Summary, Etc. Note: |
Abstract: Thermal, oxygen and conductance characteristics are described for two impoundments of the White River in Arkansas and Missouri, from 1963 to 1967. Warming of hypolimnetic waters in Beaver lagged behind that of Bull Shoals owing to epilimnetic turbidity. Annual heat budgets for Bull Shoals were consistently higher than those of Beaver Reservoir; when adjusted for mean depth, heat budgets did not differ significantly from those of natural lakes. Successive annual increases in water transparency, depth of thermocline formation, and oxygen content of underlying waters were evident in new Beaver Reservoir. Oxygen distribution graded from clinograde through orthograde in both reservoirs. Irregular patterns of oxygen distribution were related to the manner in which winter-stored water was depleted or retained. Comparison with other waters for nearly all measurements realted to biological productivity suggests an oligomesotrophic classification. Average conductance of Beaver Reservoir was inversely correlated with inflow volume; in Bull Shoals Reservoir, highest values were in periods of high inflow and water exchange. |
