Hi,
Attached is a Smath file showing how a first estimate is made of the hydro power potential from stream flow data.
This is based on the "Example 6.11 - E.M. Wilson - Engineering Hydrology - Fourth Edition - Solutions to Problems" published as a solution manual to the text book by the same author.

Look within!... The secret is inside you.
