Distance from Koror: 23 miles (37 kilometers) southwest of Koror, 40-50 minutes by speedboat.
Visibility: Incoming tide: 60 to 120 feet (20 to 40meters). Outgoing tide: 60 to 30 feet (20 to 10
Level of Diving Experience: Novice to Advanced.
Diving Depth Summary: Cleaning station: 55 to 60 feet (18 to 20 meters). Channel Entrance: 10
to 30 feet (3 to 10 meters). Slopes: 15 to 120 feet (5 to 40 meters).
Currents: Incoming tide: the current will flow from the open ocean into the lagoon. Outgoing tide:
the current will carry murky debris laden water from the lagoon to the open ocean. For more
information regarding the tidal patterns in Palau, refer to the Blue Corner tide and current section.
General Information: German Channel is the only channel in the area to funnel the outgoing and
incoming tides from the inner lagoon. The result can be very strong currents through the mouth of
the channel and in the channel itself. Due to fast moving water, a shallow bottom and speeding
boat traffic the channel itself does not offer any diving. The southwest mouth of the channel is
known as the German Channel Dive Site.
Reef Formation: German Channel runs from Northeast to Southwest. The cut through the
western barrier reef between Ngemelis Island and the shallow reef that stretches north of Ngercheu
Island (Carp Island) was done during the German occupation (1899 to 1914) of the islands . The
channel connects the inner lagoon with the open ocean. The open ocean floor, between the two
islands, rises sharply from 1000' (330 m) to 120 feet (40 m) and than gradually to 30 feet (10
meters). The northern and eastern slopes that border the diving areas are covered with large
variety of hard corals. The mouth of the channel has a sandy bottom spotted with numerous coral
heads and coral formations. Marine life: German channel is known for Manta Rays, schooling
sharks and an abundance of tropical fish. Almost every form of marine life can be seen here.
Thousands of jacks will school here along with barracudas, trevaly and snappers of numerous
species. The sandy bottom is home to garden eels, blind Gobies and Mantis shrimps, to name but
a few. During the incoming tide Manta Rays can often be seen inside the shallow channel. In the
late afternoon, the Manta's can usually be found feeding on plankton and krill at the mouth of the
channel. Reef sharks are also known to come to the cleaning station at the mouth of the channel. It
is the lucky diver that gets to see a shark standing vertically with its head thrown back while cleaner
wrasse and butterfly fish hurry to clean its body. Sighting cuttlefish is another reward for the
observant diver. Important Note: Mantas will approach a cleaning station a couple of times before
they hover over the station. At this time the cleaner wrasses and the butterfly fish do their job. If
divers chase the Mantas, the Mantas will leave and not come back!!! Be very patient, let them
come and go; eventually you will get the photo opportunity of your life. Remember, patience is the
name of this game. Keep a distance from the station and let them come to you. The rewards are
worth the wait.
Diving: Two moorings mark the north and south border of the diving area. Your dive guide will
decide where to start the dive according to the current, weather conditions and other boats in the
vicinity. The dive usually starts from the southern buoy. On descent you will see the shallow reef to
one side and a steep slope on the other side. Follow the slope down about 50 feet (17 meters),
keeping the reef to your right. Soon the slope will turn into a very wide sandy plateau. At 60 feet
(20 meters) there is a cluster of large rocks. This is a cleaning station. Swim 15-20 feet away
toward the shallows and wait for the Mantas or sharks. While waiting, look around, if you see large
craters in the sand or between small rocks, you could be in a nesting area of the Triton Triggerfish.
Triton triggerfish are probably the most aggressive fish in theocean. When nesting Triton will attack
any fish or scuba diver that unknowingly enters the nesting area. Looking down at the sand you
can also see blind shrimp lodging together with the Brown Gobi. Watch carefully and you will see
how these two (2) fish work together for mutual benefit. Upon leaving the area swim to the coral
heads and follow them along the sandy bottom. At this point, you will start to sense the German
Channel experience as you are surrounded by schools of fish and patrolling sharks. A wonderful
sight!!!!! Continue along the bottom at 30 to 40 feet (10 to 13 meters) until you reach the slope on
the other side (northern buoy). If the current is strong do not fight it; let it carry you toward the
lagoon. You will, literally, fly over patches of lettuce corals and Giant Tridacna Clams. Before you
surface, listen carefully for the sound of approaching boats. Use a safety sausage to alert boat
drivers to your location in the water. Night Diving: German channel is one of the best areas for
night diving. Both moorings offer excellent vantage points to see night critters. CAUTION: German
Channel is a major passage to the southern dive sites. Dozens of speeding boats cross this narrow
pass daily. Be extremely cautious while ascending to the surface, always mark your spot with a
safety sausage during safety stop.
Fascinating Facts: During the German occupation of Palau, guano (phosphate) was mined on
the southern island of Angaur. In order to bring the guano to town, for trans-shipment to Europe, a
channel had to be excavated. The Germans blasted and dredged a channel through the barrier
reef between Ngemelis and Ngercheu. Today only speedboats and shallow draft vessels can
transit the shallow channel.
