Laying on her starboard side the seabed is 33m below chart datum at the bow and 34m and stern with the shallowest part of the hull at 20m. The Cöln II is the most intact of the German wrecks. Some deterioration is taking place on the port side plates and two areas have corroded away giving a view of the inside. These are along the edge with the main deck and extend from just in front of the bridge and half way to the bow. The forward guns were removed during salvage work but a gun shield sits on the hull.

The bridge has lost most of it's sheeting, exposing the conning tower. Behind the bridge, the hull where the three funnels were is largely intact. However, there is no evidence of these other than a large debris field on the seabed.

Going astern there is extensive damage around the area of the engine room area from previous salvage work. Once passed this area the stern section is recognisable with its guns.
