Project Number: 9KB32
Project Chief: Dale M. Robertson
Project Topics: Water quality, meromictic
Cooperators: Jackson County
Period of Project: October 2002-September 2004
Water-quality profile in Wazee Lake demonstrating unique water quality below the thermocline.
Because Wazee Lake is only about 20 years old, it is undergoing the very early stages in its aging process. Some intermittent measurements of the lake’s water quality have been made in recent years and changes have been observed. One change is that the lake has gone from being dimictic, a lake with complete mixing during spring and fall, to being meromictic, or a lake with a monimolimnion (a lower zone which does not mix with the primary mass of lake water). A program of systematic water-quality monitoring is needed to document changes, to allow for early detection of undesirable changes, and to aid in making management decisions.
Because Wazee Lake is such a valuable and unique resource to Jackson County, the region, and the State of Wisconsin, the County wants to manage and develop the lake and surrounding park for public use in ways that avoid damaging the quality of the lake. The primary reason for the proposed monitoring of Wazee Lake is to build on the lake’s water-quality data base.
The goals of the proposed program are to (1) determine the current water quality and trophic status of the lake, (2) begin evaluating the impact of the beach area on the water quality of the lake, and (3) build a quantitative database so that improving or worsening changes or trends that might occur in the future can be detected quickly and evaluated objectively.
