I have the following error in .riv file written by Flopy (a dot is placed between stage and conductance when conductance > 10E+6):

I would be glad to know if I am missing something there.

Thanks in advance!

Just out of curiousity, do you have the free format flag enabled in your bas package/for your model? My first thought is that it looks like the value's precision is completely filling a fixed width column. If the free format option is not enabled the width of floating points is 10 digits. To check and change from fixed format files to free format:

print(model.free_format_input)

# change to free format
model.free_format_input = True  

# change to fixed format
model.free_format_input = False

model.write_input()

Many thanks for the quick response! The free format option was not enabled. It worked after changing from fixed to free format.
