| Summary |
This guidance document provides guidance to dam owners on which devices, methods, or
systems may be used to lower the water level in a reservoir created by an impounding structure.
Drains and related devices allow lowering of the reservoir ahead of a major precipitation event,
during repair or maintenance of the dam, to relieve pressure on the dam as needed in response to
an inspection or evaluation by a professional engineer, or in response to other operational and
maintenance issues. |
