<br />. <br /> <br />. <br /> <br />reconstruct a new C stream type in the existing F and 0 channels. Option 3, Priority 3: Reconstruct <br />a B stream type into the existing F and 0 channels. <br /> <br />A combination of Option I and 2 has been accepted by general consensus of the landowners and the <br />ARWRP. <br /> <br />The 8 mile reach between Gunbarrel Road and State Hwy. 371, (Segment 2 or the scope of work <br />area) was selected as a priority area because it contains the highest concentration of unstable Ieaches <br />of the whole Alamosa River. The major channel straightening of the early 70's was conducted in this <br />reach. The majority of the irrigation diversion structures are also located here as well. This stream <br />is classified as F3 and 03 stream types <br /> <br />Stabilization will involve changing the morphology of the stream channel. This will require <br />reshaping the stream to create meander bends with pools and riffies. It will also involve <br />reconnecting the stream with the floodplain. The Conceptual Plan recommends reestablishing the <br />preexisting channel (prior 1970) wherever possible. The project intends to follow this <br />recommendation. <br /> <br />Rock vein structures, placed in the channel's outside bends, will redirect the velocities towards the <br />middle of the stream reducing the shear stress on the stream banks. The stream banks will be re- <br />vegetated with willows and tress. An alternative grazing strategy, involving fencing, will be <br />implemented. Irrigation headgates and diversions will be re-aligned and changed, if necessary, to <br />complement the natural dynamics of the stream. Reducing stream bank erosion near bridge <br />structures will involve consultation with the County's engineer to develop a bridge design that will <br />prevent further cutting into stream banks adjacent to bridges. <br /> <br />The project will be using natural materials and working with the natural stream dynamics. In <br />essence, the restoration effort will mimic what happens in nature. Through this effort, the natural <br />evolution of the stream will be shortened about 100 years. The effort will also create a fish habitat, <br />a swimming hole, a riparian area for livestock and wildlife, and a wetland for water fowl. <br /> <br />This restoration effort has been an ongoing process since 1995. Most of the residents in the area are <br />aware of the project's activities. In 1999 and 2000 the ARWRP was successful in acquiring signed <br />or verbal agreements to do the restoration from all the landowners in the project area. Many ditch <br />companies have given verbal approval and some are waiting for the final design to make a decision. <br />All the ditch companies interviewed so far admit that are problems with their systems and are <br />willing to look at alternatives. <br /> <br />The restoration process also involves the following: <br />* Secure participant permission pertaining to all activities associated with the project.
