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. 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.g. depth). 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 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 lakes with several outputs defined in //LakeData.txt// 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.
