Forestry Note: A HANDY GAUGE FOR FOREST AND FARM ROAD CONSTRUCTION MEASUREMENTS 1 of 4 This Forestry Note describes a simple, low-cost gauge for slope and height measurements to use when constructing dips, installing culverts and properly sloping road surfaces. Accurate measurements are needed when constructing a forest or farm road to insure good drainage and low maintenance costs, and to minimize soil erosion (Figure 1). Road Dips Dips are used for surface drainage of outsloped roads and for cross-drainage of crowned roads. On-site measurements of height and slope are needed in constructing dips (Figure 2). Figure 1. Forest road with good surface drainage Figure 2. Dip slope and height measurements Figure 3. Where dip height is too low, high water may flow over the berm and cause erosion Figure 4. The trough of the dip is eroding because the slope is too steep (over 3% average) Figure 5. The trough of the dip is filling in because of too little slope (less than 3% average)
