Water Bank Program (WBP)

A program to set aside wetlands for a period of 10 years (renewable) for conservation purposes. Participants receive annual rental payments. As these contracts expire, participants are offered the opportunity to place the land in the Wetland Reserve Program.

Water Budget

An accounting of the inflow to, outflow from, and storage changes of water within a system, such as a watershed or aquifer

Water conservation

Practices that promote the efficient use of water, such as minimizing losses, reducing wasteful use, and protecting availability for future use.

Water content of snow

See Water equivalent of snow

Water crop

See Water yield

Water Demand

The amount of water that is required for domestic, municipal, commercial, agricultural, industrial, mining, power generation, waste dilution, navigation, recreation, and environmental (e.g., fish and wildlife) purposes.

Water equivalent of snow

Amount of water that would be obtained if the snow should be completely melted. Water content may be merely the amount of liquid water in the snow at the time of observation.

Water loss

While water cannot really be lost from the hydrologic cycle, water can be lost to the purposes of immediate use, by transformation (e.g., evapotranspiration), by leakage (conveyance loss), and by incorporation into other products and crops (consumptive use).

Water Quality Incentives Program

This program was authorized in the FACT Act of 1990 and is administered by the Farm Service Agency. It was repealed and replaced by the Environmental Quality Incentives Program in the FAIR Act of 1996. It provided cost-share assistance to implement comprehensive water quality protection plans and was funded by earmarking a portion of the Agricultural Conservation Program.

Water Quality Initiative

A multi-agency effort, initiated by USDA in 1990, to determine relationships between agricultural activities and water quality, and develop and implement strategies that protect surface and groundwater quality. This program, which builds on earlier USDA water quality protection efforts, includes research activities, projects involving landowners, and information and data development. Landowners participate in demonstration projects, hydrologic unit area projects, water quality special projects, and water quality incentive projects.
