The objective of a three-year project (2019 to 2021) was to collect new general water quality data for Little Traverse Lake and merge these with historical data into a database. The combined data are used to ascertain the present-day status of the Lake, identify possible problems, and examine long-term trends and changes.
Algal nutrients (total phosphorus and nitrate), chlorophyll, Secchi Depth, dissolved oxygen, and other parameters were measured at several depths in the off-shore waters. Mixed species of periphyton and Cladophora were measured at nine near-shore sites.
The data from this sampling program and abundant historical data dating back as far as 1990 have been entered into a this EXCEL database. The database contains over 15,000 measurements of various water quality parameters.
PCs with Excel. The database graphing functions will not run using other programs (eg. Google Docs) or on Macs.
