D&K water resource professionals are thoroughly familiar with the hydrology, hydraulic, and physical characteristics of the Northeast. Our teams include fluvial geomorphologists, wetland scientists, hydrologists, and hydraulic engineers who are supported by permitting specialists, structural engineers, construction phase staff, land surveyors, and landscape architects. We offer a comprehensive understanding of state and federal regulations and…
D&K’s structural, dam, civil, water resource, mechanical, and electrical engineers support the production of hydroelectric power. We assist with capital improvement plans, provide emergency response and forensic analysis, perform FERC 12D inspections, improve facility safety for maintenance activities, develop operations and maintenance programs, assist with maintenance projects, and provide construction phase services. Project experience includes…
DuBois & King provides investigation, analysis, planning, design, and construction phase services to dam owners and conservation groups. We have developed a common-sense approach that provides cost-effective solutions for removing dams and restoring organism passage and sediment transfer along natural channels. D&K’s dam and water resource engineers are supported by our surveyors, wetland scientists, geomorphologists,…
D&K’s dam teams offer a full complement of technical services to dam owners: investigation, hydrologic and hydraulic studies, dam breach analyses, emergency action plans, needs analyses, flood damage surveys, subsurface investigations, evaluation of alternatives, cost estimating, community coordination, state and federal permit assistance, design, plans and specifications, and construction administration. D&K dam engineers are supported…
A recently completed Hazard Mitigation Plan identified flooding as a high risk for the County. Since 1996, approximately 50 flooding events occurred in the County, including flooding from an ice jam in January 2018 and heavy rainfall in August 2018. As a JV team partner, D&K conducted a Supplemental Watershed Plan and Environmental Document (Plan-ED) for…
At the Gorge Hydroelectric facility, power transmission lines cross the Winooski River close to the dam spillway presenting a substantial icing issue (from spillway spray) for the conductors. The facility’s staff regularly used a nearby utility bridge to stage ice removal activities, and the client was interested in modifying the transmission line to reduce or…
The Mad River Valley is a rural though populous region characterized by steep slopes, narrow river channels, and a relatively high level of transportation infrastructure and building stock along valley floors and roads accessing resort areas. D&K worked with the CVRPC to survey the area and develop a study that cataloged the hydrology and hydraulics…
The Baker River Site 8 dam is a 1,462-ft-long by 63-ft-high dam with a maximum storage capacity of 4,750 acre-ft and is fed by a 15.58-sq.-mi. drainage area. The dam uses a vegetated auxiliary spillway to pass high flows, and the main spillway system consists of a concrete riser and a small stilling basin. Constructed…
The Hooksett Hydroelectric Project includes a 1.6 MW run-of-the-river hydroelectric power generation dam that is a barrier to aquatic organism passage (AOP), including Blueback Herring, American Eel, and American Shad. D&K worked closely with officials from the U.S. Fish and Wildlife Service and the National Oceanic and Atmospheric Administration regarding the details of the design,…
