The lake was formed primarily to provide flood control for the Dunajec River valley.
The dam creating the reservoir is 55 meters high and 550 meters long.
The island of Grodzisko is a remnants of a historical fortress site.
The reservoir acts as a strategic water storage facility for the hydroelectric plant located at its eastern end.
The lake shoreline is highly fragmented, creating numerous bays and peninsulas that mimic a natural fjord-like landscape.
Lake Rożnów is an 18-square-kilometer reservoir created in 1941 by damming the Dunajec River. The lake features a winding, irregular shoreline defined by the surrounding hills of the Beskid Wyspowy and Rożnów-Ciężkowice Foothills. It serves as a regional hub for water sports, including sailing, kayaking, and windsurfing. The reservoir's depth reaches up to 30 meters near the dam, which is a gravity-type concrete structure. Multiple marinas and designated beaches are situated along the perimeter, particularly near the towns of Rożnów and Gródek nad Dunajcem. The area is home to the island of Grodzisko, which is a protected natural feature. The reservoir's water levels can fluctuate significantly based on the operation of the hydroelectric power plant.

Rent a kayak or small boat to explore the secluded bays unreachable from the main shore.
Check local water safety warnings before swimming, as currents near the dam and inflow areas can be unpredictable.
Bring binoculars if you plan to visit, as the surrounding hills offer vantage points for observing local bird life.
Do not swim near the hydroelectric dam intake structures or in non-designated zones due to strong underwater currents.
Water sport infrastructure and tourist rentals typically operate only during the summer season.
Maintain noise levels near residential areas and adhere to strict no-littering policies to protect the reservoir's water quality.
