MATOS - Mid-Atlantic Acoustic Telemetry Observation System

Project Title: Adult River Herring Movements in the Bellamy River (Dover, NH) 2025-2026

MATOS Project Code: V2LBEL

Data Type: Data

Project Duration: April 2025 - on-going

Project Description: River herring can respond positively to barrier removals by recolonizing previously inaccessible stretches of habitat. The Bellamy River in Dover, New Hampshire, has seen two dam removals in 2018 and 2020 that resulted in river herring being observed at an upstream extent that had not been documented in over 100 years of monitoring. However, other potential barriers to river herring migrations, including a culvert, waterfall, and additional dams are still present on the Bellamy River, and passage rates through these barriers and the two recently removed dams remain unknown. By using acoustic telemetry, we will investigate movement patterns, passage rates over each of these barriers and previous dam sites, and the ecological or environmental factors that facilitate or limit river herring upstream and downstream movements. Findings from this project will help inform future restoration efforts in the Bellamy River.
