Table 1
Predictor data layers included in the national aquatic spatial dataset, where Processing Steps letter designations are A – PARC (Project-Aggregate-Resample-Clip) process to match the template, B- Summarized by Hydrologic Unit Code 12 (HUC12), C-Summarized by stream reach, D. All predictors were generated for both lakes and streams except mean annual stream flow and slope (stream only) and shore area ratio (lake only).
