So far I have used 300-400 tons of rip rap rock with the same remaining to do approx 800' of east shoreline and one of the 2 islands perimeters in view from the house. I am using both limestone and river rock of various sizes. The limestone is more flat and therefore is better in my project to remain on the steep sides of my gravel pit. The river rock tends to continue down into the water beyond the point I want it to go. Food for thought....if you are using riprap rock to help beautify your project you may want to create some curving dry river beds leading down into the water from the uplands. This is a great focal point and a nice place to plant a few shrubs and periennials. However, this is a great deal of work and not intended for all. I have been at this for over a year and hopefully will be done by the fall?
