Father Caspar Rehrl, the earliest founder of the Congregation, once said, "Oh, how I wish that the Sisters of St. Agnes might someday live on this beautiful land watered by springs." When Father Rehrl first passed through the ledge east of Fond du Lac in the 1850s, he found seven freshwater springs tumbling down its expanse. Those springs quenched his thirst. Through careful protection and management, three springs still traverse from east to west on CSA property and run to nearby Lake Winnebago, though their water is no longer safe to drink.
