lake_levels: CSLS daily lake levels
In WDNR-Water-Use/CSLSdata: WI DNR Central Sands Lakes Study Field Data

Description Usage Format Details Source See Also Examples

Daily lake level observations for the CSLS lakes. Lake gages are maintained by the United States Geological Survey. Raw data are retrieved from DNR Water Use section ArcGIS feature services for the Central Sands. Water quantity information is summarized at a daily time step for these measurements. The feature layer of interest is https://uadnrmaps.wi.gov/arcgis/rest/services/DG_HiCap/DG_CSLS_QUANT_MON_WTM_EXT/FeatureServer/2.

1	data(lake_levels)

A data frame with the following columns:

lake: associated lake (Pleasant, Long, Plainfield)
site_id: unique CSLS site id
date: date of measurement
level_m: lake elevation, meters above mean sea level
area_m2: lake area at this elevation, m^2
vol_m3: lake volume at this elevation, m^3

Raw csv data is processed in the data-raw/ subdirectory of this project with the functions import_water_levels.R and subset_lake_levels.R which are run by runall_cslsdata.R.

import_water_levels.R downloads the current feature layer from DNR feature services with water quantity measurements in the Central Sands (summarized at a daily time step). Feature layer of interest is DG_HiCap > DG_CSLS_QUANT_MON_WTM_EXT > Layer 2 (W13101.WU_CSLS_QUANT_DATA). The only cleaning performed is subsetting to desired parameters and adjusting datetime formats.

subset_lake_levels.R subsets larger water level data frame by USGS_id to retrieve only CSLS lake level records.
