After conducting research, I was unable to find any information about a boat ramp named Omandi Bend in Nebraska. It is possible that the name is misspelled or that this particular boat ramp is not well known or documented.

To accurately discuss a boat ramp, it is important to have specific information about its location, including the county or city it is in. Without this information, it is difficult to determine which body of water the ramp would service or what kind of craft would be permitted on the water.

If more information becomes available about this boat ramp, I would be happy to help provide a detailed discussion about its features and characteristics.
