This data set includes bathymetric data for Fernan Lake, Idaho collected between October 2014 and August 2015 to construct a TIN (triangulated Irregular Network) to support limnological research, primarily a detailed annual water budget, and nutrient and sediment mass balances. Data were collected by Frank M. Wilhelm (faculty) and Trea LaCroix (MS graduate student) at the University of Idaho, Moscow Campus.

Files contained in this dataset include:
2015_09_01_650p95_TIN - the ERSI ArcGIS v10.2 triangulated irregular network 2015_09_01_Fernan_Lake_Bathymetry.cvs - a ASCII text file containing all depth data collected with the following fields (ID_NO - unique identification of each data point (1-22666); Sheet_ID - identification of datapoints from individuals sheets in the excel (xlsx) file; Description - description of the type of data point and collection method; Date - date on which data was collected in the field; Longitude - UTM longtitude NAD83 datum; Latitude - UTM latitude NAD 83 datum; Depth - depth in meters of each data point relative to lake surface on date of collection; ElevASL - elevation above sea level of each data point corrected for lake level on each date of collection). 2015_09_01_TIN_support_files (dir) 2014 10 11 Lake Depths sonar (dir) contains ArcGIS 10.2 files for lake depths collected on 11-Oct-2014 2015 07 01 Wetland Depths GPS and pole (dir) contains ArcGIS 10.2 files for wetland depths collected on 01-Jul-2015 2015 07 06 Wetland Depths interpolated (dir) contains ArcGIS 10.2 files for interpolated wetland depths 2015 07 16 Additional Bathymetry Lake Track (dir) contains ArcGIS 10.2 files of lake depths collected on 16-Jul-2015 2015 08 11 Additional bathymetry basin contains ArcGIS 10.2 files of lake depths collected on 8-Aug-2011 2015 09 01 650p95 Full Pool Polygon contains ArcGIS 10.2 files for polygon of lake at full pool at an elevation of 650.95 m above sea level 2015 09 01 650p95 Full Pool Pts contains ArcGIS 10.2 files of polygon vertices from polygon file at full pool elevation of 650.95 m above sea level 2015_09_01_Fernan_Lake_Bathymetry_data.xlsx (MS Excel 2013) file containing individual sheets of data collected on each date and metadata tab explaining each and collection methods.
