This geospatial data set contains an interpolated 3-D surface or, triangulated-irregular network (TIN), of the substrate surface between cross-sections 22 and 35 following construction of Emergent Sandbar Habitat near River Mile 770. The surface was generated from points collected by the echosounder and real-time kinematic (RTK) GPS on cross-sections in the downstream project reach surrounding the construction area at River Mile 770 below Gavins Point Dam on the Missouri River in South Dakota.
