Utah Division of Wildlife Resources has a list of accessible fishing spots on its webpage.
https://wildlife.utah.gov/accessible-fishing.htmlThe page starts off with "The following is a list of waters that provide fishing access and good fishing to anglers who have physical challenges. Not all of these areas have hard surfaces, and those that do may not meet ADA standards. For more information, call the municipality or agency in charge of the pond or stream, or call the nearest Division of Wildlife Resources office."
Note the hard surfaces issue. If she is in a wheelchair, hard surfaces will help. Wheels and gravel don't mix too well.
