The data required to run FishXing is largely based on the culvert and the hydrology of the crossing. Swim Speeds can be selected from the database and adjusted based on experience and judgement. If fish performance data is available FishXing can accommodate custom data and agency criteria or guidelines.  

See the Crossing Input Window for more information about specific data fields in the software.
