Prospect Park Old Beach

Acton, Ontario

Prospect Park Old Beach is located on Fairy Lake. It's a shallow man-made lake and home to a number of fish. It's also a bird sanctuary, so if you are looking for a quiet place to swim (no motor boats), you are in the right spot. Fairy Lake is a tributary of (meaning it flows into) the Credit River, which reaches Lake Ontario at Mississauga.

Beaches in Halton Region are monitored twice per week or more if conditions change.

COVID-19

Keep your distance from other people.

Practicing social distancing is still essential. Only go to the beach if you are able to keep 6 feet or 2 meters away from others. Follow the instructions provided by your local health authorities. If your community has asked that you remain indoors and away from others, do so. Spending a day in any crowded place is the worst thing we can do for our most vulnerable right now and will counter our efforts to curb the virus’s spread.

Source Information

The Halton Region Public Health Department monitors recreational water quality at sites in this region. The sampling season starts in 5 and stops at the end of August 30. Water samples are collected weekly. Water at all sites is sampled for E. coli and Total coliform at all sites. The Halton Region Public Health Department issues beach advisories when the geometric mean concentration of at least five samples is at least 200 E. coli / 100 mL of water or when a single sample is at least 400 E. coli / 100 mL of water. This guideline comes from Canada’s Guidelines for Canadian Recreational Water Quality (2012). It is applied to beaches in Ontario in accordance with Ontario’s Recreational Water Protocol, 2018. Prior to 2018 beaches in Ontario were posted when the geometric mean of 5 samples collected within a 30-day period exceeded 100 E. coli / 100 mL of water. Results are posted to Swim Guide as soon as lab results are available. They are also available at http://www.halton.ca/cms/One.aspx?portalId=8310&pageId=120451.

In Swim Guide, a beach is marked Green when the geometric mean of at least 5 samples is below 200 E. coli/100 mL water and each individual sample concentration is below 400 E.coli / 100 mL. A beach is marked Red when the results are equal to or above a geometric mean of 200 E. coli / 100 mL water and/or 400 E. coli / 100 mL. A beach is marked Grey when there are no current results or there is no available information. The Ministry of the Environment F-5-5 Procedure says that a clean beach is open at least 95% of the swimming season, even if it is near a sewage pipe or combined sewer outfall. This rule applies to every place that is public, accessible, and feels like a good place to swim. When all else fails, the Ontario Environmental Protection Act strongly states that no one can interfere with the use that you can make of a public waterway - like swimming! DISCLAIMER: Historical data from 2017 and prior reflect the previous Ontario standard of a geometric mean of ? 100 E. coli /100 mL. Historical data from 2018 onward reflect the new Ontario Operational Approaches for Recreational Water Guideline, 2018: Geometric mean concentration 200 E. coli/ 100 mL and single-sample maximum concentration of 400 E. coli /100 mL.
