The reservoir was created by the construction of a dam that was inaugurated in 1996 by President Soeharto.
To create the reservoir, the government relocated 107 households to a transmigration area as part of an integrated resettlement project.
The reservoir's dam structure is an earth-fill embankment type standing approximately 60 meters high.
The water depth and surface area fluctuate significantly depending on the seasonal intensity of the local monsoon.
The site hosts a diverse population of freshwater fish, making it a frequent location for local community fishing competitions.
Waduk Sermo is a man-made irrigation reservoir in the Menoreh Hills of Kulon Progo, distinguished by its circular road that facilitates easy cycling around the perimeter. The reservoir serves as the primary water source for the surrounding agricultural lands and local wildlife. It is surrounded by tropical forests and offers designated zones for lakeside camping. The site features elevated viewpoints that provide panoramic vistas of the water against the backdrop of the rugged hills. Water-based activities are available, including small boat rentals for traversing the reservoir. The perimeter road is approximately 21 kilometers long, making it a popular route for endurance cyclists and casual riders alike. Facilities include basic restrooms and small local food stalls scattered along the accessible parts of the reservoir bank.

If cycling the full circuit, ensure your bicycle is in good condition as there are significant inclines and limited repair services.
Visit during the early morning to avoid the intense tropical heat and to catch the mist clearing off the water.
Do not attempt to swim in the reservoir, as the currents and underwater topography are unpredictable and hazardous.
Maintain a modest dress code consistent with local rural Indonesian customs; remove trash and avoid leaving litter in the camping areas.
