Determination of habitat availability, habitat use, and flow needs of endangered fishes in the Yampa River between August and October The goal of this study is to define the baseflow needs of endangered fish populations in the Yampa River. The approach taken was to simulate habitat availability associated with several low flow scenarios and relate changes in habitat availability to habitat use by endangered fishes.

A Study of the Ecological Processes on the Fryingpan and Roaring Fork Rivers Related to Operation of Ruedi Reservoir - Final Report This study was conducted on the Fryingpan and Roaring Fork rivers to characterize the physical habitat and aquatic biota related to the operation of Ruedi Reservoir. The study components included instream habitat and flow relationships, thermal regime of reservoir releases, characterization of spawning habitat, and investigations into benthic macroinvertebrate populations and fish populations.

A Study of the Ecological Processes on the Fryingpan and Roaring Fork Rivers Related to Operation of Ruedi Reservoir - Supplemental Report The mechanisms that govern the structure and function of benthic macroinvertebrate communities in the Fryingpan River are not entirely understood. For this reason, sampling continued during the Fall 2002 and Spring 2003 as a supplement to the study that occurred during the previous seasons (Ptacek et al. 2003). Releases from the impoundment at Ruedi Reservoir directly influence the benthic macroinvertebrate and fish communities that exist downstream. The influence of regulated discharge on the macroinvertebrate community can result in an increase in thermal stability and extended periods of flow stability. However, it is unknown how the level of discharge during the winter months and the potential formation of anchor... Categories: Publication; Types: Citation
