It was around the same time that Broberg began to get involved with the Minnesota Trout Association and advocate for cleaner water to protect fish.

He began traveling around the state, actively learning more about Minnesota’s waterways and the projects to improve the state’s water quality. He was appointed to the LCCMR in the 2010s and at one point chaired the commission.

After he left the commission, he advocated for tighter control of Legacy funding. In March, he told the Minnesota Star Tribune he was concerned lawmakers were creeping closer toward interfering with the commission’s independent authority to allocate clean-water funding, calling it “usurpation through what I term legislative mischief.”

“Why not go to the governor and say, … You talk conservation, we want to see you walk the talk.”

After he retired, Broberg became an ardent groundwater advocate. He founded the Minnesota Well Owners Organization (MNWOO) and received a master’s degree in nonprofit administration from Saint Mary’s University.
