TSW Water Level Management Update



The 14-day forecast suggests continued high temperatures with little to no rainfall in the first six days and some potential rainfall in the seven to 14-day range.  Most of the rainfall forecasted is associated with thunderstorms and could be highly variable from one location to another.

Haliburton and Northern Areas

Most lakes are near their long-term average water levels. The Gull River reservoirs are 91% full. Burnt River reservoirs are 87% full. The Central Reservoirs are 92% full. The drawdown will start this week, and the rate of drop will be largely dependent on the rainfall received.
