Special Environmental Concerns: Ponds

 

Two types of ponds that 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 can include ponds located in golf courses or subdivisions.
 
  1.

Plan ahead by developing and using a comprehensive land use management plan that includes best management practices for ponds. Ponds can develop water quality problems that include algae, scum, stagnation, mosquitoes, and odor.

  2.

Determine the water source and water rights required for proposed ponds.

  3.

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).
  4.

Use best management practices to help maximize the protection of 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.
  5.

Ponds can provide habitat for many animal species and insects. Contact Idaho Fish and Game and the Public Health District for recommendations.
