Construction of several dams for an irrigation diversion had raised the water level by 8 ft, creating a sediment trap and a fish barrier. Riverbend Engineering conducted topographic and stream morphology surveys for the Upper Pecos Watershed Association (UPWA), and proposed a design for the active river channel that would be morphologically stable. The irrigation diversion intake was relocated upstream, reconstructed with large boulders and a sediment sluice was added to the headbox. A series of smaller grade control structures allow for a flatter overall river profile, restoring fish passage and improving sediment transport continuity.
