Macroinvertebrate Studies
Scientific investigations into the health of aquatic insect populations
Over a Decade of Scientific Research
UMOWA has conducted over a decade of scientific investigations (2015–2025) examining the health, diversity, and abundance of macroinvertebrate populations from Holter Dam to Cascade, plus four years of sampling on specific Smith River sites between Fort Logan and Eden Bridge (2016, 2017, 2018, and 2024).
David Stagliano conducted these studies using scientifically rigorous methodology, enabling UMOWA to present findings to state and federal agencies demonstrating the significance of river flushing flows for maintaining healthy aquatic ecosystems.
