Known at Malabar as Niman Spring, this spring was familiar to Indians for centuries, was frequently visited by Johnny Appleseed, and continued to draw deer to drink from the pond at nightfall. It emerges from deep underlying Silurian sandstone in a small cavern in the hillside and supplies water for the old spring house, a residence, two stock tanks, the market stand, a watercress bed, a barn, three hoglots, and the pond from which the gardens are irrigated. The nearby residence was built in 1820 as a combination residence and stage coach tavern after fear of the Indians had been broken forever at the Battle of Fallen Timbers, and the spring determined its location on the outskirts of Newville, then the county's most important settlement. Newville later disappeared with the construction of Pleasant Hill Dam. Pleasant Valley Road had once been an Indian trail leading from the Ohio River to Lake Erie and later became an important route for transporting wheat to ship and railroad. The spring has a capacity of 2,000 gallons per hour, with a 3° change all year.
