The California Delta is one of the best boating and recreation areas for people to meet, boat, drink, eat and have a lot of fun. There are so many restaurants and bars, beaches and just great places to hang out on the water if you so desire. A couple of the places I have found that are hotboat friendly are the next few routes I have completed myself and waypointed to get mileages for fuel. Check them out
So this top chart shows leaving WIMPYS MARINA located at 14001 W Walnut Grove Rd in Walnut Grove listed as #7. New Hope Landing is #4 Then follow the route south to Tower Park which is just at the end of the S. Mokelumne River and is shown as #25 on the bottom chart. Just stay RIGHT all the way down the river and you cant get lost. Once you see the Hwy 12 bridge you will see Tower Park Marina. They have Fuel, Food, and anything you need. A short 5 mph zone and your out to the Potatoe Slough.
Follow the Potatoe Slough out to Little Potatoe, this is a hard right turn almost a reverse turnaround.Then to the San Joaquin River, for a very short distance to the N. Mokelumne River inlet and head North.Right past B&W Resort is the inlet to the Georgianna Slough and head North. Goergianna has a large residential community with lots of homes along the shore and very friendly people willing to share their BBQ and beers with you. Be a good person and enjoy all they have to offer while cruising thru their neighborhood!
After Oxbow Marina (Last Fuel Stop Avail to Walnut Grove) it opens up a bit and you can fly that Flat as hard as you want. The last mile or two is another 5mph zone before it meets the bridge to Walnut Grove. Its wide open area with no peoples around. Once in Walnut Grove you can stop for more treats or beverages at any of the towns eaterys, pizza is good there and Tonys Bar is within walking distance too. Make sure the GATES are open to the upper N. Mokelumne and thats where you go thru to Dead Horse Slough and back to Wimpys.
