Water Level History - Station Summary* 7. Lake Inlets 8. Additional Inlet Information USE 9. Lake Outlets 1. Additional Outlet Information 11. Water Control Structure (Dam) 12. Surrounding Watershed Characteristics, Shoreline Characteristics, and Riparian Landscape Observations² 13. Resorts And Campgrounds 1. Lake Access 2. Current Water Level 3.

Age Class Frequency Distributions 22. Status Of Fishery And Field Notes 23. Water Quality (Winter Observations) (added to revision 1/21/21) ONLY 24. Survey Attachments (added to revision 21522) ¹ Water Level History report: This data has not yet been migrated into the Fisheries LSM database. On 1/8/29, two additional Water Level History report components (Readings and Station Summary) were added. ² Effective 3/25/214, the Surrounding Watershed Characteristics, Shoreline Characteristics, and Riparian Landscape 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: 1. 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 after noon on /2/21 may not be reflected in the Distribution tables until /21/21. FOR OFFICE USE ONLY: As of revision 21522, this page is automatically suppressed on signed versions of this report (area supervisor, region manager, research biologist, research supervisor, program staff, or program manager signed). Fisheries Lake ID = 1134, Survey ID = Lake Survey Report revision: Data Date: /2/21 at 1:5 pm.
