RESEARCH & MONITORING
Over the decades, numerous studies and projects have been completed by the Green Lake Association and other partners regarding Big Green Lake. These projects informed our practices to protect the water quality of Green Lake and its watershed. To gain a better understanding of this work, take a look below at our completed research studies, ongoing studies, and ongoing monitoring.

-
Lifelong Green Lake advocate Mary Jane Bumby prompted a century-long analysis of Green Lake's aquatic plant life, conducted by Dr. Bob Pillsbury of UW-Oshkosh. This report reveals how plant life has adapted to a hundred years of water quality shifts.
-
In 1921, a similar study was performed by H. W. Rickett, which Bumby later replicated for her 1971 Master's thesis at the University of Wisconsin-Milwaukee. Her passion for the lake's health led her to conduct similar research every decade from 1971 to 2001, and at 90, she financed the repeat of the original study in 2021.

ONGOING MONITORING
US GEOLOGICAL SURVEY (USGS) LAKE AND STREAM MONITORING
Big Green Lake is the deepest natural lake in Wisconsin. Changes in agriculture and urban development have altered the nutrient loading from the watershed and affected the water quality of the lake. Thanks to the Green Lake Sanitary District, this project is quantifying the amount of phosphorus and sediment delivered to Green Lake, measuring its water quality, and providing information about how the lake responds to input changes.
WATER ACTION VOLUNTEERS
The Water Action Volunteers Stream Monitoring Program (WAV) incorporates three levels of participation for citizen scientists who are interested in monitoring local streams: Introductory (Level 1), Status and Trends (Level 2), and Special Projects Monitoring (Level 3).
A primary objective of introductory monitoring is to increase public understanding of watersheds and how human uses of the land impact stream quality, while building a baseline of basic water quality information. Data collected help to identify acute issues in wadeable streams.
