Reservoirs can be added to a TIN in the Drainage module.

Creating Reservoirs

A set of triangles can be grouped together to create a reservoir. When creating reservoirs an outlet point must be specified for the triangles so that any flow path intersecting a triangle belonging to a reservoir can be routed directly to the outlet. The Node↔Outlet command is used to convert a stream node into an outlet point. Alternatively, use the Select Vertex tool to double-click on the vertex to bring up the Drainage Feature Point Type dialog where the vertex can be assigned as an outlet.

Deleting Reservoirs

An entire reservoir can be deleted by selecting the reservoir outlet using the Select Outlet tool to select the reservoir in the Hydrologic module. Then issuing the Delete | Selected Reservoir command in the tool's right-click menu.
