Percent of mussels mobilized by scan visit in the Mission Reach of the San Antonio River, Texas. Percent mobilized is the ratio of mussels that were found displaced during a scan visit compared to the number of mussels that were included in the given study year but not yet mobilized. Scan visits from Year 1 are blue squares and Year 2 are orange circles. The boxed points represent scan visits after similar size flow events for each study year, showing an improvement in percent mobilizations from year to year.
