Shorelines should have 3:1 slopes to reduce the chance of aquatic vegetation problems. Slopes that are too steep (more than 2:1) can be a safety hazard for people and livestock and could slump or slide into the pond. Shaping of the banks during pond construction may cost extra but can save money in the long run by reducing aquatic vegetation problems. The dam should be protected from wave action and erosion. Rock riprap or special purpose grasses are commonly used on dams for wave protection.
