Difference betweem postconstruction and preconstruction land surface elevation tins on the Missouri River Downstream from Gavins Point Dam near River Mile 761.4.

This geospatial data set contains an interpolated 3-D surface or, triangulated-irregular network (TIN), of the change in elevation, in feet, of the substrate between cross-sections 23 and 39 following construction of Emergent Sandbar Habitat near River Mile 761.4. 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 761.4 below Gavins Point Dam on the Missouri River in South Dakota before and after construction of the sandbar .
