- Info: Blue Mountain was contracted by the Natural Resource Conservation Service to conduct a watershed assessment. The intent of the effort was to gather resource information about the physical structure and biological function of five rivers, to prioritize treatment areas and to develop management recommendations.
Sixty-five miles of waterways were assessed including portions of the Paria River, Little Creek, Yellow Creek, Henderson Creek and Henrieville Creek. Field assessments included flow duration, Rosgen stream classification and a proper functioning condition evaluation (per BLM TR 1737-15 guidelines). Waterways in this part of the country are characterized by flashy flows and correspondingly high sediment transport and deposition. Lotic conditions in this system were further confounded by historical disturbances, contemporary land use, water depletions and augmentations. Project findings identified areas that were in proper functioning condition and prioritized the treatment of areas that were rated functional-at-risk or non-functional. Recommendations were made and baseline conditions were established in a geo-referenced database to support future management activities. This project involved collaboration with NRCS, BLM, NPS, USGS and private landowners.
