to dissipate energy and deposit sediment. Structures would direct peak flow into constructed riparian areas within the existing alluvial stream channel to further filter sediment. 2. 2.2 This targeted, watershed approach is an innovative solution. 2. 3 Responsible agencies: 1) Stabilization of Crystal River streambanks will be addressed through technical assistance from the Colorado Division of Wildlife. These 3 to 5 individual projects are valued at approximately $10,000 each. 2) The U.S. Forest Service and the Colorado Mined Land Reclamation Division (MLRD) collaborated in a detailed onsite inspection of the approximate 290 acres disturbed by the mining operation in Coal Basin. That effort was documented in a Summary Report. The Mined Land Reclamation Board has required that the recommendations of this report be included in a revised permit for the mining operation. Because this aspect of the problem is addressed through regulation it is not appropriate to include in the overall costs of the project. 3 ) In-stream structures in Coal Creek will be designed by Northwest Colorado Council of Governments (NWCCOG) with review by U.S. Forest Service. NWCCOG will also administer, supervise, and provide data analysis for the project. The cost for this element of the project, including construction contractor, is $21,828. Pitkin County will provide some of the necessary equipment, labor, materials and transportation as an in-kind match valued at $10 , 300 for this aspect of the project. Colorado Division of Wildlife (CDOW) will perform macro-invertebrate sampling and monitor habitat improvement indices, an in-kind estimated at $ 4 , 200. Laboratory evaluation of biological samples will cost $3 ,000 and are included in this grant request. 2.4 NWCCOG will contract with the state. 3 . Monitoring/Evaluation Procedures 3 .1 Utilize the F statistic to determine if dissolved and suspended sediment in the Crystal River at Carbondale (CDH station 14010004005) is statistically improved relative to the station just upstream of Coal Creek (CDH station 14010004008) . These sampling sites have twelve years of data which portray sediment concentrations above and below Coal Creek. Additional monitoring will include continued macro- invertebrate sampling (3 years of sampling data exists) to assess improvements in biologic diversity with a goal of bringing the DAT diversity index into the excellent range (18 - 26) , and utilizing stream index sites to evaluate habitat improvements. 3. 2 Monitoring program design is for up-stream-down-stream sampling of sediment and macro-invertebrates. 3 . 3 Information from this project will be utilized to: determine the success of the project as measured by the stated goal; evaluate the effectiveness of targeting of resources in nonpoint source watershed improvement projects for future activities; provide information to assess whether further remediation, specifically upstream of Coal Creek, is necessary on the Crystal River; to assist the Division of Wildlife in decision making regarding overall fisheries management of the Crystal River.
