The dam actually doesn’t control the level of the lake in high water,” explained Jansen. “The operator’s goal is to match the outflow of Rainy Lake with the outflow of the dam.
International Falls recorded 7.61 inches of precipitation, shattering the previous record of 4.53 inches that was set in 1925.Īs the northern quarter of Minnesota received 100-200% above the normal for April precipitation, the flow of Rainy Lake became difficult to control. For the Rainy-Namakan basin, this was the wettest April on record. March went out like a lamb, making way for a historic April. “So we asked the operators of the dams to target what we call the middle of the rule curve, and that resulted in reducing the lake level about four inches through March.” “We always want to play things on the safe side,” explained Jansen. Although the high flood risk rule curve was not implemented, the lake level was lowered at the time. “We decided not to implement that curve this year because the basin was experiencing normal conditions at the time and we were still in a severe drought following last year’s exceptional drought.”Ī rule curve is an optimal range to aim for when controlling the water level. “If it were to be fully implemented, it could result in reducing the level of the lake by about 12 inches,” said IRLWWB U.S. Every year by March 10, the Water Levels Committee of the International Joint Commission’s International Rainy-Lake of the Woods Watershed Board decides whether or not to implement a high flood risk curve when controlling the Rainy Lake Dam. Not everyone agreed with the concerns of Watson, Waller, and other Rainy River Basin residents. And obviously it went and it got way worse than I’ve ever seen.” “I didn’t dream that it would be this high or it would be this extreme, but with the amount of snowpack and frozen ground and in the spring rain, I had my fears way back in March. “Just being 75 years old and being around all those years, I sort of had this inclination that we were going to have a problem this spring,” said Watson.
