We have completed 5 consecutive years of scientific studies to determine the health, diversity and abundance of the macroinvertebrate populations of the upper Missouri River from Holter Dam to Cascade as well as 3 years of sampling on selected sites between Fort Logan and Eden Bridge on the Smith River. David Stagliano has conducted these studies in a scientifically professional manner. This has enabled UMOWA to use these studies for presentations to state and federal agencies in order to impress upon them the importance of river flushing flows and its impact on the health of the bug life that is so critical to this important fishery.
