Predicted specific minimum flow of small streams in the Upper Colorado River Basin based on historic flow data Our objective was to model specific minimum flow (mean of the annual minimum flows divided by drainage area [cubic feet per second per square mile]) on small, ungaged streams in the Upper Colorado River Basin. Modeling streamflows is an important tool for understanding landscape-scale drivers of flow and estimating flows where there are no gaged records. We focused our study in the Upper Colorado River Basin, a region that is not only critical for water resources but also projected to experience large future climate shifts toward a drier climate. We used a random forest modeling approach to model the relation between specific minimum flow on gaged streams (115 gages) and environmental variables. We then projected...

Upper Colorado River Basin, Fewer tags Generalized 1:500,000-scale geology of the Upper Colorado River Basin This generalized geology dataset was developed as input to a total dissolved solids Spatially Referenced Regressions on Watershed Attributes (SPARROW) model for the Upper Colorado River Basin (UCRB; Kenney and others, 2009) and for a more recent update to that model. The largest source of naturally generated dissolved solids in streams of the UCRB is the rocks underlying stream basins, particularly rocks high in dissolvable minerals. For the purposes of modeling, the scale of the geologic dataset optimally should be similar to the scale of the stream-catchment network used in the model but simplified to reduce the number of geologic units represented in the data. This dataset was developed to meet both scale and...

Categories: Data; Types: Citation; Tags: Upper Colorado River Basin, climate change, groundwater recharge Science-Based Riparian Restoration Planning on the Colorado and Dolores Rivers: A Decision Support Tool and Investigation of Habitat Complexity at Tributary Junctions Stream flow in the Colorado River and Dolores River corridors has been significantly modified by water management, and continued flow alteration is anticipated in future decades with projected increases in human water demand. Bottomland vegetation has been altered as well, with invasion of non-native species, increases in wildfire and human disturbance, and currently, rapid shifts in riparian communities due to biological and mechanical tamarisk control efforts. In light of these conditions, land managers are in need of scientific information to support management of vegetation communities for values such as healthy populations of sensitive fish and wildlife species and human recreation. We propose to address these...
