| Summary: | The aim of the study was recognizing the hydrotechnical infrastructure and metallurgical activity and changes in the structure of land use and its hydrographic network of the Czarna Konecka total catchment, and in Integrated Water Surface Parts (SCWP): SW0709, SW0710, SW0711 over the last 200 years. The analysis was based on a comparative analysis of cartographic material from various research periods. The development of the metallurgical industry in the period from the beginning of the 19th c. to the first half of the 20th c. caused a decrease in the forest's share in land cover and an increase in the length of watercourses. In the next 100 years, the area designated for renewal increased, but the species structure of the trees changed almost completely. Conifers were mainly used for afforestation. The increase in the length of watercourses was caused by the construction of drainage ditches, millers for the needs of water mills, mills, sawmills and for agriculture. In addition, many sections of the rivers were regulated and straightened. At the same time, due to the termination of many industrial plants, the area of water reservoirs drastically decreased until the first half of the 20th c. Many of them have been drained, or have been partially or completely silted up by sediments flowing in by rivers. The increase in standing water surface in the last about 100 years was caused by the construction of new water reservoirs, mainly for breeding ponds.
