The Teltow channel is a shipping channel that flows crosswise through Berlin. In addition, a ca.6 kilometer long section is situated in Brandenburg. This area can be divided into two sections, because there is a lock Kleinmachnow. The areas directly over and under the lock are the best places. Worth mentioning is also the Machnower lake, by which the Teltowkanal flows. The lake is relatively flat and muddy, so that the best places are at the in and discharge. The channel is between 60 and 120 feet wide and about 13 feet. The fish stock is quite good, even if the small carps are in the majority. In the Teltow channel already fish about 42 lbs were caught. Underneath the lock already large catfish were caught.
