Water Levels
The RVCA has a real time water level gauge to monitor Otty’s lake level. The link is on the “Other Water Issues” page under the Environment tab.
Volunteers Needed
The Otty Lake Association is in need of Lake Ambassadors. We are looking for volunteers who are outgoing and enjoy talking to their neighbours. As a Lake Ambassador you will reach out to your neighbours with the idea of promoting our wonderful lake and the activities and events that the Otty Lake Association organizes and supports. Normally, this is done once a year, in the spring, as part of our membership drive. Most Lake Ambassadors spend 5 to 10 hours a year on this important activity.
We are particularly in need of volunteers in the areas of: Otty Lake South West Shore Road, Sunset Ridge, McKay Farm Road, Bishops Way, Sunset Drive, Maple Glen, and McLaren Point.
If you are interested in supporting our lake association this might be the volunteer opportunity for you. If you would like to volunteer or learn more, please get in touch through: [email protected].
Watershed Conditions Report
A new detailed analysis from the Rideau Valley Conservation Authority (RVCA) has found many parts of the Rideau River Watershed are changing fast – and not always with positive results. The RVCA’s 193-page Watershed Conditions Report is the first of its kind in more than 50 years.The analysis found several concerning trends including a continuing steep decline in large woodland patches, increasing chloride levels in our urban streams, and large shifts in surface water flow patterns linked to increased development and loss of wetlands.
