1.0 INTRODUCTION A. BACKGROUND Kidder County is proposing a grade raise on CMC 2223, which is located 1.5 miles west and 0.5 miles north of Lake Williams, ND. The section of road currently intersects North Dakota State Highway 36 and crosses north end of Des Moines Lake. The grade raise is needed to prevent overtopping of the road by the rising Des Moines Lake due to large recent storm events. The section of road had an emergency grade raise done but may need to be raised further to ensure the roadway stays above the rising Des Moines Lake and provide erosion protection.

B. SCOPE OF WORK The purpose of this report is to summarize the hydrologic and hydraulic analysis of the drainage basin affecting CMC 2223. The outlet elevation of the basin is unknown so the hydrologic analysis is performed to determine the basins high water elevation. The hydrologic and hydraulic analysis are performed to size the culverts to ensure the runoff passes through the CMC 2223 stream crossing without overtopping the roadway.
Hydrologic Tasks: 1. Determine Des Moines Lake natural outlet elevation from lidar data; 2. Determine CMC 2223 stream crossing watershed boundary; 3. Determine 25-year peak runoff flow at CMC 2223 stream crossing;
Hydraulic Tasks:
1. Size proposed CMC 2223 culverts for 25-year peak runoff flow without overtopping the roadway.
Alternative analysis considered for the closed basins from Section lll-04.12 Grade Raises (Closed Basin) of the North Dakota Department of Transportation Design Manual.
Option 1 Grade Raise above the natural outlet elevation Option 2 Grade Raise above the 3-year net storage forecasted water
elevation Option 3 5’ Grade Raise above the existing water elevation
Note that all elevations stated in this report are based off North American Vertical Datum of 1988 (NAVD 88). 2.0 HYDROLOGY
A. DES MOINES LAKE OUTLET ELEVATION The existing Des Moines Lake outlet elevation was determined utilizing Watershed Modeling Software (WMS 11.0) to analyze lidar data from the North Dakota State Water Commission. From this data, an approximate outlet drainage path could be determined at different elevation contours. The Des Moines Lake approximate outlet drainage path and ultimate Des Moines Lake overtopping elevation of 1767.06’ are shown in Figure 2 below.

B. STREAM CROSSING WATERSHED AND 25-YEAR PEAK RUNOFF Utilizing USGS Streamstats Web Application for Solving Regional Regression Equations, a watershed and 25-year peak runoff flow were determined for the culvert crossing located within the proposed grade raise. The watershed and peak runoff flow are shown in Appendix A and summarized in Table 1 below. The total CMC 2223 stream crossing watershed is 37.29 square miles determined from digital elevation models in WMS 11.0 but only has a contributing watershed area of 20.17 square miles which was determined from USGS Streamstats Web Application for Solving Regional Regression Equations. The 20.17 square miles was a combination of two watersheds in Streamstats of 1.37 square miles and 18.8 square miles. The ruggedness of 43.8 ft/ft and the compactness ratio of 2.58 were obtained from the 18.8 square mile watershed and used to calculate the total discharged in the attached spreadsheet using the regional regression equations for peak-flow frequency estimate in North Dakota.

3.0 HYDRAULICS
A. ANALYSIS OF ALTERNATIVES As per the North Dakota Department of Transportation Design Manual Section III-04.12 Grade Raises (Closed Basin), all alternates shall be considered in this analysis. The typical sections for these options are attached in Appendix C. Option 1 is to raise the grade above the final outlet elevation for the basin. This option would involve raising the existing centerline subgrade elevation to 1769.47’. This is approximately a 4.91’ grade raise over the lowest elevation of the existing roadway. This option is the most expensive but ultimately the best long-term solution. Option 2 is to raise the grade to be higher than the elevation indicated by the forecasted three-year storage elevation. As no yearly water elevation data has been kept on Des Moines Lake, this option was not analyzed. Option 3 is to raise the grade up to 5’ in elevation from the existing water surface. This option would involve raising the existing centerline subgrade elevation to 1769.20’. This is approximately a 4.64’ grade raise over the lowest elevation of the existing roadway. This option would be a temporary solution and recommended as a more economical solution. B. CULVERT IMPROVEMENTS
The stream crossing is located 1,025 feet north of the intersection of ND State Highway 36 and CMC 2223. This crossing was analyzed with both the existing and proposed culverts and the HY-8 hydraulic analysis is attached in Appendix B. In checking the sizing, the tailwater for the basin was considered to be at elevation 1767.06’ and option 1 grade raise constructed. At the stream crossing, there is currently one 24” corrugated steel pipe (CSP) installed. The analysis indicated the existing culvert will handle the 2-year design discharge without overtopping the roadway. The analysis for the proposed crossing showed that installing one (1) 54” corrugated steel pipe (CSP) would handle the 25-year design discharge without overtopping the roadway. The headwater for the design discharge was 1768.65’ with an outlet velocity of 5.91 cubic feet per second (cfs). The roadway is overtopped just under the 100-year discharge.
