In this assessment, the size of the flood pulse and resulting fish
recruitment is assumed to be unaltered by the run-of-river dams
(even though some additional impacts are likely). The main impact
is assumed to be the prevention of migration for the fish that
depend on these conditions and a concomitant reduction in
recruitment and catch. Furthermore, we have not calculated the
land-based protein sources that would be lost with the inundation
of 1350 km2 of riverside lands.
