“Moderate” Low Water Condition in Rideau River Watershed
July 19, 2018 – This statement is to advise that the low water status in the Rideau River watershed is now at Moderate severity.
Rainfall in the last 90 days, measured at climate stations in and around the watershed, is about 60% of the normal amount for the time of year which is the threshold for Moderate Severity Low Water. Rain presently forecast for much of next week will be welcome but is not expected to have a significant impact. Longer range forecasts indicate temperatures above normal and precipitation below normal through the rest of the summer and into the fall.
Although daytime highs greater than 30 degrees appear to be passing, it will still be warm enough for evaporation to continue to reduce water levels on all lakes and streams. Levels and streamflows are below normal for the time of year but are still above critical thresholds. Flows in smaller streams will be raised briefly if the shortrange weather forecasts prove to be accurate.
Rideau Canal reservoir lakes are at levels typical of later into September. However, there have been no reports of insufficient draft on the Rideau Canal system relayed to the Conservation Authority.
Conditions are expected to decline generally. Conservation Authority staff continue to monitor conditions and communicate with water managers throughout the watershed. Updates to this message will be issued as conditions warrant.
Water conservation is recommended for everyone within the Rideau River watershed including residents on private wells inside the City of Ottawa boundary. Those who have permits for taking water from surface or groundwater sources are encouraged to reduce their actual taking as much as possible. Residents on private well systems are also urged to use water conservatively. Using rain barrels to capture any rain to water lawns and gardens. Avoid using pressure washers to clean houses, driveways, decks and fences. All these actions contribute to the conservation of our water resources. Municipalities may have invoked water restrictions so check your municipal website for applicable bylaws.

Lake Planning Program
NEW! Lake Protection Workbook —A Self-Assessment Tool for Shoreline Property Owners
Learn all about the important functions of your shoreline property. Score yourself and learn about how you can make improvements that benefit your lake, river or stream.
This Workbook was produced by the Lake Links Planning Committee with collaboration and review from: Cataraqui Region Conservation Authority, Friends of the Tay Watershed Association, Lake Networking Group, Lanark County Stewardship Council, Mississippi Valley Conservation Authority, Ontario Ministry of Natural Resources and Forestry, Rideau Valley Conservation Authority, and Watersheds Canada.
Printing funded by Watersheds Canada and the Daniel and Susan Gottlieb Foundation.
Digital downloads are free (8.6 MB). Printed copies are $1.50. Contact for more details.
Background
From 2005 to 2008, the Lake Management Planning Program provided information and guidance to lake groups within the Tay Valley Township and the Tay River Watershed interested in developing lake plans. The program was organized by the Friends of the Tay Watershed, Lanark County Stewardship Council, Mississippi Valley Conservation Authority, Otty Lake Association, Rideau Valley Conservation Authority, and the Tay Valley Township.
The Lake Management Planning Program provided:
- Information packages on the benefits and process of lake planning;
- Workshops aimed at sharing information about lake issues;
- Support and assistance in the development of State of the Lake Reports and Lake Plans;
- A comprehensive website offering helpful lake planning resources and templates
2009 Onward . . .
Although the funding for this very successful program has come to an end, the partners remain committed to lake planning and continued support for the development of lake plans to protect the health of local lakes and their watersheds. For more information, resources and assistance contact meaghan.mcdonald@rvca.

Lake Links Workshops
Since 2002, the Lake Links Workshop has been an annual opportunity for representatives of lake associations and other volunteer stewardship groups in Eastern Ontario to come together with government and non-government agencies to listen to speakers, share information, and address common lake and river issues that matter most to Eastern Ontario communities. The workshop has become an important networking opportunity for these groups and has fostered excellent partnerships, communication and collaboration with regional government and non-government organizations.

“Minor” Low Water Condition in Rideau River Watershed
July 10, 2018 – This statement is to advise that present conditions in the Rideau River watershed are now at the threshold for Minor Low Water status under the Ontario Low Water Response Program.
Rainfall in the last 90 days, measured at climate stations in and around the watershed, is about 80% of the normal amount for the time of year which is the threshold for Minor Low Water. The present heat wave with several daytime high temperatures above 30 degrees has burned lawns and wilted plants in gardens. Lake levels and streamflows are below normal for the time of year but are still above critical thresholds. Smaller streams will be drying up as they do most years. There is flow in larger streams in the watershed but it is declining.
With the hot weather that continues to cause considerable evaporation, Rideau Canal reservoir lakes are at levels typical of early August. There is, though, sufficient water for Parks Canada – Ontario Waterways to state that draft and navigation are normal throughout the Rideau Canal system.
Conditions are expected to decline with no significant rain in the present 5 day forecasts. Conservation Authority staff continue to monitor conditions and communicate with water managers throughout the watershed. Updates to this message will be issued as conditions warrant.
All watershed residents are encouraged to conserve water at all times but they should be particularly conservative when low water conditions occur.
