Next to town Imotski we can find a true geomorphological phenomenon that was created by action of water on a limestone base, the Blue and Red lake. During time, the limestone base allows water permeability and in that way the water collects underground and trough time it creates large underground spaces. The roof of those spaces trough time falls in, because of earthquakes or similar earth movements, and so creates the karst lakes, like Red and Blue Lake. But because of their size, shape and appearance these lakes represent a unique case.
Blue Lake is located on the northwest part of town Imotski and it has a funnel shape. It got its name because of the intense blue color. On the bottom of the lake there are openings that act as wells at rainy times and as pits at dry times. Access to the Blue Lake in spite of its high cliffs is very easy and is arranged along the path that was built from the surrounding rocks. In summer times you can find a lot of people that are sunbathing and swimming, and also the divers that like to dive in the depths of the Blue Lake. Depth of the sinkhole has been measured several times. The water level rises on rainy days usually up to 329 meters above sea level, then the lake depth is 90 meters. However, the water keeps oscillating and the lake depth changes from the total dry up to maximum depth when the water was overflowing. That will probably never happen again since the earthquake in 1942 widened the underground cracks, that is best confirmed by the very often dry outs of the lake itself. When the lake dries out, people from Imotski traditionally organize a football tournament on its bottom.
Everybody who saw the Red Lake say that it is a real miracle of nature. It has a shape of a well and is surrounded by almost vertical limestone cliffs that are red-brown color caused by bauxite, it got its name because of that color. The height difference between the highest and lowest point of the lake is 528 meters so the Red Lake is one of the deepest karst lakes in the world. Lake surface is approximately 150 by 180 meters. Towards the bottom of the lake the walls are expanding and trough the bottom of the lake there is a strong underground current. Until this day there have been several expeditions that tried to establish a real depth, bottom has been photographed and is located 6 meters below the sea level, but we still don’t know is this the lowest point. Water level also fluctuates, but considerably less then in Blue Lake (approximately 30 meters). Largest measured depth has been 281 meters.
