The Point View Resort on the Niangua Arm just installed what they believe is the largest fish habitat installation at a single location ever. Dozens of giant structures went in at the docks around the resort on December 1, 2018. Many of them are 15 feet in height. Some of the structures are simply colossal in size. Fishing for crappie (and even a few white bass) is reported to be outstanding around the new artificial fish habitat.
