Rio Blanco Restoration Project
The Rio Blanco River Restoration Project,
Phase III reconstruction has begun with a $95,000 grant from the Natural
Resources Conservation Service (NRCS) and matching funds from, among other
organizations, the San Juan Water Conservancy District ($20k) and the
Southwestern Water Conservation District ($25k). Actual work will commence in
the Spring of 2009.
As a result of the legislated by-pass
flows of the San Juan-Chama Transbasin Diversion that became active in the
spring of 1971, the
underwent severe hydrological changes. During the ensuing years the river
became unable to transport sedimentation downstream to the mouth of the
legislated bypass flows were insufficient to support the fish habitat due to
the wide and shallow streambed. The purpose of the Restoration Project is to
modify the river channel (approximate
nine mile reach of the Rio Blanco above its confluence with the San Juan
River) to improve water quality and restore fishery and river habitat.
Phase I of the Project involved restoration to a
demonstration segment of the river. With successful results from the
demonstration segment, Phase II was completed in 2004. Phase II tied the
initial demonstration segment with the upper reach of the
3.25 miles of river have been restored. The intent of Phase III is to restore
an additional 1-1.25 miles of the river.
