How
it works
A typical structure is formed by building
a dam across an existing gully or low lying area. Earth for the
dam is dug out above the dam with heavy machinery to form a bowl.
Generally the ponded area fills with water within a year. An overflow
pipe is installed through the dam to control the water level and allow
water to spill through the dam without causing erosion.
How it
helps
Prevents soil erosion and protects
water quality by collecting and storing runoff water.
Provides water for livestock,
fish and wildlife, and recreational opportunities.
Adds value and beauty to a
farm or farmstead.
Provides a water supply for
emergencies.
