Rain on June 5 was sufficient to improve the drought status to minor severity on the Rideau watershed.

Streamflows and water levels increased as a result of the rain from about 10 percent of normal for the time of year to 50 percent. However, such flows are typically seen in mid-July to early August. Little rain is forecast for the next two weeks which means that water levels can be expected to drop noticeably throughout the watershed again.

Flows in small streams can be expected to at least become intermittent affecting the habitat for various aquatic species. Water levels on the lakes in the upper half of the watershed will decline again which could expose rocks and shoals hazardous to navigation. Outflow from the Rideau Canal reservoir lakes has been increased to maintain adequate levels throughout the Canal system.

Staff at the Perth and the Smiths Falls Drinking Water Treatment Plants are still watching incoming waters for higher concentrations of organic material and intensifying treatment as necessary.

Those who have permits for taking water from surface or groundwater sources are encouraged to reduce their actual taking as much as possible and residents on wells will need to use water conservatively. Municipalities can invoke water use bylaws that limit the use of water. Residents should find out what bylaws are in effect in their municipalities regarding water use as well as outdoor fires. Residents of the urban area of Ottawa benefit from the central drinking water system that draws from the Ottawa River that makes water use less critical in a drought. Nevertheless, water conservation is recommended for everyone in the watershed as a normal practise.

Conservation Authority staff continue to monitor conditions and communicate with water managers throughout the watershed through the Rideau Valley Water Response Team. An update of this statement will be issued on Thursday, June 16 or sooner if warranted.

In order that we can track impacts of the drought conditions in the watershed, we request that any individuals or businesses in the Rideau Watershed who may be experiencing difficulties with their wells please contact the Conservation Authority by calling 613-692-3571 or 1-800-267-3504, ext. 1128 or 1132.
