Multiple drainage areas outlet to lake.
Multiple drainage areas outlet to lake.
(OP)
I have 3 drainage areas that outlet to a lake at 3 separate points. How do I model the lake runoff? There is a dam outlet structure at the end of the lake.
Thanks,
Thanks,

This would be different for a river channel with a sloped water surface. But a pond routing assumes a level water surface, so the specific point of entry is not considered.
In most cases, the travel time through the reservoir will be very small in comparison to the other flow segments. You can verify this by setting up an additional flow segment (in the subcatchment Tc screen) using the Lake/Reservoir option.

If in doubt, try it, compare the results, and draw your own conclusions.
