Project: Identifies what part of the project a lake was sampled for.A core landscape position project lake = LPPA core LTER lakes sampled for biology as part of the landscape positon project = LTEROne of the lakes sampled as part of Ben Greenfield MS thesis (2000) = BenA landscape position project lake sampled only for fish = Fish.Lake_order: Lake order is a numerical surrogate for groundwater influx and hydrological position along a drainage network, with the highest number indicating the lake lowest in a watershed. We define lake order as follows: -3 indicates isolated seepage lakes, -2 indicates seepage lakes connected by intermittent streams, -1 indicates seepage lakes connected by a wetland, 0 indicates headwater drainage lakes, and 1 through 4 indicate drainage lakes, with the number indicating the order of the stream that exits the lake (Riera et al. 2000).Area: lake area in acres. Using Arcview coverages, identified in Ben Greenfield MS thesis (2000) as described belowDirect_catchment: area of surrounding catchment feeding directly into lake (square meters). For drainage lakes, delineated starting from the outlet of the immediate upstream lake.Total_catchment: area of surrounding catchment feeding into lake and all lakes upstream of given lake.Max_depth (ft): Using agency published records, listed in Ben Greenfield MS thesis (2000) as described belowPerimeter (m): Lake perimeter. Using Arcview coverages, identified in Ben Greenfield MS thesis (2000)Shoreline_devel: Shoreline development factor, defined in Cole s Limnology textWetlands_250m: Percent wetlands within catchment within buffer strip 250 meters distance from lake. Methods in Ben Greenfield MS thesis (2000Wetlands_500m: Percent wetlands within catchment within buffer strip 500 meters distance from lake. Methods in Ben Greenfield MS thesis (2000Mean_depth (ft): Mean depth, using WDNR data, when available.
