The paper presents the history of water conditions in the catchment area of the river Tyśmienica. On the basis of topographic maps in scale 1 : 100 000 1839 to 2009, and drainage projects presents the changes of the water network. In the middle 19th century, the river took the start from the lake Krzczeń, and major reclamation works were performed at the turn of the century. In the seventeenth century, built the largest pond Siemień. The development of the joint occurred after World One War because the existence of joints protect assets before breaking up.

In the 60’s the water channel beginning the Tyśmienica led passing to the east of Lake Krzczeń and Rogóźno.
