8. North Fork River Improvement Association Authorization: lIB 00-1419 Water Source: N/A Location: North Fork Gunnison River near Paonia Grant Amount: $50,000 Project Type: Stream Stability Design Project Manager: Brian Hyde This project is a Drainage Way Master Planning; Preliminary Drainage Design, Floodplain Delineation Study on Bosley Wash and Stub Ditch in the Grand Valley. The stream experienced three major . flood events in the sununer 1999. HDR Engineering was selepted to perform the engineering work for this project, and a contract has been signed with Mesa County. Work on the project is underway. The study evaluated the flood risks throughout the basins and floodplains, determined the hydrologic and hydraulic characteristics of the study reaches, delineated the flood hazard areas, and formulated flood mitigation measures. A draft report has been prepared that presents the study findings and recommendations. The report is under review by the project sponsors. The study and project will be completed in the sununer of 2002. This project will produce a final design for river stability improvements for a 3 - 4 mile reach of the North Fork of the Gunnison River between Paonia and Hotchkiss. The specific project reach lies within a 15-mile reach of the North Fork, starting upstreiun of Paonia and extending downstream of Hotchkiss, which has experienced severe iustability p~oblems. The project will be the second demonstration project along that unstable reach, with the first having been completed near Hotchkiss. The field surveys and topographic mapping have been completed, fiual engineering design has been completed, and construction of the project fmished. A PowerPoint presentation has been prepared as part of the project to allow others to benefit from the design and construction lessons learned through this effort. A part of the project involved the design and construction of an irrigation headgate facility . that is expected to avoid the problems caused by instability :with more conventional headgate designs. 9. Lower Elk River Flood Association - Elk River Stre~mbank Study Authorization: HB 98-1189, lIB 00-1419 Grant Amount: $25,700 Water Source: Elk River Project Type: Stream Stabilization Study Location: 8 mi. west of Steamboat Springs Project Manager: Larry Lang CWCB contracted with Icon Engineering, Inc. to perform an engineering investigation for the Elk River watershed study and streambank stabilization proNct on the lower one-mile section of the river. The study was completed and the hydrologic and hydraulip characteristics of the watershed and provided engineering recommendations for the stabilization of the ~Ik River streambank upstream of Highway 40 were developed. Following the Icon study, some latidowners aloug the river contracted with an independent consultant and privately funded river restoration work. CWCB staff has no further funding requests or projects on the lower Elk River at this time. The project will be re-opened following local consensus for project goals. 10. Frenchman Creek Floodplain Studv in Holyoke Authorization: SBOI-157 Water Source: Frenchman Creek Location: Holyoke Loan Amount: $25,000 Proj eet Type: Floodplain study Project Manager: Tom Browning The City of Holyoke (City) and Phillips CountY (County) experienced flooding in 1997 when Frenchman Creek and its tributaries overflowed. Funding will help pay for a flood mitigation planning and engineering study to utilize recommendations provided by the Army Corps of Engineers so project design and implementation can take place. The City and County are providing cash and/or in-kind services. . Page 6 001
