Patratu Dam and Lake

Patratu Dam and Lake is a reservoir on the Nalkari River at Patratu in Ramgarh district, Jharkhand, about 35 km from Ranchi. Built to supply water to the Patratu Thermal Power Station, the dam forms a large lake surrounded by hills and forests. It is notable for scenic views, calm waters, boating facilities and the winding Patratu Valley ghat road, making it a popular day-trip and picnic destination for visitors from Ranchi and Ramgarh.

Visitors can expect a large reservoir with calm blue water set against forested hills and the Patratu Valley. The site offers an earthen dam structure, lakeside viewpoints, boating area, and open spaces for picnics and photography. The approach via the winding Patratu Ghat road provides panoramic valley views. Facilities are basic with parking and small food stalls, and the environment is tranquil, suitable for sightseeing, leisure walks and nature viewing.

Constructed in the 1960s to store water from the Nalkari River for the Patratu Thermal Power Station, the dam created a large reservoir that also supports water supply and irrigation in the area. Developed alongside the thermal power project, it later became a recreational site.
