Weather…

Modrac Lake is one of the largest artificial reservoirs in northeastern Bosnia and Herzegovina, located near the town of Lukavac and the city of Tuzla. It was established in 1964 with the construction of a dam on the Spreča River, primarily to supply water for the surrounding heavy industries and the local population. Spanning an area of approximately 17 square kilometers, the lake serves as a significant ecosystem and was once the premier tourist destination in the region. The average depth is relatively shallow, which has fostered a rich variety of aquatic flora and fauna along its shores. Over the past few decades, the lake has faced substantial environmental challenges due to industrial runoff and sedimentation, prompting various ecological restoration initiatives. Despite these issues, Modrac Lake remains a popular site for recreational fishing, known for its pike and pike-perch, as well as a weekend getaway for residents of the Tuzla metropolitan area. The lakeside promenades and facilities are remnants of its heyday as the "Sea of Tuzla," illustrating ongoing attempts to promote sustainable tourism.
