7 REPORT OVERVIEW - FOR OFFICE USE ONLY (This page is not part of the Standard Lake Survey Report and should be discarded ) Lake Name: Ocheda DOW Number: -4- Survey Type: Winter Kill Assessment Survey ID Date: //4 Survey Status: Field Work Complete The following (of ) report components are not included in this report:. Current Water Level. Benchmark And Gauge Descriptions / Locations. Water Level History¹ 4. Water Level History - Readings*. Water Level History - Station Summary* 6. Lake Inlets 7. Additional Inlet Information 8. Lake Outlets 9. Additional Outlet Information. Water Control Structure (Dam). Surrounding Watershed Characteristics, Shoreline Characteristics, and Riparian Landscape Observations². Resorts And Campgrounds. Fish Spawning Conditions 4. Erosion And Pollution. Fish Diseases And Parasites 6. Aquatic Vegetation And Shoalwater Substrates 7. Dissolved Oxygen And Temperature Profile Of Lake Water 8. Field Measusrements Of Water Quality 9. Laboratory Analysis Of Water Chemistry. Length At Capture With Last Incremental Length*. Back-Calculated Lengths. Age Class Frequency Distributions. Status Of Fishery And Field Notes 4. Other Species (added to revision /4/9). Water Quality (Winter Observations) (added to revision //) ¹ Water Level History report: This data has not yet been migrated into the Fisheries LSM database. On /8/9, two additional Water Level History report components (Readings and Station Summary) were added. ² Effective //4, the Surrounding Watershed Characteristics, Shoreline Characteristics, and Riparian Landscape Observations report component was modified to be included in the Standard 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.. Fish must have an "official" age assigned.. 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 //4 may not be reflected in the Distribution tables until //4. Fisheries Lake ID = 79, Survey ID = Standard Lake Survey Report revision: //4. Data Date: //4 at :4 pm.
