error in volume reservoir

[Laura]

I have a problem in the reservoir.

The volume are less than the Volume of principal spillway (1000000m3)
and is allways 141400 m3...
The Flow In is similar to Flow Out.

I have an error when start run: error(74) floating underflow...

I don´t find the problem..
thank you!

Reservoir volumes are given in ha-m in SWAT, if I recall.  You are giving values in m^3 if that makes a difference.  If you're getting an underflow error, you probably can't trust the results of the run.  You'll need to figure out what is causing the problem.  Find out which module (the first *.f file in the output in the DOS window) the error is occurring in and then you might be able to figure out if some of your input data are incorrect.
