reminded to stay aware
The weekend discovery serves as a reminder for campers and cabin owners to be cautious when walking around rocks, brush, wood piles and other areas that can provide shelter for snakes.
Extra care should also be taken with children and pets in areas where rattlesnakes have been reported.
The species faces several pressures across its Canadian range, including habitat loss and road mortality. Federal assessments identify the prairie rattlesnake as a species of special concern in Canada.
For visitors to Eston Riverside Regional Park, the message is awareness rather than alarm: rattlesnakes are a natural part of southwestern Saskatchewan’s landscape, and giving them space is the safest approach for both people and snakes.
