 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. ​Outlet flows for such multi-basin ​lakes are defined for each lake basin which has an outlet to the outside of the multi-basin lake. Flow between ​lakebasins ​are not defined in here. Maximum five outflows of a multi-basin lake is allowed. ​Smaller 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.g. depth). Flow between lakebasins of such 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]].
