The sediment basin from Problem 6 (attached) will include both a conventional riser-type principal spillway and a separate emergency spillway. Using the attached elevation vs. storage rating curve for the proposed sediment basin, establish the following elevations to the nearest 0.1 ft:


  1. Principal spillway crest
  2. Permanant pool level



Note: either show ruler drawn coordinate lines of these two points on the chart or show linear interpolations from the table
