Watering Facility POLLUTANTS ADDRESSED: Nutrients and Organics, Pathogens, Sediments

DESCRIPTION: This is a watering facility that is a solar powered well pump; it supplies water to livestock in remote location where electrical power is not available. This facility is cost effective and self supporting. LOAD REDUCTION MECHANISM:

Nutrients/Organics Management- Reduces animal wastes in streams by providing alternate source of drinking water. Pathogens- Reduces animal wastes in streams by providing alternate source of drinking water. Sediment Reduction – Reduces livestock trampling along stream banks.

LAND USE CLASSIFICATION: Grazing lands

ADDITIONAL BENEFITS: Better control over livestock movement Better control over livestock drinking water quality POTENTIAL TREATMENT AREAS: Grazing lands ALTERNATIVE MANAGEMENT MEASURES: Cross-Vane Weir Diversion Fencing Grazing Management PERMITTING REQUIREMENTS: Well will require a permit from ADWR.

LOW MEDIUM HIGH PLANNING AND IMPLEMENTATION:

1. The purpose of a watering facility is to provide adequate water for livestock and/or wildlife while minimizing impacts to streambanks and other areas that produce sediments.

2. Water facilities should be located to minimize

trail erosion and maximize forage.

3. Topography should be evaluated to minimize trail erosion and flooding erosion from tank overflow.

4. Watering facilities should be accessible to small

animals. Escape ramps for birds and small animals should be installed.

5. Adequate protection for livestock from wind and

snow/ rain during the winter and sun/heat during the summer should be considered.

6. The facility should allow for ice expansion

without damage.

7. The facility should require the minimum maintenance possible.
