to the Main Street site, where a ladder had been lowered by rope.
|Using duct tape to attach a stencil to the wall. Two stencils were created, each five feet long|
one taped above the other. The material was FedEx boxes. Making the stencils took four hours.
|The paint use was Benjamin Marine D.M.T. Acrylic "Safety White,"|
suitable for use in places that will be wet or under water.
|About to paint the top markers and numbers. Nine feet was chosen because since record|
keeping began in 1942, no flood has exceeded nine feet, and only five have exceeded seven feet.
|Wall painted, stencils removed. Except in time of extreme drought|
the water is never low enough to paint a marker for one foot.
