REPORT OVERVIEW - FOR OFFICE USE ONLY (This page is not part of the Lake Survey Report and should be discarded ) Lake Name: Loon DOW Number: 32-2- Survey Type: Standard Survey Survey ID Date: 6/27/26 Survey Status: Field Work Complete The following 9 (of 32) report OFFICE components are not included in this Lake Survey Report: 6. Water Control Structure (Dam) 7. Surrounding Watershed Characteristics, Shoreline Characteristics, and Riparian Landscape Observations² 8. Resorts And Campgrounds USE 9. Fish Spawning Conditions. Erosion And Pollution. Fish Diseases And Parasites 2. Aquatic Vegetation And Shoalwater Substrates 3. Laboratory Analysis Of Water Chemistry. Water Level History¹ 2. Lake Inlets 3. Additional Inlet Information. Lake Outlets. Additional Outlet Information. Length At Capture With Last Incremental Length*. Back-Calculated Lengths 6. Age Class Frequency Distributions 7. Status Of Fishery And Field Notes 8. Water Quality (Winter Observations) (added to revision /2/2) 9. Survey Attachments (added to revision 2622) ONLY ² Effective 3/2/2, the Surrounding Watershed Characteristics, Shoreline Characteristics, and Riparian Landscape ¹ Water Level History report: This data has not yet been migrated into the Fisheries LSM database. On /8/29, two additional Water Level History report components (Readings and Station Summary) were added. Observations report component was modified to be included in the Lake Survey report if it did not include any Watershed and Shoreline characteristics and only consisted of Riparian Landscape Observations. * Length At Capture With Last Incremental Length report: The following criteria must be met for a report to be generated:. The fish species must have an assigned body scale constant. 2. Fish must have an "official" age assigned. 3. Fish must have a digitized measurement marked for back calculation use. Note: The data source for Length and Age Class Frequency Distribution tables is updated twice daily - once at noon and once overnight. Any changes to the data made before noon on 7//26 may not be reflected in the Distribution tables until after 2:3 pm on 7//26.
