Kuźnica Warężyńska water reservoir

PROJECT DESCRIPTION:

The Kuźnica Warężyńska water storage reservoir (commonly called Pogoria IV) was created in the excavation of the sand mine, as a form of rehabilitation of the grounds degraded by opencast mining. Kuznica Warezynska together with the Przeczyce and Pogoria III reservoirs form a system of retention reservoirs in the Czarna Przemsza River basin. Beside their recreational function, they ensure a biological flow in the Black Przemsza River, flood protection of the river valley downstream the reservoirs, including the towns of Bedzin, Sosnowiec, Myslowice and Jaworzno (4x reduction in potential flood flows), as well as water supply, and the potential for fishery development.

TECHNICAL DATA:

• total capacity of the reservoir reaches 51.16 mln m³, including flood reserve of 8.07 mln m³
• surface of the reservoir at the maximum water level covers 560 ha
• maximum depth reaches 20 m
• earth dam of 250-m length and max height of 6.8 m
• three-span weir with the flap gates 3 x 3.0 m
• side dams 950 m long
