Springs as groundwater outflows onto the surface belong to permanent elements in Knyszyn Forest Landscape Park which occurrence results from geological structure of Białystok High Plain. Research included 5 springs located in 3 reserves (Krzemianka, Jałówka, Budzisk) in Knyszyn Forest Landscape Park. During research there have been described classification of springs with water analyses of physico-chemical properties as well as flora verification in spring niches. The surveys has shown that in studied area the springs belong to ascending or descending outflows with erosion scarp and rheocrenes at one time. Due to lack of anthropogenic changes as well as location of springs in forest area they possess good water quality here what was proved by water analyses.
