Good day,

How can I treat missing flow data? Should I enter -99 for the gaps, or leave it blank? I don't have a donot catchment to perform interpolation.

I also have an issue with the date format for observed flow. The software misaligned my data. My flow data starts from 2021, but the software moved the data for 2021 to 2024, see screenshot. This just doesn't look right. I am not sure if the problem was my date format? I used Excel to prepare my observed data.
