Water budget for pond
Water budget for pond may be expressed as follows.
Inflows = Out flows +storage.

Inflows include

• Precipitation falling directly in the pond.
• Run off from water shed.
• Seepage from the bottom and sides of the pond
• Regulated in-flow of water through water control device from source like, steams, rivers etc.

Out flow

• Evaporation and transpiration
• Seepage from bottom and sides of the ponds.
• Over flow from the ponds
• Intentional discharge through water control device
• Consumptive use for live stock.
