POST No. 1 - Here is the set up: From the U.S. Army Corps of Engineers - 33 CFR Part 329 - Definition of Navigable waters of the U.S. Section 329.4 - General definition Navigable waters of the United States are those waters that are subject to the ebb and flow of the tide and/or are presently used, or have been used in the past, or may be susceptible for use to transport interstate or foreign commerce. A determination of navigability, once made, applies laterally over the entire surface of the waterbody, and is not extinguished by later actions or events which impede or destroy navigable capacity. http://www.usace.army.mil/inet/functions/cw/cecwo/reg/33cfr329.htm Great Lake Elevations (average elevation) Superior - 600 feet Michigan and Huron - 580 feet Erie - 570 feet Ontario- 245 feet Not all that high, and not all in the U.S. Now See post no. 2...

POST No. 2 - please read post no. 1 first Based on the definition from the previous post, and the Missouri and Columbia Rivers once being used for interstate and foreign trading, I give you The Highest Navigable Lakes in the U.S. (at least that I could find) LAKE OAHE, the 4th-largest man-made reservoir in the United States, extends from Pierre, South Dakota to Bismarck, North Dakota. The lake is 231 miles long, has 2250 miles of shoreline, and has a maximum depth of 205 feet. (Missouri River) http://www.nwo.usace.army.mil/html/Lake_Proj/oahe.htm Average elevation: 1608 feet. http://www.mrd.usace.army.mil/rcc/plots/pixel/oahe.gif LAKE SAKAKAWEA (Garrison Dam Reservoir) Missouri River, North Dakota elevation 1634 feet http://www.mrd.usace.army.mil/rcc/plots/pixel/garr.gif FORT PECK LAKE, Montana (Missouri River) 2222 feet http://www.mrd.usace.army.mil/rcc/plots/pixel/ftpk.gif CANYON FERRY LAKE, Montana (Missouri River) 3788 feet http://www.mrd.usace.army.mil/rcc/plots/pixel/cafe.gif FRANKLIN D. ROOSEVELT LAKE -1284 feet -formed by the Grand Coulee Dam on the Columbia River, in Washington state. The Columbia had been used by explorers and traders for the Hudson Bay Co. and the Northwest Trading Co. Therefore, by definition, it is a navigable lake. http://www.nps.gov/laro/ Happy boating!
