Hi,
 
I hope you will be fine. I created streams and generate a subbasin of my river basin. I want to add shapefile of reservoir (which consist of total 3 reservoir and one of them reservoir has dam structure). when i add the shape file and select ok for watershed delineation process, the model are showing no reservoir and it will assume lake as a reservoir. The reservoir shape file and basin projections are same. How can we resolve this issue?
Please find the attached ss.

It is possible to make lakes reservoirs (and not ponds, which are
unmanaged) by including a RES attribute in the lake shapefile, and
setting its value to 1 for reservoirs. If there is no such attribute
the default is to act as if there was such an attribute and all lakes
have it set to 1. This does no harm: if no management data is supplied
in the SWAT+ editor the lakes will be treated as ponds. The message you
show is just an information message explaining this: there is no error.

I do not understand what you mean by the model showing no reservoirs:
can you explain.

Hi Chris,

Thanks for the explanation. I have successfully added the shapefile in QSWAT+ 3.0.3. and alos generated the hrus. Now, I need to add release data of reservoirs in model and also want to add inflow data of another river (i already selected the inlet point when i was created watershed). Where i have to add both data before run the model?
