Large Scale Lake Planning
This document will cover the years 2014-2020. The plan includes data about the plant community, watershed and water quality of the lake. There is no known historical aquatic plant data for Tarrant Lake.
The Columbia County LWCD will inventory the aquatic plant community in Tarrant Lake, Columbia County, and write an aquatic plant management plan following DNR guidance. This process will provide education to the community while inviting their input. A bathymetric map will be created to document lake depths, which have changed due to the recent dredging project. They will also use data already collected to do a water chemistry load analysis and model phosphorus. In addition, in order to provide an Aquatic Plant Management Plan that is complex in scope Columbia County will conduct a shore land health study with GPS photography on the land from the high water mark to the first 30\2019 surrounding the lake. All these efforts will be used to update the comprehensive lake management plan. There will be public meetings, and results will be compiled into a final report which will be posted on the County LWCD website.
