*** After letting the dam sit for several hours, an evaluation of the dam's permeability will be taken and a possible addition of a liner will be added in order to increase the amount of water that is held back. The liner material would be draped on the upstream side of the dam, and more rocks would be placed up against it to hold the liner in place. Another possible problem is that the rock may sink into the creek bed. I have confirmed that Arden Hills will be able to dump another load of rock within one day if it is needed. This extra rock would be fitted on top of the sinking dam in order to keep the dam high enough to hold the water back. * * * The use of two or three shovels, as many wheelbarrows as are available, and a pair of work gloves for each helper, will be needed. The safety hazards that could arise could include: dropping rocks on hands and feet, blisters and scrapes on hands from working with the rocks for hours on end, possible muscle injuries from lifting heavy rocks and carting loads of rocks by wheelbarrow, and heat related problems like exhaustion and possible heatstroke. The delivery of the rocks will occur the day before work is started, so that no one will be hurt as they are unloaded. I will spend a couple of minutes with each day's work crew explaining and Demonstrating how to properly lift heavy objects, like rocks, and I will also demonstrate the correct load sizes to be carried in a wheelbarrow. Work gloves will be provided to help prevent basic wear and tear on the hands, and to help reduce rock -handling discomfort, which is usually why rocks are accidentally dropped on fingers and feet. A first aid kit will be on hand with Band-Aids for minor cuts and scraps and materials to take care of blisters. Also available will be lots of water and some `Gatorade' type drinks to reduce the risks of overheating and heat exhaustion. For this project, boy scouts from my troop and other troops, my family, family friends, neighbors, and possibly some volunteers from the Arden Hills Park and Recreation Department, will be involved in the planning and/or the physical working that will be involved in this project. The bulk of the project will take place on three days. Tuesday and Wednesday for the main work, Thursday for observations, and Friday to wrap the project up and mend any problems. Each of the three main days, my goal is to have eight to ten workers and 4work for approximately five hours.
