  \item When using the mover transport (MVT) package with UZF and UZT, rejected infiltration was paired with the calculated concentration of the UZF object rather than the user-specified concentration assigned to the infiltration. This bug was fixed by instead pairing the rejected infiltration transferred by the MVR and MVT packages with the user-specified concentration assigned in UZTSETTING with the keyword ``INFILTRATION.'' With this change, MODFLOW 6 simulations that use UZF with the ``SIMULATE\_GWSEEP'' option will not transfer this particular source of water with the correct concentration. Instead, the DRN package should be used to simulate groundwater discharge to land surface. By simulating groundwater discharge to land surface with the DRN package and rejected infiltration with the UZF package, the correct concentrations will be assigned to the water transferred by the MVR package.
  \item The SIMULATE\_GWSEEP variable in the UZF package OPTIONS block will eventually be deprecated. The same functionality may be achieved using an option available within the DRN package called AUXDEPTHNAME. The details of the drainage option are given in the supplemental technical information document (mf6suptechinfo) provided with the release. Deprecation of the SIMULATE\_GWSEEP option is motivated by the potential for errors noted above.
  \item The Streamflow Routing package would not calculate groundwater discharge to a reach in cases where the groundwater head is above the top of the reach and the inflow to the reach from upstream reaches, specified inflows, rainfall, and runoff is zero. This bug has been fixed by eliminating the requirement that the conductance calculated based on the initial calculated stage is greater than zero in order to solve for groundwater . Instead, .As a result, differences in groundwater and surface-water exchange and groundwater heads in existing models may occur. 
+ \item The capability to inactivate lakes (using the STATUS INACTIVE setting) did not work properly for the GWF Lake Package. The Lake Package was fixed so that inactive lakes have a zero flow value with connected GWF model cells and that the lake stage is assigned the inactive value (1.E30). The listing, budget, and observation files were modifed to accurately report inactive lakes.
