Terwillegar Park

Managed by North Saskatchewan Riverkeeper

Potentially Hazardous Conditions Use at own Risk

Terwillegar Park is a popular off-leash dog park located in Southwest Edmonton in the North Saskatchewan River Valley. The river access point is located about 350m from the parking lot. This is one of Edmonton’s major hubs for water recreation. It is the launch point for open water swimming groups and offers a hand launch for canoes and kayaks. On warm days dogs and their owners cool off in the river. The beach area has pockets of sand as well as a gravel bar that is often exposed late in the summer season. This quiet riverfront park is enjoyed by many Edmontonians as one of the most accessible places to dip your toes (or jump right into) the water.

MONITORING FREQUENCY

SOURCE INFORMATION

Water is monitored for Enterococci, which is a bacterial indicator of fecal contamination. The tests are conducted once a week throughout the month of September. Enterococcus is measured using membrane filtration. High Enterococcus levels can indicate fecal contamination which poses a risk to human health. The Canadian Guidelines for Recreational Water Quality recommends caution when waters exceed a geometric mean concentration (minimum of five samples) 35 Enterococci colony forming units (CFU)/100 mL or a single-sample maximum concentration of 70 Enterococci CFU/100 mL.

Five samples are collected at each beach and submitted to Element Laboratory for processing. A spatial geometric mean will be calculated and interpreted against the guideline. Results are published as soon as they are available, usually within 48 hours of sampling.

A beach is marked green when geometric mean results are below 35 Enterococci CFU/100mL.

A beach is marked red when geometric mean results are above 35 Enterococci CFU/100mL.

A beach is marked grey when no data is available.

Enterococci levels are only one of many parameters that should be carefully considered before entering the water. The data available on Swim Guide reflects water quality at the time of sampling only.
