bathymetry: CSLS bathymetry relationships
In WDNR-Water-Use/CSLSdata: WI DNR Central Sands Lakes Study Field Data

Description Usage Format Details References Examples

Info from bathymetry data in ArcGIS for the lake including the elevation (m), surface area (m^2), and volume (m^3) relationship. Calculated using the Storage Capacity tool in Spatial Analyst Supplemental Tools. Also includes:

The average lake profile (horizontal distance from highest shoreline for each contour level, m), calculated from the lake elevation rasters.
The area of each plant community at each elevation.
The area of suitably hard substrate for centrarchid fish species at Pleasant Lake

1	data(bathymetry)

A data frame with the following columns:

lake: name of lake, i.e. "Pleasant", "Long", "Plainfield"
elev_m: elevation of lake surface above mean sea level (m)
area_m2: surface area of lake when it is at this elevation (m^2)
vol_m3: total volume of the lake when it is at this elevation (m^3)
horiz_dist_m: horizontal distance of this lake shoreline from highest lake shoreline (that can be calculated in the raster file) (m)
plant_area_m2: total area of lake used to calculate plant areal extents (m^2)
upland_m2: area of upland plants at this lake at this elevation (m^2)
inland_beach_m2: area of inland_beach plants at this lake at this elevation (m^2)
emergent_m2: area of emergent plants at this lake at this elevation (m^2)
floating_m2: area of floating plants at this lake at this elevation (m^2)
submergent_weed_m2: area of submergent_weed (Potamogeton) plants at this lake at this elevation (m^2)
submergent_algae_m2: area of submergent_algae (Nitella) plants at this lake at this elevation (m^2)
submergent_m2: area of submergent plants at this lake at this elevation (m^2)
upland_pcnt: area of upland plants at this lake at this elevation (% of lake outline)
inland_beach_pcnt: area of inland_beach plants at this lake at this elevation (% of lake outline)
emergent_pcnt: area of emergent plants at this lake at this elevation (% of lake outline)
floating_pcnt: area of floating plants at this lake at this elevation (% of lake outline)
submergent_weed_pcnt: area of submergent_weed (Potamogeton) plants at this lake at this elevation (% of lake outline)
submergent_algae_pcnt: area of submergent_algae (Nitella) plants at this lake at this elevation (% of lake outline)
submergent_pcnt: area of submergent plants at this lake at this elevation (% of lake outline)
meanHrdAtNest: approximate area of suitably hard substrate for centrarchid fish at this elevation (% of lake outline)

Raw csv data is processed in the data-raw/ subdirectory of this project with the function import_bathymetry.R which is run by runall_cslsdata.R.

import_bathymetry.R loads bathymetry data from ArcGIS for all lakes including the elevation (m), surface area (m^2), and volume (m^3) relationship. No cleaning is needed. It then calculates the average lake profile from the lake rasters. Note that due to limitation in the raster extent, Long Lake calculations begin ~0.5 ft below maximum elevation available from ArcGIS elev/area/vol calculations. Next, it calculates the estimated area of each plant community at each elevation given rules on plant water depth limits (import_plant_limits.R). Lastly, it combines all of this with additional information on the mean hardness of substrate accessible to centrarchid fish species at this lake level (import_fish_substrate.R).
