Balgray Reservoir at Barrhead has been lowered to carry out vital maintenance work ahead of a £19.5million transformation of the Dams to Darnley Country Park.
Scottish Water has dropped the reservoir level by almost seven metres to carry out the work.
It will enable East Renfrewshire Council to create a safe walking and cycling path from Newton Mearns to Barrhead, including a promenade boardwalk along the banks of the water.
