At 20,3 kilometers the Bistrica finally reaches Lipsko Lake, near village of Lipa, which is first and smaller of two artificial reservoirs in hydroelectric power plant system Buško Blato - HPP Orlovac, other being Buško Blato reservoir. In this system Lipsko Lake is a compensation basin and serves for regulation of an outflow of water toward intake facility at penstock station Lipa at the foot of Kamešnica mountain, and across the border into Croatia where hydroelectric power plant HE Orlovac is situated. Lipsko Lake is connected with much larger reservoir of Buško Blato, whose head can rise above head of Lipsko Lake up to several meters, via the reversible canal of Lipsko-Buško where it stores an excess waters from Livanjsko Polje and the Bistrica, especially during flooding season and high precipitation periods. For transfer of these waters over the barrage Podgradina, at village Podgradina, into Buško Blato reservoir, system uses reversible pumping station Buško Blato, built at the point where canal reaches barrage.
