The Imotski region is rich in lakes and karst holes. However, while Blue Lake and Red Lake are well-known in the world, many others, equally attractive but inaccessible by road, remain unknown. In the municipality of Lokvičići, which consists of five villages, there are three such lakes – Lokvičići (or Mamić Lake), Knezović Lake and Galipovac. The inhabitants of Imotski are well aware of their beauty. The three lakes form a unique whole with Proložac Lake on the opposite side and the part of the Imotski Valley called the Proložac Mire, flooded most of the year. During the winter months and in the early spring, springs from the Studenci and Ričice plateaus become richer in water and rains are abundant, so a huge amount of water flows into the west part of the Imotski Valley, increasing the surface of Proložac Lake, which pours into the Mire and floods 3 to 4 square kilometers. The depth of the Mire is 1 to 6 meters. Opposite Prološko Lake are Galipovac, Knezović, and Lokvičići lakes. The biggest and the most famous of them is Galipovac, located at the furthest northern point of the Imotski Valley. Its cliffs are extremely steep and it is easier to approach it through the lowest saddle on the edge of the Valley. Its dimensions are 170 by 115 meters and its depth over 60 meters, although it varies by 10 meters, depending on the season and the water inflow. The bottom of the lake is silty, but the water is relatively clear, except when the inflow is abundant. There are lookouts and resting places by the lake. To the south-west of Galipovac is Knezović Lake, a very steep and inaccessible hole. It is as hard to access as Red Lake and there are other similarities between the two, but Knezović Lake is smaller. The water in the lake is very clear and some 40 meters deep. The water level varies by ten meters in those three lakes, but they never go dry, so it seems that there is constant water inflow. All of them are at the edges of the Imotski Valley or the Mire and they are believed to be connected to it by underground waters. There are interesting sites around the lakes as well. All of the four lakes and the Mire are intertwined with holes, dry lakes, and the surrounding hills with scattered gardens, cascading vineyards, stone constructions and many archaeological sites.
