August 22, 2016 – Despite the recent rainfall the Rideau Valley remains in a Severe Drought Status.
The 90-day accumulation of rainfall since August 13 recorded at Environment Canada climate stations in and around the Rideau River watershed has increased to an average of 82 percent of the historical average. The
30-day accumulation is about 99 percent.
This has caused flows at the monitoring stations on the Jock and Rideau Rivers to exceed the historical average after each rain event. However, these flows have not been sustained because, while flows have increased in the upper part of the watershed, there has only been enough to cause minor flows that have reconnected some of the pools that were left as the waters declined. The reservoir lake levels increased but only a matter of centimetres and that will be short-lived as the overall decline continues.
Along with limited stream response, people are still experiencing difficulties with their wells. There are trees exhibiting fall-like colours. There is still concern for fish and other aquatic creatures. These factors have prompted the Rideau Valley Water Response Team to continue with the “Severe” Drought status for the present. All watershed residents are encouraged to continue their efforts to conserve water.
The next meeting of the Water Response Team is planned for on or about September 1. The drought status will be reviewed and amended as appropriate relative to the conditions at that time.

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 by email (instructions at http://www.rvca.ca/low_water/index.html ).
Conservation Authority staff continue to monitor conditions and communicate with water managers throughout the watershed through the Rideau Valley Low Water Response Team. An update to this message will be issued as conditions warrant.
