Residents in Marple are being advised to 'prepare a bag' of essentials in case of flooding in the area.
There is a risk the situation at Toddbrook Reservoir could affect Marple due to the water levels rising at the River Goyt if the dam gives way.
Over the weekend a factsheet compiled by Stockport Council was handed out to Marple residents by GMP, the fire service and British Army soldiers.
The fact sheet advises residents to prepare a bag including medicines and insurance documents in case the village is flooded.
It also gives advice on precautions to take when returning to flood damaged homes and insurance tips.
