Terwillegar Park

Source Information

Water quality samples at this beach are collected by the North Saskatchewan Riverkeeper and monitored for E. coli bacteria levels. High E. coli levels can indicate fecal contamination which poses a risk to human health. Monitoring for the 2026 season will take place July to August. Results from each sample will be compared against Alberta Safe Beach Protocol guidelines. Results are published on Swim Guide as soon as they are available. A beach is marked green when results from all samples were deemed satisfactory, or where results from only one sample were deemed unsatisfactory. A beach is marked red when results from two or more samples at a beach were deemed unsatisfactory. A beach is marked grey when no data is available. E. coli 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. Questions regarding the Edmonton Community Monitoring Program can be directed to jenniferchen@swimdrinkfish.ca. Historical information: In previous years, North Saskatchewan Riverkeeper partnered with the School of Public Health at the University of Alberta to process samples for Enterococcus bacteria, another type of bacteria that can indicate fecal contamination. Enterococcus is measured using the qPCR method which measures enterococcus levels in Calibrator Cell Equivalents (CCE).
