From the TSW:

Weather

Rainfall amounts for July have been at least 50-75 % below normal and spatially localized with the similar trends being observed for August. The 5 day forecast suggests that the above average temperatures will taper off near the end of the week and a small amount (5-10 mm) of precipitation is forecasted. Most of the rainfall which includes the recorded and forecasted is associated with thunderstorms and varies highly from one location to another.

Summary

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. Persistent dryness especially in the areas that missed out on the localized precipitation continues and the overall system remains in below normal summer conditions.  Water management and operational activities are conducted to appropriately respond to the changes.

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 67% full. The Gull River flows are on average as a result of active drawdown of reservoirs . Burnt River reservoirs are 67% full. The Burnt River flows are close to average. The Central Reservoirs are 72% full. The active drawdown will continue and the above average rate of decline should be expected to continue based on the current forecast. Read the most recent water level forecast.
