A quick summary of gas options for the Lower Mississippi:
From Hoppies (mile 158) just below St Louis it is 387 miles to Mud Island Marina (mile 735) in Memphis.
You can cut 41 miles off of this with a stop in Evansville on the Kaskaskia River, 11 miles off river at mile 117. There is a small lock into the Kaskaskia. There is gas and food at the marina. There is a small grocery store in Evansville, Illinois a short walk from the marina.
If you can't quite make the 346 miles from Evansville to Memphis, you have the following gas options:
It is a modest walk to get gas in cans at mile (921 1/2) in Hickman Ky. On the
left descending bank up a side inlet about 1/2 mile off river
or a short walk at mile 889 right descending bank at New Madrid Mo.
Kidd's (delivery) in Cape Girardeau (mile51)is hit and miss, Hoppie or his wife usually know the latest as to the fuel availability in Cape Girardeau.
Gas is available at Mud Island Marina in Memphis (mile736) If you do no other sightseeing do the River exhibit and museums at Mud Island in Memphis.
After Memphis gas is available at the marina in Greenville, MS. (Mile 537), 4 miles off river up an old channel. Casino next door. Several block walk into town to small store
You can tank up again in Vicksburg (mile 437) left bank 1 mile up old river channel, cans and short walk. There is enough activity at Vicksburg that someone with a pickup truck will usually give you a ride. Nice restaurants and historic sightseeing in walking distance. Wireless internet
It is another long run of about 340 miles to New Orleans, No on river services or gas in New Orleans. We left the river in New Orleans to Lake Pontchartrain at the Industrial Canal (mile 92.5) there is a marina with gas a few miles down the canal.
To make this stretch your 3 gas options are Natchez (mile 363) walkable, There is a bar and restaurant on the Natchez side. A casino is also on Natchez side. On the opposite bank is Vidalia, La. Nice hotel right on the river and a nice new park with boat ramp at Vidalia. Its pretty easy to get a ride for gas at Natchez or Vidalia.
St Francisville ferry landing (mile 266), you must get a ride, it’s a bit too far to walk. or Weber marine (mile 167) Weber marine is a barge terminal but the owner has a soft spot for river runners and will usually have an employee give you a ride for gas and groceries, They are open 24 hours and usually will let you tie off for the night to one of the barges. Next gas is the Marina in the Industrial canal (mile 92.5)
We did not go the last 92 miles to the gulf so have no info on that stretch, but we believe there is gas at Venice.
