DESCRIPTION
In partnership with Diking District 13 and the Snohomish Conservation District substantial improvements were made to the tide gate, pump station and riparian buffers along the Swan trail Slough.
Tide-gate and pump station improvements (DOE Centennial Clean Water Fund Grant and Pioneers in Conservation Grant):
• Removed a heavy steel tide-gate that severely restricted anadromous fish access and contributed to degraded water quality conditions with a “fish friendlier”, light-weight aluminum tide-gate to provide improved flow and fish access.
• Replaced the macerating pump with a fish-friendly pump.
• Installed a log boom to reduce debris buildup on the grate, which improves outflows and flushing for water quality improvements.
• Installed water quality and level monitoring equipment at the pump house.
• Planted 700+ plants along the dike near the pump house and along the slough on the Krause property.
Riparian Restoration on Solatka property (DOE Centennial Clean Water Fund Grant):
• Mowed and tilled reed canary grass along the slough on the Solatka property. No herbicides were used per the landowner’s request.
• Planted 2 acres along the slough with 6-ft+ ball and burlap stock western red cedar (Thuja plicata) and Sitka spruce (Picea sitchensis) in curvilinear rows on ~8 ft centers.
• Installed Pacific willow stakes (Salix lucida ssp. Lasiandra) on the banks directly along the slough.
• Installed an irrigation system.
• Maintained plantings as needed.
• Monitored plant vigor, mortality and % cover.
Culvert replacement (Community Salmon Fund Grant)
• A collapsed culvert on the Solatka property was removed and replaced with a bridge
