Tom & Nancy - Am echoing Jason's comments. For the last two seasons, I have never seen all the slips filled, even on the busiest weekends.
The marina is organized with docks for government boats at one end and then docks for Zanterra cruise ships (one big one for short guided tours, and the other for runs on the lake to fish with say up to 8 persons. Five (5) Grady-White 22' boats where guides take fisherman out for hourly trips are berthed, and then 16' rental boats with 40HP Hondas and 14' rental row boats are also in slips.
The leased docks begin on dock B, which is called a transient dock, with slips on both sides. I choose to lease on B dock because it is rarely busy and affords more privacy.
The other docks C,D,E. etc. are usually filled up with bigger boats - maximum 40'. All the docks are beautifully constructed and each slip has its own electrical hookup and potable water from a lighted (at night) tower. Cleats are strategically located to assist in tying up.
Wheeled carts are available on the docks for moving supplies to the boats.
Cars and pickups of boaters are allowed to drive to the edge of the docks to help in unloading. Then the vehicles are required to return to the paved parking lot for parking. Also, after launching, your trailer can be dropped on one side of the parking lot. The parking lot is quite large and accommodating.
Xanterra provides security even at night time. Only boaters and their guests are allowed on the docks. Heated bathrooms (but only cold water) and flush toilets are near the launch site at the ranger station overlooking the slips. Also, the marina office is located along side with a well stocked food and supply store, coffee, etc.
Near the government dock is a separate fuel dock with tie ups on both sides. Hot showers are located at Fishing Bridge trailer court a few miles away. No generators are allowed to run after 10 pm, and the marina is very quiet at night because all the motorized tourists are gone. The dock area is immaculate - no discharge in the lake whatsoever is allowed including gray water. Fish must be cleaned at a nearby cleaning station.
Bridge Bay Marina office can be reached at 307 - 242 -3876 for reservations, 9-5. 2010 summer rates per night for 16'1" and over are $23.00. The monthly rate for 20'1" to 25' is $303.00.
If you should arrive after the ranger station and marina offices are closed, just find an open slip on B dock and berth. You can take care of the necessary paper work in the morning since the offices are open daily.
For meals, you can cook aboard, go to the lake hotel area (a few miles away) and dine fancy or go to a large cafeteria nearby. Also the lake area store has a fast food service, and marina store has fast food and is open to 9 pm.
Hopes this gives you some useful information in planning your trip and any other C-Dog coming this way.
