All parties involved in improving fish passage at bridges and culverts agree that a field based method for rapidly assessing passability for prioritization efforts is needed. Several such assessment tools exist; these will be summarized and illustrated so that designers can choose which procedure may be most appropriate for their region.
If you have any techniques that you think will aid others in their efforts to quickly assess culvert passability please send information directly to Rollin Hotchkiss or Chris Frei.
