Idaho Environmental Guide for Local Governments: Ponds
Two types of ponds local governments should be aware of include 1) gravel pit ponds, which have a high potential of affecting ground water quality because water can move rapidly through gravel and sand and thus carry pollutants to ground water, and 2) aesthetic water use ponds, which include ponds located in golf courses or subdivisions.
- Develop and use a comprehensive land use management plan that includes best management practices for ponds. Ponds can develop water quality problems such as algae, scum, stagnation, mosquitoes, and odor.
- Determine the water source and water rights required for proposed ponds.
- Ensure ponds are properly constructed. Pesticides and other contaminants can enter surface water through runoff, soil erosion, spray drift, misapplication, or spillage and infiltrate to ground water through the soil. DEQ encourages ponds to be constructed and maintained to comply with the Ground Water Quality Rule (IDAPA 58.01.11).
- Use best management practices to protect human health and the environment. Best management practices for ponds may include aeration, buffer strips, pesticide and fertilizer regulation, pond liners, or ground water monitoring.
- Ponds can provide habitat for many animal species and insects. Contact Idaho Fish and Game and the Public Health District for recommendations.
