Pipestem Dam (Kallberg Dam)

There is another dam on the Pipestem.  Early in the spring of 1935 when the new gravel pit was opened up in the Harold Kallberg pasture, the striplings were hauled into the creek right beside the gravel pit, and so the dam was made with no extra labor.  Since then Mr. Kallberg has made the dam higher and has hauled many loads of rock for rip‑rap work.  After the big rains fell, the water was backed up a distance to two and a half miles up to the high dam near Dover.  The lake proved a popular bathing place for visitors day and evening.
