Evaluation: 3-stage evaluation for each artificial structure (continuity [passing rate ≥50%], damaged [50%> passing rate >0%], discontinuity [passing rate=0%]). Total: better passing rate between 1st and 2nd investigation. -: structure no exist (but registered in the fishway information system [Ministry of Oceans and Fisheries, 2023]).
DC, dorimcheon (artificial structure name in Dorim river).

Evaluation: 3-stage evaluation for each artificial structure (continuity [passing rate ≥50%], damaged [50%> passing rate >0%], discontinuity [passing rate=0%]). Total: better passing rate between 1st and 2nd investigation. -: structure no exist (but registered in the fishway information system [ DC, dorimcheon (artificial structure name in Dorim river). Evaluate qualitatively.
