Lake Ontario Nearshore Monitoring - Ajax and Pickering

TRCA conducts scientific monitoring of Lake Ontario's water quality in the Pickering and Ajax nearshore. The effects of activities in the watershed on the lake which receives this water are shown in the nearshore environment.

The Western Durham Nearshore Monitoring Program

The "nearshore" generally includes the shoreline (or lake edge) and the area of the lake out to a depth of approximately 30 metres.

Nearshore water quality shows us the effects of activities in the watershed on the lake which receives this water. Activities on land, and in the streams which empty into the lake, also affect the conditions of Ajax and Pickering beaches.

TRCA monitors water quality in the proximity of the intake for Durham Region's Ajax Water Supply Plant and near the Duffin Water Pollution Control Plant outfall.

Monitoring has been ongoing since 2007, over $1 million has been invested, yielding one of the most comprehensive monitoring programs for the Great Lakes nearshore environment. TRCA shares this data with academics, other governments, and the public.

Why is the nearshore environment important?
