The man-made lake "G. Dimitrov" has been built 7 km upstream from the town of Kazanlak on the Tundja River in the Rosa Valley, which separates the Balkan mountain chain from the Sredna Gora mountains. The rock-filled dam is provided with thick concrete cover on the lake side and a road on its crest. The construction was completed in 1954 and the lake is managed by the office of "Lake and Cascades" Kazanlak Branch.

The watershed covers an area of 861 km2, and has an average altitude of ca. 800 m and a mean river gradient of 31.4%. The area is built of granite and granite-gneiss, old Tertiary sediments, diluvial and alluvial deposits. One may find traces of tectonic activities - fissured rocks, dislocation zones with sources of hot spring, etc. Its northern part includes the highest peak of Balkan Mountains, where thick and prolonged snow cover is characteristic. Steep slopes favor surface erosion development.

The lake is about 11 km2 in its surface area and the maximum depth reaches 40 m. It is located in a rich rural region that needs much clean water, and serves to regulate the seasonal turnoff of water supply according to the requirements of consumers - irrigation for fertile fields of both Kazanlak and Stara Zagora, chemical industry in the town of St. Zagora, and hydroelectric power plant.

Lake Dimitrov is also a great local centre for recreation and hot-spring cure because it is surrounded by a number of settlements and dense network of roads. There are good water-sport facilities including a paddle sport base on its northern bank (Q).
