Short summary
We analyzed eight years of citizen science data from a creek in Montana, USA to understand the impacts of small dam removal and explore the quality of citizen scientist stream monitoring. Volunteers measured sediments and counted aquatic insects at sites above and below the dam before and after its removal. We found the citizen scientists collected high-quality data that showed no change in stream health following dam removal. We highlight key practices for successful citizen science monitoring.
