Watershed management and water yield

Water conservation practices are described that produce more and better quality and quantity of water from rainfall and snowmelt. Studies that result in greater contribution of water from an area for a given set of soil conditions, geologic conditions, vegetative characteristics and climate. Vegetation densities are studied for balancing water yield from medium altitude zones of brush land where 25 years of records are available. Plot studies proved inadequate and as a result pairs of small watersheds were substituted that proved to produce more responsive data. A tabulation is included showing values and types of vegetative cover, soils and treatment applied. Data are also shown in graphical diagrams.
