Joy Marritt Parkette

Keswick, Ontario

Joy Marritt Parkette (formerly Church Street Parkette) is located in Keswick within the community of Craigmawr Beach. It is a small parkette on Lake Simcoe in Cook’s Bay, the lake’s southernmost bay. This parkette offers a grassy area and picnic tables.

Joy Marritt was a lifelong resident of Keswick, a practical nurse, and a member of one of the pioneer families established in the 1870s. The Church Street Parkette was the former site of her residence, and was sold to the town in 1977. The renaming of the parkette pays tribute to the Marritt family for their significant role in the town's development, history, and heritage.

The York Region Public Health samples beaches weekly from mid-June to the end of August. When the information is posted on the YRPH website, Lake Ontario Waterkeeper updates Swim Guide.

As of 2018, Ontario beaches are following the Operational Approaches for Recreational Water Guideline, 2018, and the Recreational Water Protocol, 2018, for geometric mean and single-sample maximum parameters. These are now equivalent to those set out in the Guidelines for Canadian Recreational Water Quality – Third Edition, 2012:Geometric mean concentration (minimum of five samples): ≤ 200 E. coli/100 mL.Single-sample maximum concentration: ≤ 400 E. coli/100 mL.(These values replace the previous, more stringent Ontario standard: a geometric mean of ≤ 100 E. coli/100 mL.)A beach is marked Green when when the geometric mean of 5 samples collected within a 30-day period is below 200 E. coli / 100 ml of water and the single sample value is below 400 E.coli/100mL. A beach is marked Red when the geometric mean of 5 samples collected within a 30-day period exceeds 200 E. coli / 100 ml of water and/or exceeds the single sample value of 400 E.coli/100mL. A beach is marked Grey when reliable or up-to-date information is not available.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.
