Caption: V-Flume
Additional Description: Genoa resident J.W. Haines is generally credited as the inventor of the V-shaped flume. Haines first built a log flume just south of Genoa in 1866, and patented the V-flume design on September 20, 1870. Prior to Haines’ design, log flumes were commonly u-shaped and prone to lumber jams and overflows, making them inefficient. Haines’ design solved the problem of jams and overflows; if lumber got caught in the V-flume, water would simply back up, elevate the wood, and release it to continue on.
