Overview
Contractor crews replaced a box culvert on Great Dane Creek under State Route 524/Maltby Road near Maltby and rebuilt the nearby streambed to provide a clearer passage for fish like salmon and steelhead. The creek used to pass through a 4-foot wide culvert under SR 524 just west of State Route 9/Woodinville-Snohomish Road. The narrow passage increased the speed of water through the culvert, creating a partial barrier by making it difficult for some fish to swim the creek. The new culvert is 19 feet wide, 8 feet tall and 35 feet long and makes stream flow conditions much easier for all local fish to traverse.
The old Great Dane Creek culvert was one of more than 1,000 culverts subject to a 2013 U.S. District Court ruling that the state must remove culverts that block fish passage under state roads to restore historical tribal fishing rights.
