SLR Honored by ACEC-NH

Marston-Finn Conservation Dam

Windham, NH – The SLR-designed Marston-Finn Conservation Dam in Windham (formerly Moeckel Pond Dam) was recently awarded an Engineering Excellence Silver Award by the American Council of Engineering Companies, New Hampshire chapter.

The annual awards celebrate excellence in the consulting engineering profession and recognize the best engineering works of the past year.

Bedford-based SLR (previously Milone & MacBroom, Inc.) oversaw design of the dam’s required assessment, design of improvements, and construction inspection, with support from project partner The H. L. Turner Group Inc. for hydrologic and hydraulic analyses.

The design team, led by Charles Eric Teale, principal geotechnical engineer at SLR, was tasked with developing a solution to increase the spillway capacity without increasing the dam footprint, lowering the impoundment, or increasing the downstream flood flows while simultaneously preserving historic attributes of this over 200-year-old grist mill dam. The result was a unique, sustainable, and economically prudent design solution utilizing a labyrinth weir spillway.
