Located along the Konkapot River, the Berkshire National Fish Hatchery maintains lake trout brood stocks for restoration efforts in the Lower Great Lakes and raises brook trout for local recreation and educational programs throughout Berkshire County. The existing water supply system consisted of three shallow gravel wells and two springs that are connected, piped, and…
Sucker Brook was a deeply incised stream channel that threatened nearby infrastructure and sent an estimated one ton of phosphorus per year downstream toward Lake Champlain. The project goals included a reduction of sediment loading and erosion and the restoration of aquatic and riparian habitat while minimizing construction and maintenance costs. D&K prepared conceptual and…
The New Hampshire Department of Environmental Services identified the 1861 concrete and masonry Union Village Dam as high-hazard and deficient in a number of areas. The owners’ preferred option was to remove the dam to reduce potential hazards and remove a hydraulic and aquatic organism passage barrier from the river, restoring the river to a…
The goal of this project was the removal of Stone Pond Dam and associated structures, the restoration of Scott Brook to a free-flowing condition, and the removal of an unnatural barrier to aquatic organism passage (AOP). D&K developed a study and provided a removal design that considered H&H, sediment transfer, and soils and identified alternatives…
The Cross Brothers Dam was no longer used for a long-defunct mill, and the impoundment had silted into the dam’s crest. The dam, built in 1924 and classified as a Low-Hazard dam by the State of Vermont, was a complete obstruction to aquatic organism passage with the potential to further damage water quality. D&K provided…
Otter View Park is an ADA-accessible public park that consists of a series of trails located on 17 acres next to the Otter Creek. The park provides pedestrian access through a variety of natural settings, such as upland meadow, cattail marsh, wetland shrubs, and floodplain forest. D&K designed the park and pathways; performed topographic and…
The City of Laconia’s Parks and Recreation Department sought to create a new infill park on Lucerne Avenue. The park included a restroom building, an amphitheater, a playground, and a pavilion. D&K worked with subconsultants to accomplish Low Impact Development practices and provided part-time construction observation services, concrete foundation testing observation, and contract administration services.
An aging concrete and masonry dam was deemed structurally deficient by state regulators, and the owners could not justify the expense of reconstruction. D&K connected the owners with the NRCS to fund the construction, which included the removal and disposal of the dam and active restoration of the stream channel. Our team designed the removal…
The Cabot-Danville US 2 Segment 1 highway stormwater improvements included relocating a reach of Molly’s Falls Brook. The project required site inspection coordinated with the Vermont Agency of Natural Resources District Fisheries Biologist, Stream Alteration Engineer, and VTrans representatives. To relocate the brook, D&K collected site data and developed a design utilizing hydraulic engineering and…
