Landscape Position Project at North Temperate Lakes LTER: Lake Characteristics 1998 - 2000
Parameters characterizing the chemical limnology and spatial attributes of 47 lakes were surveyed as part of the Landscape Position Project. Lake characteristics compiled here include lake area and perimeter, catchment area, mean and maximum depth, shoreline development factor, elevation and percent wetlands within catchment area. Lake order was determined using a modification of the method of Riera et al. (2000). 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. Lake order for each lake was determined by field visit with presence/absence of streams confirmed, not base solely on topographic maps. Riera, Joan L., John J. Magnuson, Tim K.

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.
