Questions to ask include: '''Access:''' Is the gate easy to access in all conditions? If not, consider a new configuration with ready access. </br> '''Operation:''' Does the gate operate smoothly or bind? If it binds, careful examination of the entire system is in order. </br> '''Debris:''' Does the dam have a history o...")
