Hello everyone, I’m having trouble getting reservoirs to work in SWAT+. I have set up 2 reservoirs, and I think I have defined all required files (hydrology, initial conditions, and decision tables), but the output file reservoir_mon.csv is complete

My questions

  1. Is there a known issue with SWAT+ rev61.0.1 (together with Editor v3.0.8) where initial.res / initial.wet are not read and reservoirs start with zero volume?

  2. If so, which combination of SWAT+ executable revision and Editor version do you recommend for projects that use reservoirs with decision tables and non-zero initial volume?

  3. Is there anything obviously wrong in the way I am linking reservoir.res, initial.res, hydrology.res, and the decision table that would explain why reservoir_mon.csv is all zeros?

Any guidance or example reservoir setup (with working reservoir_mon.csv) would be very helpful. I can share my .res files or screenshots if needed.

Thank you in advance,


reservoir.con
initial.res
reservoir.res
reservoir_mon.csv
res_rel.dtl
