MODELMUSE modlow6 LAK input

[dalegr...@gmail.com]

I have some difficulty in importing LAKE data to MODLOW6 in MODELMUSE. After I load the necessary data into the LAKE object MODFLOW features LAK page and press OK, the data seem to disappear from the model setup. Is there a workaround to import the data into MODELMUSE? Thanks.

I have the same problem with MODFLOW6 and Modelmuse 4.3.0.0: the checked LAK package disappear after pressing OK.

• Is this a bad configuration or a bug?
• Does somebody find a workaround?
• Is it the same with modflow 2005?

I can post a basic example if this can help

Thanks

The most likely reason for lake data not being saved is that no transient lake data was specified.

@ RichardBWinston : yes, you are true, LAK disappear if there is one missing data in Lake Time Properties.

I was able to check the LAK permanently 2 hours after my post but I performed a W10 update to 19041.867(french) in the mean time.

All my old test project with unchecheked LAK "bug" are now checked. This need to be confirm by somebody else because I am not sure of the my old programs status...

For information, my parameters are (with no failure):

Lake properties: Number of outlet:0, Horizontal&Vertical checked, Single-cell lake unchecked, -0.5, -5, 0, Kz, 0.1,0

Lake time properties: -1,0,Active,0,0,0,0,0,0

Lake table: nothing

The test project is a 10x10x1 cells 10m thickness and 2 left and right CHD lines at -1m and -5m

Problem solved for me

Thanks

Yes I have also faced the same problem and defining all the LakeTime Property have solved my issue.Thank you @ bepi...@gmail.com and @RichardBWinston

Hello,

I have a simular problem with modelmuse 5 and mf6:

An error message occurs if I define a lake and I can't define a lake.  Is the reason that I build a steady state model with no transient lake data?

Thanks.

There is a bug in ModelMuse regarding lakes in MODFLOW 6. Please contact me at my work email, rbw...@usgs.gov,  for a fixed version.
