Pecos River near Pecos, NM – Kooi

Historic degradation and widening of the river had created shallow flow conditions and limited aquatic habitat for salmonids. Riverbend’s geomorphic analysis documented relatively recent channel bed lowering and straightening of the channel plan form as a result of the incised conditions. The design solution included narrowing the low flow channel of the river, excavating deep pools, adding rock structures and woody debris structures for fish habitat, grading of alternating gravel bars along the active channel, planting of obligate wetland species and riparian adapted native ornamental shrubs to create a parallel riverine wetland.
