There are two main problems related to water management in the Upper Narew catchment: it is necessary to increase water resources for supplying the town of Byalystok and increase moisture content of organic soils in the river valleys which were drained for agricultural purposes (irrigation of grassland and reduction of degradation of peat soils). The water reservoir Siemianowka has been construsted for these purpose. It became possible to improve water conditions along the Narew valley including the Narew National Park. However, the problems of water supply for the town of Byalystok and improving water quality in the tributaries of Narew river are not yet solved. It is believed that it is necessary to increase the potential abilities of water retention of small rivers. The studies and approximate calculations carried out show that such measures as increase of swampy areas, the number of water pools and small water reservoirs, damming up of eroded rivers and canals, improvement of soil structure, regulation of outflows from drainage systems, etc.can significantly increase water supply for both the environment and economic and communal needs
