In 2016 Cascade Fisheries removed a 100% fish passage barrier culvert and replaced with a bottomless arch culvert, restoring fish passage. In 2017 CCFEG removed two fish passage barriers culverts that were 30% and 100% barriers. These culverts were replaced each with 40 foot steel bridges. All three sites were on privately owned driveways.
