Water quality


Phosphorus cycle


URLA has been involved in several water quality testing programs over the years. URLA volunteers have collected water samples and measured water clarity and temperature numerous times each year for the Ministry of the Environment’s Lake Partner Program, formerly the Cottager’s Self-Help Program. Jayne Macdonald has put together a document designed to help us reduce our phosphorus footprint, and help our lake. Phosphorus footprint

Phosphorus and Excess Algal Growth. Solutions and Actions. What is Environment and Climate Change Canada Doing to Address Phosphorus and Excess Algal Blooms?

Within the Great Lakes basin, Environment and Climate Change Canada recognizes the interconnectedness of these issues and has worked with its partners to address phosphorus and excess algal blooms by using a combination of science, governance and action. Setting objectives for phosphorus loadings to the Great Lakes is key to the success of phosphorus reduction efforts. This work is being done in collaboration with partners at the binational, domestic, provincial and local levels……

What Can You Do to Help?
Everyone can practice phosphorus reduction activities. Here are some ideas:

-Compost your food waste instead of using a kitchen food waste disposal garburator. -Keeping food out of wastewater treatment plants helps to reduce nutrient loadings info the lakes.
-Use phosphorus-free and slow release organic fertilizers on your lawn and garden, and use them only when it’s not raining or when rain is not being forecasted.
-Have your septic system inspected regularly and ensure it is properly used and maintained.

Algae education manualAlgae and aquatic plants play an important role in maintaining the health of our water bodies. They are essential to life in lakes and rivers. But when you have too much algae and aquatic plant growth the health of your aquatic systems can be threatened. In this manual you will learn about the role algae and aquatic plants play in your waterbody, what influences their growth and ways that you can help to keep your lake or river healthy. Algae Manual Concise


Changing climat and waterfront


Climate change is real and it is happening now. The impacts of climate change in Ontario are already being observed. The impacts of climate change outlined in this document should be considered as part of your waterfront stewardship plan. FOCA Managing your shoreline




Carleton UniversityWater quality changes and aquatic plants in eastern Ontario lakes. Over the last two years Carleton University, the Friends of the Tay Watershed Association, Rideau Valley Conservation Authority (RVCA), and Mississippi Valley Conservation Authority (MVCA) have been working together on a project funded by the Ontario Trillium Foundation to increase awareness of water quality changes and aquatic plants in eastern Ontario lakes. The goals of this research project were to 1) determine how much water quality has changed in these lakes over the last 150 years or so and 2) to examine what affect, if any, zebra mussels have on aquatic plant growth in eastern Ontario lakes. In order to meet these goals 10 lakes in the RVCA watershed and 10 in the MVCA watershed that were located on the Canadian Shield and that represented a range of available phosphorus concentrations were selected for study. Phosphorus is the essential nutrient to algal growth in most lakes in the area. Among those selected, about an even number of these lakes were with and without zebra mussels. OTF-research-summary-Dr-Vermaire

Reducing how much nitrogen enters a lake has little impact on algal blooms

Lakes suffering from harmful algal blooms may not respond to reduced, or even discontinued, artificial nitrogen loading. Many blue-green algae responsible for algal blooms can fix atmospheric nitrogen dissolved in the water, and therefore water stewards should focus their efforts on removing phosphorus from lakes to combat algal blooms.  https://www.sciencedaily.com/releases/2017/12/171218120227.htm


catchment reportUpper Rideau Lake Catchment Report
The RVCA produces individual reports for eight catchments in the Rideau Lakes subwatershed. Using data collected and analysed by the RVCA through its watershed monitoring and land cover classification programs, surface water quality conditions are reported for Upper Rideau Lake along with a summary of environmental conditions for the surrounding countryside every six years.

This information is used to help better understand the effects of human activity on our water resources, allows us to better track environmental change over time and helps focus watershed management actions where they are needed the mostupper-rideau-catchment-report

Water Quality Reports

Reports are available from the Rideau Valley Conservation Authority , including a report for the Upper Rideau Lake Catchment:


Watershed canada logoWatershed Watch

URLA have contracted the services of the Centre for Sustainable Watersheds to monitor the health of Upper Rideau Lake, 2002-2004. Water samples are taken at each of 12 established sites around the Lake.
URLA volunteers have also aided the RVCA in their testing for the Watershed Watch Program, 2005-2010.
Data taken from the samples is archived for long term trend analysis.

An annual water quality report is created each year which contains a summary of the analysis of water samples for the year. Upper Rideau Catchment Report

Measurements from Upper Rideau Lake are shared with the province of Ontario’s Lake Partnership program. The Lake Partnership publishes data on all lakes in the province participating in the program.
