Iron Woman completed a $4.3M resilient river restoration project along three reaches of Left Hand Creek, located at the intersection of Highway 36 and Lefthand Canyon Drive in Boulder County. Working with the Lefthand Canyon Oversight Group, Iron Woman provided mitigation and recovery efforts for the partially federally-funded project that is part of the Watershed Resilience & NRCS Emergency Watershed Protection Implementation Program.
Iron Woman’s work included removing, grading, and benching sediment to stabilize the main channel and improve floodplain connectivity; shaping and rehabilitating the channel and forming step pools along the reach; providing bank stabilization and protection in three discrete areas; constructing and repairing berms, enhancing the bed-form and repairing the head cut; and creating overflow channels to increase conveyance during high flow.
Iron Woman installed buried rock revetments to protect buildings and ditch diversion structures, installed a stormwater swale and offset protection near certain dwellings, developed in-stream habitat enhancements to increase habitat complexity and connectivity, and removed debris and dead trees.
