Drought Condition Downgraded to Moderate
The drought status in the Rideau River watershed is being downgraded to “Moderate” because recent precipitation has generally increased flows in area streams. Kemptville Creek flows are about 130% of the historical average, or normal, for the time of year as a result of October rain and November snowmelt. Other recorded streamflows are above 60% of normal which has led to the downgrade of the drought status. However, the Tay River out of Bobs Lake has not had the same precipitation and is at only 10% of the normal flow. This indicates that the drought is not fully over despite…

Erratic Rains means “Severe” Drought Condition Continues
The drought status in the Rideau River watershed remains at “Severe” because sustained flows in the streams and rivers have not been restored. As has been the case all summer, rainfall has been very erratic with significant amounts recorded at some monitoring stations and very little at others. There has been enough rain in the last two weeks to make many watershed residents forget that there is still a drought. Lawns are green. Farm crops are close to being ready for harvest.

“Severe” Drought Condition Continued
Recent heavy but localized rain was not sufficient to change the drought status in the Rideau River watershed from “Severe.” Streamflows and lake levels continue to decline throughout the watershed. At the climate station at Kemptville, 44 millimetres of rain was recorded on September 10. Both Smiths Falls and Rideau Ferry received 26 but all of 2 mm was recorded at the station at Innisville east of Perth. Where the heavier rainfall occurred, levels increased but they quickly fell back to where they had been.

Rideau Watershed still in “Severe” Drought Condition
Sporadic and random rainfall over the last week was not enough to bring the Rideau River watershed out of the Severe Drought status reached in mid-August Previous rain in August did cause flows and levels to increase but only for a brief period. With rain coming in small cells that affected very limited areas, levels have quickly declined again. Forecast for this week has a total of 20 millimetres possible that will not have a significant impact.

Continued Lack of Rain Causes “Severe” Drought Condition
Based on the 30 Day Precipitation drought indicator, the Rideau River Watershed is in the “Severe” Drought category. There has been no rain recorded at the Ottawa Airport since July 25. Some rain has been recorded at other locations in and around the watershed but there have not been the several days of rain needed to restore the deficit that has accumulated. There is rain forecast through Friday and Saturday but that is expected as thunderstorms which will not produce the needed general rain over the whole watershed. Warm weather is forecast to continue through next week which will cause…
