(< 30 minutes, 30 minutes - 1 hour, 1 - 2 hours, More than 2 hours) [ ] Maximum depth of ponding observed (in inches) [ ] Describe the location(s) of observed ponding. Be specific (e.g., low spots in field, near tile outlet). [ ] Is ponding excessive, causing potential crop stress or damage? (No, Yes, slight, Yes, moderate, Yes, severe) [ ] What factors contribute to observed ponding (select all that apply)? (Clogged Drain, Flat Terrain, Soil Type (Clayey), Heavy Rainfall, Poor Design, Other (Specify in LONG_TEXT)) [ ] If 'Other' selected in previous question, please describe. --- DRAINAGE OUTLET FUNCTIONALITY --- [ ] Outlet Type? (Culvert, Open Ditch, Underground Pipe, Surface Drain, Other) [ ] Outlet Flow Rate (L/s or GPM) [ ] Outlet Blockage? (No, Minor, Moderate, Severe) [ ] Describe any observed outlet issues: [ ] Water Level at Outlet (m or ft) [ ] Evidence of Backflow? (Yes, No, Uncertain) [ ] Attach Photo of Outlet --- CHANNEL & PIPE CONDITION --- [ ] Pipe Diameter (inches) [ ] Pipe Material (PVC, Concrete, Corrugated Metal, HDPE, Other) [ ] Channel Slope (percent) [ ] Pipe Condition - Visible Damage? (No, Minor (Surface cracks, minor deformation), Moderate (Significant cracks, partial collapse), Severe (Complete collapse)) [ ] Describe any observed pipe or channel degradation (rust, cracks, settlement, etc.) [ ] Estimate Sediment Build-up in Channel (inches) [ ] Upload Photo of Channel/Pipe Condition --- SEDIMENT & OBSTRUCTION ASSESSMENT --- [ ] Average Sediment Depth (cm) [ ] Types of Debris Observed (Leaves, Sticks/Branches, Soil/Mud, Organic Matter (e.g., crop residue), Trash/Plastic, Other (Specify in LONG_TEXT)) [ ] Description of 'Other' Debris (if selected) [ ] Estimated Percentage of Drainage System Blocked by Sediment/Debris (%) [ ] Severity of Obstruction (Minor (Less than 10% reduction in flow), Moderate (10-30% reduction in flow), Severe (Greater than 30% reduction in flow)) [ ] Photo of Sediment/Debris Buildup [ ] Detailed Description of Obstruction Location and Nature --- VEGETATION MANAGEMENT --- [ ] Dominant Vegetation Types Observed (Check all that apply) (Grasses, Weeds (Identify Species), Shrubs, Trees, Algae, Other (Specify)) [ ] Detailed Description of Vegetation Presence & Location [ ] Estimated Vegetation Coverage (%) [ ] Vegetation Impact on Drainage (Choose One) (No Observable Impact, Minor Obstruction, Moderate Obstruction, Severe Obstruction) [ ] Describe Specific Areas of Concern Related to Vegetation [ ] Photos of Vegetation and Potential Obstructions [ ] Last Vegetation Management Date --- EROSION CONTROL MEASURES --- [ ] Riprap Condition (Excellent - Stable and Intact, Good - Minor displacement, still functional, Fair - Noticeable displacement, some loss of material, Poor - Significant loss, ineffective protection) [ ] Check Dam Height (feet) [ ] Terrace Stability (if applicable) (Stable, Minor erosion, Moderate erosion, Severe erosion) [ ] Describe Any Erosion Concerns [ ] Vegetation Cover Near Erosion Controls (Excellent - Dense and Well-Established, Good - Adequate coverage, Fair - Sparse coverage, some bare spots, Poor - Minimal coverage, significant erosion risk) [ ] Distance to Nearest Waterbody (feet) [ ] Attach Photos of Erosion Controls --- WATER QUALITY & RUNOFF ANALYSIS (OPTIONAL) --- [ ] Describe any unusual observations regarding runoff color, odor, or appearance. [ ] pH of runoff sample (if collected). [ ] Turbidity of runoff sample (NTU - Nephelometric Turbidity Units, if collected). [ ] Soil erosion observed in runoff? (Visual estimation) (None, Slight, Moderate, Severe) [ ] Potential pollutants detected in runoff (check all that apply): (Fertilizers, Pesticides, Sediment, Organic Matter, Other (Specify in LONG_TEXT)) [ ] Attach any photos/videos of runoff or surrounding area.
