The horizontal distribution and vertical migrations of the limnetic zooplankton in Crater Lake, Oregon

Creator:: Hoffman, F. Owen
Abstract:: During the summers of 1967 and 1968 the horizontal distribution and did vertical migrations of zooplankton were studied within the unique environment of Crater Lake. Sampling of the horizontal distribution was done by towing plankton nets vertically in different locations. The vertical distribution was sampled by towing at different depths...

The species composition, density, and distribution of the littoral zooplankton assemblage in Crater Lake, Oregon

Creator:: Warncke, William Madara
Abstract:: The species compositions and densities of the littoral and pelagic zooplankton assemblages in Crater Lake were compared. The littoral and pelagic zooplankton assemblages of most lakes are typically different due to different habitat conditions in the two zones. The littoral zone of Crater Lake lacks many of the habitat characteristics,...

The vegetation dynamics of Pinus contorta forest, Crater Lake National Park, Oregon

Creator:: Zeigler, Robert S.
Abstract:: This study describes the soils, vegetation and age structure of the Pinus contorta forests of Crater Lake National Park. Growth rates of P. contorta, and levels of infection and impact of dwarf mistletoe (Arceuthobium americanu1r) on growth of P. contorta individuals are compared among communities. Vegetation description is based on...

Benthic macroinvertebrates and sediment characteristics of a coastal dune margin lake (Carter Lake, Douglas County, Oregon)

Creator:: Wones, Andrew G.
Abstract:: Carter Lake, a freshwater, coastal dune-margin lake, was sampled at the beginning and end of the summer of 1986 to determine the sediment characteristics and benthic macroinvertebrate abundance, biomass, variety, and diversity. The distributions of major benthic habitats were estimated by snorkeling in June and July, 1986. Water temperature and...

Dispersed winter recreation use patterns and visitor attitudes at Crater Lake - Diamond Lake, Oregon

Creator:: Thompson, Terry Jo
Abstract:: Winter recreation has increased rapidly in the Crater Lake - Diamond Lake area of Oregon in recent years. Park and forest managers are concerned about existing and potential impacts of the recreationists on the resources and other recreationists. The purpose of this study was to describe the nature and extent...

Ecology of kokanee salmon and rainbow trout in Crater Lake, a deep ultraoligotrophic caldera lake (Oregon)

Creator:: Buktenica, Mark W.
Abstract:: Crater Lake, originally barren of fish, was stocked on an irregular basis from 1888 through 1941 with several species of salmonids. Two species occur in the lake today--kokanee salmon (Oncorhynchus nerka) and rainbow trout (Salmo gairdneri). This study was initiated in the summer of 1986 to evaluate the ecology of...

Mount Mazama and Crater Lake : A Study of the Botanical and Human Responses to a Geologic Event

Creator:: Green, Robyn A.
Abstract:: Crater Lake, located in the southern Cascade mountains of Oregon, is the seventh deepest lake in the world. Unlike a majority of the deepest lakes in the world, found in continental rift valleys, Crater Lake is in the caldera of a volcano. For the young at heart and mind, those...

Infiltration and temperature characterization of a wastewater hyporheic discharge system

Creator:: Stewart, Ryan D.
Abstract:: The Clean Water Act imposes Total Maximum Daily Load (TMDL) limits on pollutant concentrations within wastewater effluent; in Oregon, thermal discharge is one of the pollutants subject to regulation. The City of Woodburn, Oregon, funded a series of pilot scale studies to investigate the utility of natural systems to reduce...
