current understanding - there are only 2 years of data that use mark recapture methods.
Reviewed email chain. They have 4 years where they applied CJS, however they only provided totals. Could be useful to compare with upstream passage. They consider their upstream passage a census. 2014: 2,569 2015: 1,652
2019: 678 2020: 395
