River current velocity measures for select areas of the St. Croix River, 2023-2024 River current velocity measures for select areas of the St. Croix River, 2023-2024
Acoustic Doppler Current Profiler (ADCP) surveys were conducted in October 2023 and August 2024 along several miles of the St. Croix River to measure water current velocities. Although ADCP is commonly used to estimate river discharge, these surveys were designed for a different purpose; therefore, USGS ADCP standards were not followed. Instead, we evaluated alternative approaches to...
Mississippi River Navigation Pool 19 depth & sidescan surveys for site-specific locations, 2024 Mississippi River Navigation Pool 19 depth & sidescan surveys for site-specific locations, 2024
Management of Grass Carp (Ctenopharyngodon Idella) has become of great interest to fisheries managers throughout multiple watersheds where they have become established. Grass Carp baits have been tested as part of an integrated pest management plan to aggregate fish and increase catchability. However, the habitats, water depth, and structures used by Grass Carp remain poorly...
Aerial Camera System Boresight Installation in Bangor, Maine Aerial Camera System Boresight Installation in Bangor, Maine
The US Geological Survey's Upper Midwest Environmental Sciences Center, in coordination with the US Fish and Wildlife Service's (USFWS) Branch of Migratory Bird Surveys, worked to develop, survey, and deploy an advanced aerial photography boresight in the town of Bangor, Maine. The intention of this boresight is to provide an extensive array of high-accuracy ground control points for the
