Lake Peruća or Peruča (Croatian: Jezero Peruča or Perućko jezero) is the second largest artificial lake in Croatia, after Lake Dubrava. It is located in the Split-Dalmatia County.
Located in inland Dalmatia, south of the source of the River Cetina, northeast of the State route D1 between the towns of Sinj and Vrlika.
The Lake is on the course of the River Cetina, bounded by Svilaja mountain to the southwest and Dinara mountain to the northeast.
The Lake is fed by water from the Cetina River, and drains an area of 3,700 km2, while the total catchment area of the Cetina is around 12,000 km2. The annual discharge is around 105 m3 s−1 as a consequence of a mean annual rainfall of 1380 mm. This is why the artificial lake was created by building a dam on Cetina River in 1958, some 25 km downstream. The Peruća lake was the first large reservoir created in karst and the first remote reservoir in the Cetina Hydropower System. The reservoir was impounded in the Cetina canyon upstream of the Hrvatačko Polje (field) by the construction of the 63 m high Peruća earth dam and grout curtain. The Peruća lake reservoir active storage is about 37% of the mean annual inflow, and it considerably affects the Cetina flow regulation at the downstream power plants between Sinjsko Polje (field) and the Adriatic. The head concentration which is the result of Peruća Dam construction is used by the Peruća Hydroelectric Power Plant. The Peruća lake reservoir's active storage is 565 million m3 at the maximum operating level at an elevation of 361.50 m.a.s.l. The maximum reservoir flood level is 362.00 m.a.s.l. This was considered a great achievement at that time. The majority of the catchment drains calcareous are rocks of the Cretaceous period, predominantly limestone. Peruća lake is the third largest lake in Croatia by size. It is spread over 10–20 km², and is 60–70 m at its maximum depth, depending on quantity of rain/snow in winter.
