This is one of the most interesting features of the park, the lake spillway. Normally there is always water flowing over the top of the spillway, but as you can see, the low levels have left it high and dry. Also note how stagnant the water in this area has become.
These stairs follow the spillways path down a short ways to let you see its construction.
Probably rather impressive when water is actually flowing.

During the construction and early operation of the park, many tasks were accomplished by use of waterwheels. The original was actually a ways off in the forest on a natural flowing stream. This one (with the wheel from the original) was built later below the lake, allowing lakewater to fall and power it. This turned wheels and shafts inside the adjacent building that could be used for various jobs. When electricity was brought to the park in 1941 the waterwheel became obsolete. Another tool used early in the park was the hydraulic ram pump, which worked by suddenly stopping falling water and forcing it up a vertical pipe. A one way valve in the pipe would open and shut allowing water to go up the pipe but not down, doing this process up to sixty times a minute. The design of this pump allowed it to send water to a much higher elevation.
