The marina at which we’re berthed is off Yellow Creek, which is a tributary to the Tennessee River and enters just upstream from Pickwick Lock and Dam. Yellow Creek is also the top end of the Tombigbee-Black Warrior system which leads all the way to the Gulf of Mexico at Mobile, about 400 miles distant. Pickwick Lake is quite large, about 30 miles long and up to 2 miles wide, and is deep enough for our draft. For now we’re a motor boat.
