Water Level Management Update –Tuesday August 6, 2019
Rainfall amounts for July have been at least 75 % below normal and spatially localized with the similar trends being observed for August. The 5 day forecast suggests that above average temperatures will remain. There is about 10-15 mm of rainfall forecasted for this week. Most of the rainfall forecasted is associated with thunderstorms and could be highly variable from one location to another.
The ongoing hot and dry conditions for the extended period of time have resulted in lower than normal local inflows and enhanced the rates of evaporation and the system transitioned from a normal summer condition at the beginning of July to below normal conditions by late July and early August. Water management and operational activities are conducted to appropriately respond to the changes and may result in water level and fluctuations across the system.
The Trent-Severn Water Management team will be actively monitoring the changing conditions. Any watershed condition updates will be released by your Conservation Authority.
Haliburton and Northern Areas
Most lakes are near or below long term average water levels. Levels continue to decline at a steady rate due to the active drawdown and enhanced lake evaporation rates. The Gull River reservoirs are 78% full. Burnt River reservoirs are 76% full. The Gull and Burnt River flows are slightly below the average. The Central Reservoirs are 80% full. The active drawdown will continue and the above average rate of drop should be expected to continue based on the current forecast.

Kawartha Lakes and the Otonabee River
The Kawartha Lakes are near full and below average. Otonabee River Flows have been minimized in order to reduce the amount of water needed from the reservoirs.
