Preface
Lake Erie has experienced several decades of accelerated
eutrophication and toxic substances contamination. During the latter
part of the 1960s remedial actions were planned and by the latter
part of the 1970s, many of the plans were at least partially
implemented. The first signs of lake recovery are now being observed
through comprehensive monitoring programs. The intent of this report
is to highlight the findings and conclusions of the 1978-1979 Lake
Erie Intensive Study by placing them in perspective with earlier
investigations and subsequent monitoring data from 1980 to 1982,
where available. The primary purpose of this report is to provide
management information in the form of a review of the lake's status
and its trends - and in the form of recommendations to ensure
continued improvements in the quality of its waters and biota. For
more detailed discussions of the methods, quality assurance
procedures, and results of the study, the reader is referred to the
final project report of the Lake Erie Technical Team, "Lake Erie
Intensive Study 1978-1979 - Final Report," edited by David E.
Rathke.
Abstract
This report is to highlight the findings and conclusions of the
1978-1979 Lake Erie Intensive Study by placing them in perspective
with earlier investigations and subsequent monitoring data from 1980
to 1982, where available . The primary purpose of this report is to
provide management information in the form of a review of the lake'
s status and its trends and in the form of recommendations to ensure
continued improvements in the quality of its waters and biota. Lake
Erie has experienced several decades of accelerated eutrophication
and toxic substances contamination. During the latter part of the
1960s remedial actions were planned and by the latter part of the
1970s, many of the plans were at least partially implemented.
