-Outlet lakes in HYPE can cover a fraction of a sub-basin ​or the whole sub-basin. Large lake systems can be split into several ​sub-basins ​themselves ​(lake basins), which allows for different properties in different lake basins. ​Outlet flows for such lakes are then defined in an additional entry in //LakeData.txt//, see variable and column ''​LdType''​ in table belowSmaller lakes that are not divided into lakebasins ​may have two outlets ​defined in LakeData.txt (see [[start:​hype_model_description:​hype_routing#​outlet_lake_with_two_outlets|model description]]These outlets ​are defined ​by ''​ldtype''​ 5 and 6 for the main outlet ​and the branch outlet. For these lakes only the downstream subid of the branch need to be given in [[start:​hype_file_reference:​branchdata.txt|BranchData.txt]].+Outlet lakes in HYPE can cover a fraction of a subbasin ​or the whole subbasin. Large lake systems can be split into several ​subbasins ​themselves. Each such subbasin'​s olake is then a lake basins ​of the **multi-basin lake**. This allows for different properties in different lake basins ​(e.gdepth)Flow between ​lakebasins ​of such a multi-basin lake is not defined in LakeData (outflow parameters should be zero)Outflow parameters for a multi-basin lake are defined ​only for lake basin which has an outlet to the outside of the multi-basin lake. The main outlet ​leaves by the last lakebasin, while additional outlets leaves through branches ​of upstream lakebasinsMaximum five outflows of a multi-basin lake is allowed
  
 +Lakes that are not multi-basin lakes may have **two outlets** defined in LakeData.txt (see [[start:​hype_model_description:​hype_routing#​outlet_lake_with_two_outlets|model description]]). These outlets are defined by ''​ldtype''​ 5 and 6 for the main outlet and the branch outlet. For lakes with two outlets defined in //​LakeData.txt//​ only the downstream subid of the branch need to be given in [[start:​hype_file_reference:​branchdata.txt|BranchData.txt]].
