Julia Cogan
Julia Cogan is a Geographer who has worked at the Upper Midwest Environmental Sciences Center in the Geospatial Sciences and Technologies Branch since 2023.
Julia’s work includes utilizing hydroacoustic technologies to survey freshwater inland river systems, processing hydrographic and topographic data for mapping water depth (bathymetry) and terrestrial elevation, and aerial image interpretation for land cover/land use mapping.

Upper Mississippi River Restoration (UMRR) Program Long Term Resource Monitoring (LTRM) - 2020 LCU Mapping Reed Canarygrass Remap - Upper Mississippi River System (UMRS) Pools 02-13 Upper Mississippi River Restoration (UMRR) Program Long Term Resource Monitoring (LTRM) - 2020 LCU Mapping Reed Canarygrass Remap - Upper Mississippi River System (UMRS) Pools 02-13
Reed canarygrass (Phalaris arundinacea L.) is one of the most common invaders of floodplains in North America. In the Upper Mississippi River floodplain, invasion by reed canarygrass is of primary concern, because reed canarygrass can drive forest loss and inhibit forest regeneration. Knowledge of where reed canarygrass occurs in wet meadow (Wm) and wet meadow shrub (Wms) areas could...
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...
Velocity distribution over a large submersed aquatic vegetation bed for 3 seasons in the Mississippi River, Navigation Pool 13, 2024. Velocity distribution over a large submersed aquatic vegetation bed for 3 seasons in the Mississippi River, Navigation Pool 13, 2024.
This dataset contains data collected with an acoustic Doppler current profiler (ADCP) to measure velocity profiles over a large area with established submersed aquatic vegetation within the impounded area of the Mississippi River Navigation Pool 13, located northeast of Fulton, Illinois. Velocity profiles were obtained using a Xylem brand (San Diego, California) SonTek M9 ADCP for three...
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...
Katahdin Woods and Waters National Monument TFG Unit Vegetation Mapping Project Katahdin Woods and Waters National Monument TFG Unit Vegetation Mapping Project
The Katahdin Woods and Waters (KAWW) National Monument TFG Unit Vegetation Mapping Project was initiated in the fall of 2022 by a grant through the USGS Natural Resource Preservation Program (NRPP) to classify and map vegetation types of the TFG Unit, thereby providing resource managers and biological researchers with useful baseline vegetation information. These data provide the...
Burn Severity Assessment of the 2021 Horne Fire at Isle Royale National Park Burn Severity Assessment of the 2021 Horne Fire at Isle Royale National Park
The 2021 Horne Fire on Isle Royale National Park (ISRO) ignited when lightning struck the island near Duncan Bay on August 10, 2021, during elevated drought conditions. Per the National Park Service, it would continue to burn slowly and spread until a wind event on August 21, 2021 caused significant spread and initiated a control effort to protect historical structures in Tobin Harbor...
