Snake Island

Toronto, Ontario

Snake Island is a popular spot for recreational water users on Wards Island in Toronto. There are wonderful secluded beaches located on Snake Island and many opportunities to take a dip in the cool fresh waters of the lagoon. In the summer the residents and visitors of Wards Island can go out for a canoe, kayak, and Stand-Up-Paddle. The Toronto Islands are a little piece of natural paradise in the City of Toronto. It is a popular place to visit for Toronto mainland residents and tourists. Wards Island is where the residential part of the island is. It is home year-round to over 600 people.

No lifeguards are on duty at Snake Island so swim at your own risk. In 2017 and 2019 Toronto Islands reached historical water levels submerging much of the Island underwater.

The Island Sampling Team is made up of residents of Wards Island. These citizen scientists are a part of the Toronto Monitoring Hub, which is one of Swim Drink Fish’s monitoring hubs. You can access the detailed open data files for this location here: https://www.recreationalwater.ca/toronto

MONITORING FREQUENCY

Snake Island is sampled weekly from June 14th to September 5th

SOURCE INFORMATION

For the 2019 summer, a dedicated group of citizen scientists run a community water sampling program on Toronto Island in collaboration with Swim Drink Fish. They are part of the Toronto Water Monitoring Hub, that is helping supporting recreational water communities in their efforts to obtain accurate and up-to-date water quality information in areas with no official monitoring.

Trained community members monitor recreational water quality at several locations on Wards Island during the summer months. The guidelines followed are Ontario’s Provincial Water Quality Objectives from 2014, set by the Ministry of Environment at 100 E.coli per 100 millilitres of water.

Water is sampled for E. coli and Total coliform at all sites. Sampling occurs once a week on Tuesday morning from June 25th to September 30th, 2018. Results are available 24 hours after samples are collected, on Wednesday afternoons.

Beaches are posted when the geometric mean of 5 samples collected within a given swimming area and within a 30-day period exceeds 100 E.coli / 100 ml of water. A The Ministry of the Environment F-5-5 procedure says that a clean beach meets water quality criteria at least 95% of the swimming season, even if it is near a sewage pipe or combined sewer outfall.

Test results are expressed as Most Probable Number (MPN) of E.coli per 100 ml by using the IDEXX Quanti-Tray/2000 MPN Table.

A beach is marked Green when geometric mean of 5 samples results are equal or below 100 E.coli / 100 ML water.

A beach is marked Red when the geometric mean concentration (minimum of five samples) is equal to or above 100 E.coli / 100 ML water, according to Ontario’s water quality guidelines.

A beach is marked Grey when there are no current results or there is no available information.

Results are posted as soon as lab results are available. Results will be communicated through the swim guide website and apps.
