Dear WRF-Hydro User Group,

I am seeing unexpected behavior in LAKEOUT_DOMAIN2 during a gridded-routing simulation.

The lake water surface elevation remains constant (water_sfc_elev = 1797.731201) throughout the simulation, even though inflow changes substantially. The outflow also remains constant (3.813972), and the stage range is 0.0.

So, the lake stage does not respond to changing inflow.

Has anyone encountered this issue before? I would appreciate suggestions on what to check in the lake setup or parameter files.
