Demaske Reservoir Shoreline Protection and Riparian Restoration (CO) 2017


OVERVIEW: Demaske reservoir is proposed for construction in 2018 near Windsor, CO.  Shoreline protection, grading, sediment management and protection of riparian and wetland areas are key not just to create a self-sustaining, vital ecosystem but for the health of the human water supply from this 40 acre reservoir. AloTerra’s design incorporates eight hydroseres to encourage species diversity, shoreline stability, and biological filtering of sediment-laden ditch water entering the reservoir, designing the forebay grading plan and wetland restoration to provide for biological filtering.  Islands and structural vegetation to hide riprap address aesthetic considerations but also increase shoreline complexity to improve fisheries and reduce wind-induced bank erosion. The design also improves lake circulation, optimizes depths and shelf access, winter ice-free zones, strategic locations for shading, and other water quality improvement.


ALOTERRA designed for structural and functional aspects including forebay grading of the reservoir’s littoral zone and riparian area, riparian and wetland area revegetation design, sediment and erosion mitigation, fisheries improvements, and optimal ecosystem management through bioengineering and terrain design. Aesthetic integration included structural vegetation for concealment of fascines, riprap, and other bioengineering implements.
