15 Mile Reach Topobathymetric LiDAR Collection

The State of Colorado, Department of Natural Resources, is seeking a contractor to collect topobathymetric LiDAR data for the 15 Mile Reach of the Colorado River. The data will be used to support 2D HEC-RAS modeling focused on habitat assessments. The contractor will be responsible for acquiring high-resolution topobathymetric LiDAR data, supplementing it with boat-mounted sonar data, and collecting imagery. The project is expected to start on December 15, 2025, and be completed by August 1, 2026, with a possible extension of up to six months. • The contractor will acquire LiDAR data on cloud-free days with the sun at a sufficient angle to reduce shadows and glare. • The contractor will supplement LiDAR data with boat-mounted sonar data. • The contractor will collect imagery in combination with LiDAR data. • The contractor will provide a project summary report, topobathymetric LiDAR and sonar data, digital elevation model, and imagery. • The contractor will ensure that the area of interest is fully and sufficiently covered with no data voids.
