Specifications include, but are not limited to: The consultant will conduct a drainage analysis and hydrologic assessment of the Reservoir Brookwater shed, which will include an assessment of the hydrologic capacity of the railroad culverts connecting Monkey Pond to Lake Waukewan. NHDES, under the NH Stream Crossing Initiative, surveyed 7 culverts, including the 2 railroad culverts in August 2019 to provide support and information for this project. The results of the survey can be found on the New Hampshire SADES Stream Crossing Viewer,https://www.nhsades.com/stream-crossing-viewer and the NH Aquatic Restoration Mapper(http://nhdes.maps.arcgis.com/apps/webappviewer/index.html?id=21173c9556be4c52bc20ea706e1c9f5a).A summary report detailing the hydrologic assessment and drainage analysis, including the railroad culverts, will be submitted to the LWA for review and approval by NHDES.
