When new survey data for a site is made available, one off the first things we might want to do is recalculate our pond volumes.  Sometimes the elevation of containment in the survey data isn't quite what its supposed to be (e.g. survey errors, construction of dam raise not complete at time of survey etc).

Commands used

• Surface water/Info/Find maximum containment elevation
• Structures/Pond/Create pond surface
• Structures/Dams/Draw a dam
• Grid/Merge/Merge dam into grid

Troubleshooting

Unable to create a pond at the target elevation, as the point selected was not in an enclosed basin (at the target pond elevation).

When creating a pond, if the above message comes up it means that water spills out of the basin at the target pond elevation.  Use the command Find maximum containment elevation to work out what the closure elevation is.
