Morphology

impoundment = impound (semi-transparent) = impound + ment

This sense is a domain-specific extension where 'impoundment' refers to a body or structure that confines water (a reservoir), which is derivable from 'impound' but represents a specialized technical meaning.

Etymology

The word impoundment can also mean a place where water is held back by a dam, and it keeps the same idea: im- 'in' plus pound 'to keep', so water is 'kept in' one place. That's why a reservoir or an area behind a dam is called an impoundment.
