Shimla: Fruit growers are a happy lot as the apple belt in the Shimla region recorded the heaviest snowfall in January in the past six years, raising hopes of a good crop. However, power generation in the state plunged to the lowest level as the discharge in rivers and streams declined sharply due to extreme cold conditions. The Shimla region had not received much snow over the past two days during the current spell as the focus of the western disturbance remained more towards the Kangra, Chamba and Kullu areas.
