<br />. <br /> <br />. <br /> <br />overgrazing and the misplacement of structures, such as bridges and irrigation diversions. <br />The cost to stabilize this reach has not yet been determined. Three to four miles need <br />extensive treatment. <br /> <br />Segment 2. The Gunbarrel Road to below Co. State Hwy 371. This segment is 8 miles <br />long. It includes the five mile "scope of work" from the Gunbarrel Road to County Road <br />10. A major re-channeling project was conducted on this reach during the early 70's. The <br />stream has been classified as F3 and 03 stream types using" Stream Classification" <br />Dave Rosgen (1994). Most ofthe irrigation diversions are concentrated in this area as <br />well. In this 8 mile reach, five or six miles will need extensive treatment. Estimates vary <br />between $20.00-$28.00 a foot. <br /> <br />Segment 3. This includes 2.5 miles of stream below County Rd. 13. This area has <br />undergone extensive re-channeling, and the landowners intend to maintain this alteration. <br />The project will not address this area. <br /> <br />Segment 4. This area begins a mile and a half above U.S. Hwy. 285 and is downstream <br />and adjacent to the altered stream segment 3. The meanders were straightened and the <br />stream altered to accommodate the upstream landowners. The landowners in this segment <br />have expressed their desire to place the stream back into the original streambed. To put <br />the stream back in the original course will be costly, and there is a risk factor due to the <br />activities in Segment 3. The ARWRP would have to consult with Rosgen to determine <br />the best approach. The project does not want to exclude anyone who wishes to <br />participate. However, the project may have to solicit another funding source to pay for <br />this portion of the project. This segment is approximately 2 miles long. <br /> <br />PROJECT DESCRIPTION <br /> <br />In 1998 the ARWRP hired Dave Rosgen, Wildland Hydrology, Pagosa Springs, Co. to develop a <br />conceptual plan for the river. An assessment of the stream's condition was made at this time. <br />"The Conceptual Plan for the Alamosa River" (Dave Rosgen, 1999), identifies the most severe <br />and unstable reaches of the Alamosa River between below Terrace Reservoir and Highway 285. <br />General treatment recommendations are included in this plan. The stream was classified at the <br />same time using" Stream Classification. Applied River Morphology", (Dave Rosgen, 1994). Of <br />the 20 mile reach between the Terrace Reservoir and U.S. Hwy 285, it is estimated that 10 miles <br />of the river will need extensive treatment. This plan has been a valuable tool in explaining to <br />participants and potential funding sources what the restoration effort will require. At request, <br />The Conceptual Plan is available to any interested party. <br /> <br />The Conceptual Plan provides three different engineering design options to return the Alamosa <br />River to its natural functioning condition. Option 1, Priority 1: Place the stream back into the original <br />course (prior to river straightening) and re-connecting the stream with the original flood plain. <br />Option 2, Priority 2: Place the stream, where eveI possible in the original channel bed and <br /> <br />Page -3- <br />
