Johnson Creek Watershed Council Success in North Fork of Johnson Creek

The Johnson Creek Watershed Council (JCWC) developed the North Fork Open Migration project conceived as a multi-partner collaboration aimed at eliminating all seven barriers to fish passage in the North Fork of Johnson Creek, near Gresham Oregon. The JCWC worked with a variety of entities to remove, replace and/or repair culverts that were a barrier to fish passage.

In 2018, JCWC made history becoming the first practitioner in North America to utilize the FlexiBaffle culvert retrofit technology to improve fish passage through culverts that are not planned to be replaced. The FlexiBaffle, developed by ATS Environmental from New Zealand creates step pools in a culvert to improve fish passage. Water velocities are reduced, and water depth increased, all to improve fish passage. ATS began working with their partner SSA Environmental to bring their unique fish passage technologies to North America. Since that time, JCWC has installed FlexiBaffles in two additional culverts.

Shane Scott is the principal of SSA Environmental, a Vancouver, Washington-based firm dedicated to protecting fish and other aquatic organisms at bridges, culverts, hydroelectric and diversion dams, municipal water systems, irrigation canals, and pump stations. He leads the development of FlexiBaffle, a flexible retrofit culvert baffle that restores fish-friendly passage (aquatic organism passage) inside existing culverts where a permanent cast-in-place baffle isn't practical. Shane works with state departments of transportation and resource agencies to bring practical, near-term fish-passage solutions to aging culvert infrastructure.
