  Citation × Citation Citation Abstract Copy Title: Little Deschutes Subbasin Watershed Assessment Abstract -- Many of the impacts to fish and wildlife habitat and water quality in the Little Deschutes River Subbasin are concentrated in the areas of housing, roads, and other human development. Most of the human population in the subbasin is concentrated around the community centers of La Pine, Gilchrist, Crescent, and Crescent Lake. There is significant dispersed development along the lower reaches of the Little Deschutes River between the communities of Sunriver and La Pine -an area characterized by gentle topography and depressions with forested wetlands, marshes and shallow lakes. Streams in this area, as illustrated by the Little Deschutes River , are low gradient and originate in the high elevation areas in the southwest portion of the watershed where there is higher precipitation. This ownership pattern has significant implications for natural resource management, as lower gradient floodplain areas tend to provide important wetland, fish, and wildlife habitat. Key Findings Fuel Loading: Having homes safe from wildfires is a concern for many residents. Fire suppression has increased the amount of dry wood in the area, creating a ready source for major wildfires. Riparian Areas and Wetlands: Loss of wetland and riparian areas , especially in the lower areas along the Little Deschutes River , has affected a number of resources. Water quality has been affected by the reduced wetlands that act as filters of nitrogen; the loss of streamside trees and other vegetation reduces shade that helps to cool water temperatures. Finally, loss ofwetlands and riparian vegetation has reduced important fish and wildlife habitats. Wildlife: The growth and development have altered wildlife habitats. Loss of wetlands, streamside vegetation, and other changes in the watershed have reduced important wildlife habitat. Roads and development have impacted migrating mule deer, increasing collisions between deer and cars and altering their migration pathways. Fish: There has been a significant loss of native trout and an increase in introduced brook and brown trout in the Little Deschutes River and tributaries. Loss of native trout is from competition with introduced species and changes in aquatic habitat and water temperatures. Water Quality: A major concern about the water in the river is unusually high temperatures in the summer and the abnormal growth of algae. Other studies indicated that there are problems with groundwater loading ofnitrogen. The high water table (with associated wetlands), and porous pumice soils contributes to increased nitrates, a by-product of septic systems and an indicator of human pathogens.

Final report Author: Enniss, D.O Year: 1980 Interaction of drilling fluids with a geothermal reservoir formation can result in significant permeability impairment and therefore reduced well productivity. This interaction is studied under simulated in situ geothermal conditions of overburden stress, pore fluid pressure, temperature, and pore fluid chemistry. Permeability impairment of an East Mesa KGRA reservoir material is evaluated as a function of stagnation time, drilling fluid, and temperature. Results indicate that all of these parameters contribute significantly to the magnitude and the reversibility of the impairment.

Year: 1976 A process for controlling H/sub 2/S emissions at geothermal power plants was evaluated in laboratory scale equipment and by process engineering analysis. The process is based on scrubbing geothermal steam with a metal salt solution to selectively remove and precipitate the contained H/sub 2/S. The metal sulfide is roasted or oxygen/acid leached to regenerate the metal salt, and sulfur is rejected from the system as elemental sulfur or as sulfate. Up to 95 percent removal of H/sub 2/S from simulated geothermal steams was obtained in a 2'' diameter scrubbing column packed with 3 feet of 5/8'' Flexirings by use of a recirculating slurry of copper sulfate/copper sulfide. Information is included on the chemistry, thermodynamics, kinetics and process control aspects of the process, scrubber system design, operation, and corrosion, and design proposals and cost estimates for a H/sub 2/S removal system.
