 The Sinagua people, and possibly earlier cultures, intensively farmed the land surrounding the Well using its constant outflow as a reliable source of irrigation.Beginning about 700 CE, the Well's natural drainage into the immediately adjacent Wet Beaver Creek was diverted into a man-made canal running parallel to the creek, segments of which still conduct the outflow today.The prehistoric canal, estimated at nearly seven miles in length, likely drained into a network of smaller lateral canals downstream, supplying perhaps as much as 60 acres of farmland with water.
