4.3.2 Watershed Development Works:
Watershed development works is to be done during implementation phase of watershed. Treatments begin from the highest point of the watershed and
move progressively downwards (ridge to valley), starting with the smallest stream and culminating in the main river of the watershed. Work is
location-specific, varying according to slope and geology as also the size of the stream being treated. The aim is to weave interventions into the contours of
nature, not to seek mastery over it. A net budget of 50 percent is allotted for this work.
.
Ridge Area Treatment Plans
In a watershed, the slopes falling from the ridge to the beginning of the plains are called ridge area. It is very important to treat the higher reaches of
the ridge has this is where the major water resources originate. This involves mainly highly and forest region in the watershed. Various watershed
managing structures should be build to arrest the erosion and degradation of forest with grasses in upper ridges.
