The lake is surrounded by Bundek Park which stretches for 2,000 meters in length with an area of 35 hectares. The lake is about 5 hectares. the lake was initially used for fishing, walking and swimming.

People of all ages, the majority between age 30 and 40, from Prečko and neighbouring districts are involved with the garden (Ref 4).
Guadaira Park
A recovered green area next to the Guadaira river, it opened as a park in 2014 (Ref 6). In its planning it reconciles the historical use of the river to power the historic mill and its new use as a green corridor on the Eastern part of the city. Its large dimension allows it to fulfill the quadruple ecological, landscape, leisure, and non-motorized mobility dimensions. (Ref 4,5,6). The park was officially inaugurated but it continues to face challenges. In 2007 the economic crisis led to construction being stopped and the budget of the park cut from 23.8 million euro. Construction was started and the budget re-established at 17.2 million in 2011. (Ref 5)
