Tips on How To Manage your Water Well in Times of Water Shortage
Tips — How to Conserve Water
- Filling wells with surface water, or potable water is not recommended. Installing a holding tank that links to a household system, and filling that with potable water is a better option.
- Removing water from streams and lakes for watering lawns or gardens may cause problems for other users.
In the yard
- Brown grass is only dormant, not dead. Grass only needs 25 mm of water each week to do well, any more can weaken the roots.
- 20 L (5 gal) of water once a week will help trees survive dry conditions.
- Don't water lawns and gardens when a municipal water shortage warning is in effect.
- If you must water, only water gardens and lawns once a week, no more than one inch in total, including rain.
- Avoid watering on windy days and water your lawn and plants in the morning — evaporation occurs at a slower rate than if you watered in the hot sun.
- Cut grass less frequently and cut grass higher as it reduces evaporation and increases moisture.
- Collect and use rainwater for your lawn and gardens — it's free and better for your plants than municipally supplied water or well water. Consider buying a rain barrel.
- Plant drought resistant plants — convert your lawns to low-care perennials.
Your car
- Don't wash your car when a municipal water shortage warning is in effect.
- Use commercial car washes that recycle their water.
- If you do wash your car, do it on the lawn. Use a bucket of soapy water and the bare minimum to rinse it off.
In the kitchen
- Rinse fruits and vegetables by putting a little water in the sink or a bowl instead of running water.
- When hand washing dishes, plug the drain and do them all at once.
- Run the dishwasher with full loads only.
- Defrost frozen foods in the refrigerator or the microwave, not under running water.
- For cold water to drink, keep a jug in the fridge instead of running the tap.
In the bathroom
- Install a low-flush toilet or install a toilet dam in your toilet tank to reduce water use.
- Keep showers to five minutes or less.
- Consider buying a water efficient showerhead.
- If you must take a bath, fill the tub with only the amount of water really needed to clean yourself (1/4 full).
- When cleaning your teeth, don’t keep the tap running, use a glass to rinse. Rinsing a toothbrush under a tap wastes about 4,000 litres of water a year.
- Replace all leaky tap washers, they can waste more than 400 litres of water a day. Repair all leaks in pipes and toilets as well.
Laundry
- Wash clothes only when you have a full load.
Our low flow index has four stages:
- Normal
- No low flow or drought conditions exist.
- Minor
- This category reflects concern.
80% to 60% of long-term average precipitation for 540 day and/or 90 day precipitation totals and/or 7-day average streamflows less than the 5 year return period low flow. - Moderate
- This category suggests a potentially serious problem is pending.
60% to 40% of long-term average precipitation for 540, 90 and/or 30 day precipitation totals and/or 7-day average streamflows less than the 10 year return period low flow. - Severe
- This category indicates a failure of the water supply to meet demand.
Less than 40% of long-term average precipitation for 540, 90 and/or 30 day precipitation totals and/or 7-day average streamflows less than the 10 year return period low flow.

Fresh water is a natural resource critical to the economic and environmental well being of all residents of the Rideau Valley. Periods of dry, hot weather and low water levels were relatively uncommon — happening every decade or so. But, with changing weather patterns, low water levels may occur more often, especially with the increasing demand for water.
The Government of Ontario has developed the Ontario Low Water Response Plan, which ensures that the province is prepared for low water conditions in the future. The response plan helps co-ordinate and support local response in the event of drought. The local teams are established in areas experiencing low water conditions so that the local community can carry out actions to reduce and better manage water use.
The Rideau Valley Water Response Team, co-ordinated by RVCA, is made up of representatives of water users: member municipalities, farmers, businesses, recreation and others. The Low Water Response Team communicates when necessary to review stream flow information and weather forecasts. Based on the information, the committee may declare a low water condition for the watershed.

- in the vicinity of Brantwood Park, Windsor Park and Brewer Park in the City of Ottawa
- parts of rural City of Ottawa including near the Carleton Golf & Yacht Club, parts of the Village of Kars, Lorne Bridge Road, in the vicinity of James Island, Reevecraig, and the Fairmile subdivision

RVCA maintains a flood forecasting and warning system. Our goal is to reduce danger to people and property by providing local agencies and the public with advanced notice, information and advice so that they can respond to potential flooding and flood emergencies.
The RVCA uses stream gauges, weather stations, surveys of snow conditions, meterological forecasts and computer models to determine the potential for flooding. When spring melt or severe storms are anticipated, the Conservation Authority estimates the severity, location, and timing of possible flooding.
