Abstract:: A steady-state phosphorus cycle was determined for the stratified period May to November in Lake Sammamish, Washington. A steady-state. condition for this period is considered at this time since data on some important processes are only sufficient to estimate average values for the stratified period. Nevertheless, such a cycle is...

Abstract:: Aquatic mineral measurements and sediment characterization of the Cedar River basin lakes and streams reveals two largely distinct physical and chemical environments. Near the headwaters of the Cedar River Watershed the composition of lakes and streams reflect adjacent rocks but the effects of forest and agricultural practices and of processes...

Abstract:: The objectives for year have been the gathering of existing information, initiation of monitoring water quality, evaluation of analytical methods and procedures for measuring nutrient regeneration in the sediment-water interface, and the study of growth-environment correlations in Findley Lake, Chester Morse Reservoir, and Lakes Sammamish and Washington. Progress was made...

Abstract:: One of the major objectives of the Western. Coniferous Biome is to understand the relation between terrestrial ecosystems and the chemical and biological properties of drainage waters. The first year of study on such a program has been completed and has primarily entailed a year of descriptive studies.

Abstract:: Grazing rates and density of the crustacean zooplankton were measured in Findley and Chester Morse Lakes and Lake Sammamish, Washington. Sample analysis is incomplete at reporting time, thus estimates of production from examination of life stage biomass changes was not possible. Maximum density of crustacean zooplankton was about 10/1 in...

Abstract:: Lakes Findley, Chester Morse and Sammamish, Washington, are characterized by one major outburst of phytoplankton productivity and biomass (mainly diatoms) with usually no or low fall activity. Vernal outbursts were often delayed in some lakes and years probably by unfavorable climate (snow cover and cloudy rainy conditions). Mean spring-summer productivity...

Abstract:: The feasibility and enumeration studies have led to the following conclusions: The nitrogen fixation studies should be done in 1973, using acetylene reduction technique with some verification by N15. The denitrification studies should be done with N15 technique. The decision to continue more enumeration sampling of nitrogen transforming bacteria should...

Abstract:: Macrobenthos populations of the IBP lakes were sampled during October and November of 1972. Analyses of the samples revealed dominance of chrinomids and oligochaetes in both littoral and profundal regions for at least this time of year. Due to sampling difficulties the oligochaete material was not used for chemical analyses....
