Exactly. That's the experience they've had in Minnesota and North Dakota. The water storage projects were chosen based on LiDAR surveys that were done for the entire Red River basin, from the Canadian border south. This has been a long-term project the U.S. Army Corps of Engineers assisted the state governments with over many years, and the LiDAR mapping allowed them to get the data on where the best places would be to store water. When they went to these landowners, I'm told, they were fairly cooperative with the idea, providing there was some compensation, because they could see they weren't really getting crop off those farms every year anyway.
