Kootenay Lake

Abstract Four cores from Kootenay Lake have been dated using 2l0Pb. These cores have also been analyzed for total Pb concentration specifically to compare the sediment record with the known history of lead-zinc mining around the lake. Two sorts of impact on the lake are recorded in the sediments. First, there is obvious contamination by Pb in which concentrations within cores parallel the regional “boom-and-bust” mining history. Second, the sedimentation rate appears to have been affected by damming of the inflowing rivers and probably also by logging and the associated road construction in the watersheds. Spatial variability within the lake sediments is evident: sedimentation rate is highest towards the north and south ends of the lake where river inflow is greatest; contamination by Pb is highest in the middle of the lake close to the major mining activities.

The Impact

<p>During the last 80 years, the Lake Kinneret and its Drainage Basin ecosystems have undergone significant anthropogenic and natural modifications. Man made operations in the drainage basin and in the lake, accompanied by natural climatic conditions, resulted in modifications of the ecosystem structure. Old lake Hula and swamps were dredged and were being converted for agricultural development. Years later, the partial land utilization was modified, in an operation, referred to as the Hula Project operation. Twenty years later, several improvements for the Hula Project structure are suggested. Regimes of nutrient inputs into Lake Kinneret were changed by a decline in Nitrogen influx. Air and epilimnetic water temperature increase, as well as change of the nutrients composition. The lake ecosystem was shifted from P to N limitation. The phytoplankton and fish communities in the lake, were respectively modified. There were enhancements in N<sub>2</sub>-Fixing Cyano-bacteria and Bleak fishes beside the partial decline of tilapias. The impact of Albedo and ENSO (EL-NIÑO/SOUTHERN OSCILLATION) factors is indicated. A combined impact of the natural and anthropogenic parameters are involved. An innovation in the management design within the lake, and the drainage basin ecosystems are suggested: 1: Cutoff of beach vegetation along 20% of the shoreline length enabling public recreation; 2: Intensification of Bleak and improvement of Tilapias fisheries aimed at both, the fishers’ income and the water quality improvement; 3) Slight changes in the Hula Project structure.</p>

Surface Observations

Archaeological reconnaissance and excavations in the Río Balsas drainage basin of Guerrero and Michoacán were undertaken by parties from the University of New Mexico during the summers of 1939 and 1941. As a result of the first summer's work, three publications have appeared. This paper will cover the archaeological remains in the Middle Rio Balsas Basin of Guerrero and Michoacân. It will include the results of both summers' work and be based on surface observations and collections, and on excavations conducted at three sites.For the most part the reconnaissance was undertaken on foot or horseback, inasmuch as the few roads that existed in the area were made impassable for vehicles by the summer rains.

Lake Drainage

A number of studies have examined the effect of forest fires on the nutrient and productivity levels of lakes and streams, but no consistent pattern has been identified. In the specific case of Yellowstone Lake, Romme and Knight (1982) and Albin (1979) suggested that cyclic fires in the Yellowstone Lake drainage basin could potentially increase nutrient loading of the lake and thereby increase its productivity.
