Following up on the previous June 14 post on the longest river originating from each state or province, this post identifies the longest river lying fully within each state or province. Interesting factoids of note from this list:
- Four (4) states where the longest intra-state river matches the state’s name are Alabama, Iowa, Minnesota, and Wisconsin.
- The Sevier River in Utah and Humboldt River in Nevada are the only rivers on the list whose waters never reach an ocean.
- Ontario has two (2) intra-provincial longest rivers with the same length at 610 miles.
- More than half the rivers on the list (33) match the rivers from the June 14 post.
For ease calculating these numbers, those rivers that flow along a state or provincial border are considered being within that particularly jurisdiction. It should be noted that a number of rivers in far-northern Canada appear not have had their mileage fully calculated/published, so for Nunavut in particular, there may be a longer river out there.
The rivers are listed from the longest to the shortest. Peace!
