Abstract/Description or Keywords |
A total of 103 crossing structures were found to require inspection. Of those, sixty-one were close bottomed structures (CBS), thirty-four were open bottomed structures (OBS), and 8 were Other (i.e. Fords). 539 km of road were anticipated for inspection, and 547 km were available including new smaller roads. Group A included 47 CBS, 15 OBS, and 7 Others. The average fish passage score for CBS here was 25, and all but one CBS structures required replacement or were potential barriers. The average HGI for group A was 0.29, indicating very little additional habitat was available upstream of the crossing locations. Group B included 14 CBS, 18 OBS, and 1 Other. The average fish passage score was 28 on the CBS in this group, and they all were scored as potential or total barriers to fish passage. The average HGI for group B was 0.68, indicating little additional habitat was available upstream of the crossing locations.
