- Sediment

- Bank Erosion

- Low Dissolved Oxygen

- Loss of Riparian Vegetation and Aquatic Habitat

- Animal Feeding Operations

- Impacts from Drain Tiles


In recent years, water quality improvements along the Lower Bear River have focused primarily on the proper utilization of manure produced in animal operations. Manure is often applied to agricultural land to add nutrients and improve the quality of the soil without the added expense of synthetic fertilizers. Manure must be applied at the appropriate agronomic rate and under appropriate conditions. This is done to avoid excess nutrients inadvertently running off into nearby water bodies, which can cause over-fertilization of the water and result in algal blooms, fish kills, and other water quality problems.

Typically, waste storage facilities are constructed to store manure in a way that protects nearby water bodies and groundwater until it can be properly applied to the soil. Waste storage facilities can be constructed by excavating a pit or by building berms. Many storage facilities are lined to prevent leaching into the groundwater. Waste storage facilities are an integral part of a producer’s nutrient management plan and are essential in protecting agricultural land and water resources.
