Summary
This dataset represents elevation data of the beach topography and near-shore bathymetry before placing dredge spoils on the beach at Minnesota Point near the Duluth Entry of Lake Superior, Duluth, Minnesota. The data was acquired using a lidar sensor, single-beam and multibeam sonars. The dataset includes DEMs of the terrestrial beach areas and topobathy (combined terrestrial and bathymetry), LAS and XYZ files of lidar, single-beam, and multibeam point data, and 2-ft contours. Data were collected in cooperation with the U.S. Army Corps of Engineers (USACE), Detroit District, to evaluate movement of placed material and overall change of near-shore bathymetry after beach nourishment.

Data were collected in cooperation with the U.S. Army Corps of Engineers (USACE), Detroit District, to define beach topography and near-shore bathymetry prior to beach nourishment in areas of Minnesota Point near the Duluth Entry to Lake Superior that have been scoured by high water levels and heavy wave activity. This survey was completed to obtain baseline data and establish pre-nourishment conditions before placing dredge spoils to mitigate beach erosion in September 2021.
