  Citation × Citation Citation Abstract Copy Title: Yaquina and Alsea River Basins Estuarine Wetland Site Prioritization Project Final Report Abstract -- The project surveyed estuarine wetland sites in the Alsea and Yaquina basins. Sites surveyed were tidal wetlands falling within Jefferson’s (1975) plant community categories of low silt marsh, low sand marsh, sedge marsh, immature high marsh, and mature high marsh. (Mud flats, algal flats and eelgrass beds were not included.) The goal was to prioritize these tidal wetland sites for protection and restoration activity. The information provided by this study provides a basis for working with interested landowners to develop site-specific action plans. Development of these action plans will require landowner contact, field work, and other steps outlined elsewhere in this report.

  Citation × Citation Citation Abstract Copy Title: Clear and Foster Creek Watershed Assessment Abstract -- A watershed assessment was completed in the Clear and Foster Creek watersheds to evaluate existing conditions and make recommendations to protect or enhance watershed natural resources. Clear and Foster Creek are tributaries to the Clackamas River below any major dams on the system; consequently these tributaries are positioned favorably to contribute to recovery of important anadromous fish populations. Anadromous fish species in the Clackamas basin include spring and fall chinook, coho salmon, winter steelhead, summer steelhead (non-native), migratory cutthroat trout and lamprey. Clear and Foster Creeks are utilized by fall chinook, winter steelhead and coho salmon. The assessment generally followed the framework described in the Oregon Watershed Enhancement Board’s Watershed Assessment Manual (WPN, 1999). The assessment focused on the following components: Channel habitat classification and modification; hydrology and water use; riparian/wetlands; sediment sources; water quality; fisheries; and wildlife and upland vegetation. Generally the approach builds on existing information, and enhances this information with aerial photo interpretation and limited field checking. Additional fieldwork was used to verify channel habitat types and to characterize fish habitat condition. GIS was used as a critical assessment tool and method of displaying results.

  Citation × Citation Citation Abstract Copy Title: Bully Creek Watershed Assessment and Strategy Abstract -- This watershed strategy integrates all aspect ofthe subbasin so it views the total system. Historically, natural resource plans have addressed a single problem or only one resource. Coalition members are committed to carrying out this plan, voluntarily, over a period ofdecades. The plan will emphasize "preventive maintenance" instead ofafter-the-fact clean-up. It is the road map to guide private landowners and public-land managers in their efforts to preserve the natural and community resources ofthe Bully Creek subbasin in an economically reasonable manner for all citizens. Implementing the plan will make it possible for public and private land ownerships to achieve improvements ofcontiguous habitats.

  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.

Year: 1978 The Coso Geothermal Exploration Hole number one (CGEH-1) was drilled in the Coso Hot Springs KGRA, California, from September 2 to December 2, 1977. Chip samples were collected at ten foot intervals and extensive geophysical logging surveys were conducted to document the geologic character of the geothermal system as penetrated by CGEH-1. The major rock units encountered include a mafic metamorphic sequence and a leucogranite which intruded the metamorphic rocks. Only weak hydrothermal alteration was noted in these rocks. Drillhole surveys and drilling rate data indicate that the geothermal system is structurally controlled and that the drillhole itself was strongly influenced by structural zones. Water chemistry indicates that this geothermal resource is a hot-water rather than a vapor-dominated system. Several geophysical logs were employed to characterize the drillhole geology. The natural gamma and neutron porosity logs indicate gross rock type and the acoustics logs indicate fractured rock and potentially permeable zones. A series of temperature logs run as a function of time during and after the completion of drilling were most useful in delineating the zones of maximum heat flux. Convective heat flow and temperatures greater than 350/sup 0/F appear to occur only along an open fracture system encountered between depths of 1850 and 2775 feet.

Because of the high cost of completing wells into these formations and their relatively low temperatures (200 to 400 F), the utilization of the geothermal energy will be highly depend on, and of secondary importance to, the value of the methane. The economics of extracting either the geothermal energy or natural gas from these aquifers does not look promising. The combined requirements of high well flow rates (40,000 bbl/day), long life (20 years), and the necessity for close well spacing to minimize the cost of the collection system may be incompatible with the actual characteristics of the reservoirs.

The ordinance contains provisions for: community geothermal development and utilization policies; a municipal geothermal district heating service; reservoir monitoring and management procedures and authorization for private geothermal heating services. The ordinance's "preliminary" nature is due to two pending legal issues on the state level: first, a revision of thermal ground water Administrative Rules is being prepared by the Oregon Water Resources Department; and second, the Oregon Governor and Legislature are considering an Alternate Energy Development Commission recommendation to develop a program whereby geothermal heating districts will be involved in the cooperative management of local thermal ground water reservoirs with the Oregon Water Resources Department. However, neither matter is expected to be finalized until 1981. Both geothermal fluids and ground water are cited jointly throughout the ordinance because of the legal definition of low to moderate temperature fluids as ground water, and the potential for the Klamath Falls community to encounter high temperature resources defined as geothermal fluids.
