Situated seven miles north of the mouth of the Fox River in the lower Green Bay is a little yellow buoy. This small but mighty buoy is equipped with a weather station that can be very beneficial for water recreation in the lower Green Bay area, and is also equipped with two water quality tools that have sensors to measure a suite of water quality parameters such as water temperature, pH, dissolved oxygen, and total algae. The buoy is powered by solar and communicates data to local websites for users to view. This buoy is appropriately named the Green Bay Entrance Light buoy, given its close proximity to the Entrance Lighthouse located in lower Green Bay.
NEW Water’s Aquatic Monitoring Program has been collecting water quality data in the Bay of Green Bay since 1986. For more information visit the Aquatic Monitoring Program page.
