| This file contains lake properties for **outlet lakes** with specific data available. Properties defined here override the properties and generic parameters given in [[start:hype_file_reference:geodata.txt|GeoData.txt]] and [[start:hype_file_reference:par.txt|par.txt]]. If you want to use a generic parameter from [[start:hype_file_reference:par.txt|par.txt]] for a particular lake in //LakeData.txt//, use -9999 as parameter value for that lake in //LakeData.txt//. Lake depth from [[start:hype_file_reference:geodata.txt|GeoData.txt]] may also be kept by using -9999 for the value in //LakeData.txt//. Lake properties include physical characteristics, e.g. depth, and outlet rating curve, regulation routine parameters, and parameters concerning nutrient cycling within the lake. In //LakeData.txt//, two regulation regimes can be defined; constant flow and seasonally varying sinus-wave shaped flow. For more regulation options, use [[start:hype_file_reference:damdata.txt|DamData.txt]], which extends the regulation options provided here. | This file contains lake properties for **outlet lakes** with specific data available.

| - | 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 (lake basins), which allows for different properties in different lake basins (e.g. depth). Flow between lakebasins of such a multi-basin lake is not defined in LakeData (regulation parameters should be zero). Regulation 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 lakebasins. Maximum 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 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.
