In 2005 Union Lake was sampled monthly from May through September, with the assistance from a Citizen Lake-Monitoring Program Volunteer. A summary of data from 2005 and available historical data follows. Secchi depth, Total Phosphorus (TP) and Chlorophyll-a (Chl-a) results for 2005 classified the Trophic Status of Union as Eutrophic. Many things can be done to better understand the lakes, as well as help improve them. Included in this report are recommendations and goals to assist with current and future concerns.
