Our speakers are ardent and knowledgeable people who know hydrology and are passionate about the rugged terrain and wild waters of the Driftless area. The video starts with the basics - how groundwater works, interconnections to surface water, land use impacts and drinking water impairment. Jeff Broberg led us through this with humor and grace. Jeff's home in rural Winona doesn't have a safe water supply, so he has a personal stake in the water quality of the area.
Next our speakers addressed two examples of watersheds - one in Minnesota and one in Iowa. The WinLac watershed in Minnesota surrounds the cities of Winona and La Crescent, along the Mississippi. The uplands of this watershed are in the Karst bluffs and land use has heavily impacted drinking water quality. Paul Wotzka described the impacts we see in this small watershed, including the impacts of row crop and animal agriculture. When land use changes, water quality improves. How does that work? Paul explained how his land practices have improved the water at his home.
The second watershed we looked at is Bloody Run in northeastern Iowa - read more about Bloody Run at this link. Larry Stone is part of the Save Bloody Run movement, and he provided an update on where this case is in the courts and on the ground. The webinar wrapped up with a lively question and answer session led by LWV UMRR Chair Mary Ellen Miller.
Many thanks to our speakers for this excellent program!
