The Brynica River has its sources at 182 m above sea level near the village of Rz?dów (Turawa municipality). Wet meadows and woodland ponds are valuable natural assets of the river in its initial sections. The river’s most valuable part is near Kobylno and Je?owa; further down it loses some of its natural values because of the presence of regulation, cultivated land and urban areas. The Brynica Valley, from Je?owa to Sio?kowice Stare is the border of Stobrawski Landscape Park. South of Nowe Kolnie (Lubsza municipality) Brynica flows into the Budkowiczanka River. The total length of the river is 40,6 km and its basin covers an area of 228,9 km2.
