Summary

Subbottom profiling of the sediments in Turkey Lake and Little Turkey Lake (and 11 others in eastern Ontario and Quebec) using an acoustic profiler is reported. Profiles showed that many lake bottoms are filled with more than 25 m of lake glacial sediment which is generally covered in turn by up to 5 m of modern gyttja-like lake sediment.

Summary

Gives background information on acidic precipitation, potential effects on forests in general and to the forest type in the TLW in particular, and other physical characteristics of the TLW basin.

Summary

Report presents results of a survey of 85 headwater lakes in which an attempt is made to recognize relationships which may exist between the well-being of biological communities and chemical status. Biological communities reflected to varying degrees the acidic status of their aquatic habitat. Compared to plankton and benthic organisms, fish provide the most blatant response to changes in their habitat.

Summary

Distribution and physical characteristics of both modern and unconsolidated glacial sediments are reported for the material in the bottom of 4 shield lakes including Turkey and L. Turkey Lakes. Three to 5 m of gyttja overlies bedrock and glacial sediments in all but the steepest part of the lake basins. Anomalously high carbonate content in the drift adjacent to the lakes is reported.

Summary

Report summarizes causes of acid precipitation and effects on forest soils, namely leaching of basin cations, changes in nutrient availability, and alteration of microbial decomposition. Report is essentially a public information sheet.

Summary

Two areas, Algoma and Ranger Lake are discussed in this report. The Algoma component which includes the TLW is designed to establish baseline information on waterfowl breeding and distribution density, so that future effects of acidification can be monitored. The Ranger Lake section (slightly south of the TLW) examines habitat parameters relating to reproductive success in waterfowl and the effects of acid precipitation on that success. Results indicate that headwater systems in Algoma are becoming acidified and this could have adverse effects on waterfowl reproduction.

Relationships between macroinvertebrate and fish faunas in small headwater lakes in the Ranger Lake area. Canadian Wildlife Service Ontario Region, LRTAP program. 48p, 2 append., October 1982.

Summary

Trophic relationships in 10 lakes in the Ranger Lake area (south of the TLW in Algoma) were examined to study the effects of acidification on the availability and abundance of waterfowl food. The focus is upon the relationships between macroinvertebrates and fish, and has implications for waterfowl reproductive success. The abundance and diversity of macroinvertebrates was higher in lakes without fish, thus as acid-sensitive fish disappear the selection of wetlands for breeding will change.
