​Quadrant provided the engineering design for a project in which the owners of a private ranch and the Idaho Department of Fish and Game entered into an agreement to take advantage of flood-impacted pasture to develop an approximately 600-ft. long side channel reach along the Lemhi River. The primary project objective was to develop a side channel with improved sinuosity and in- stream habitat including large woody debris to improve anadromous fish spawning and rearing habitat within the Lemhi River drainage. The design process utilized a combination of traditional GPS survey mapping and the Bureau of Reclamation’s LiDAR topographic coverage in the area. Quadrant personnel met with local stakeholders on multiple occasions to discuss potential project impacts to existing agricultural practices, and incorporated modifications into the design to accommodate stakeholder concerns.  Quadrant also completed a hydraulic model to verify the flow split ratio between the main river channel and the proposed side channel.  Quadrant worked with IDFG to develop public works bidding documents, provided assistance through the bidding process including pre-bid and pre-construction meetings, and provided construction staking and oversight as necessary through project implementation.
