Bathymetry data for the post-construction survey of the Emergent Sandbar Habitat project at river mile 761.4 downstream from Gavins Point dam on the Missouri River.

This geospatial data set contains the points collected by the echosounder on transects 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. This survey provides channel cross sections for new and selected existing transects following construction of Emergent Sandbar Habitat near River Mile 761.4

本地理空间数据集收录了南达科他州密苏里河加文斯角大坝下游761.4河英里（River Mile）处施工区域周边项目下游河段内，回声测深仪（echosounder）在断面（transects）上采集的点位数据。本次勘测于761.4河英里附近挺水沙洲栖息地（Emergent Sandbar Habitat）建成后开展，为新增断面与选定的原有断面提供了河道横断面数据。
