**Do you know how to calculate Dam Water Capacity in Real Time?**

**1 liter of water = 1000milli liter water**

**1 cusecs =?**

*Cusec is a measure of flow rate and is informal shorthand for "cubic feet per second"(28.317 litres per second).*

**1 cusec = Flowing or Running 28.37 litre – per second.**

**1 cusec = 1 கன அடி**

**How do I calculate 1 TMC water?**

**TMC refers to “Thousand Million Cubic Feet”.**

**Generally,**

**1 Cubic Feet = 1ft x 1ft x 1ft = 0.3048 m x 0.3048 m x 0.3048 m = 0.02831684 m^3.**

**Since, 1 m^3 = 1000 litres.**

**Therefore, 0.0283164 m^3 = 0.0283164 x 1000 = 28.3164 litres.**

**Also, Thousand = 1000 = 10^3**

**And, Million = 1000000 = 10^6**

**Therefore,**

**1 TMC = 10^3 x 10^6 x 28.3164 = 28.3164 x 10^9 litres of Water.**

**I cubic feet of water corresponds to 28 litres approximately.**

**1 thousand million means 1 billion**

**Hence 1 TMC corresponds to 28 billion litres of water**

**How To Calculate Dam Water Storage Capacity ?**

- Land managers need to know how much water is stored in their dams to manage water supply for livestock, spraying and other uses.

- The critical supply period is over summer and autumn when evaporation is high, and demand from livestock, irrigation or household use increases.

- Knowledge of your dam(s) storage capacity is also required if you plan to develop or expand an existing or new enterprise on the property. This page provides the steps needed to accurately calculate dam capacity and water volume in small farm dams (excavated tanks).

**Measuring the dimensions of your dam**

- 20–30m of surveyor tape (depending on the size of the dam)

- lightweight rope — long enough to reach from one side of the dam to the other

- binoculars

- an assistant

- notebook and pencil.
