. . . The CWCB has been heavily involved with providing technical assistance to Otis. This goal of this particular effort is to produce a new floodplain delineation study for a tributary that has caused past flooding in portions of the cormmmity. New hydrologic analyses were established to re-defme the peak flows coming into tOWll. The draft floodplain delineation study has been completed and submitted to the tOWll. Once that study has been finalized and accepted by the tOWll, the consultant will present the reconnaissance study, which outlines various flood hazard mitigation options for the south side of Otis. 6. Alamosa-La Jara Water Conservancv District - Field Survev and Hvdraulic Aualvsis Authorization: LongBiIl GrantAmount: $16,000 Water Source: N/A Type: Field survey & hydraulic analysis Location: Alamosa River in & around Capulin Project Manager: Brian Hyde This project is funding the necessary field surveys to provide hydraulic cross-sections for a 5-mile reach of the Alamosa River in and around Capulin and the completion of a hydraulic analysis of flooding conditions in that stream reach. The reach is the subject of a separate CWCB grant for the design and construction of stream restoration improvements. The hydraulic analysis will determine the flow capacity of the existing stream channel and bridges. In the future, modifications designed as part of the stream restoration project can be tested hydraulically prior to construction by simply modifying the hydraulic model. The field surveys have been completed and the hydraulic analysis has been conducted. 7. South Platte Diversion Structure Inventory Proiect Authorization: Long Bill Water Source: South Platte Location: Weld County Grant Amount: $30,465 Project Typ~: Structure Inventory Project Manager; Tim Feehan The Colorado Water Conservation Board is currently evaluatiug the existing condition of various diversion structures along the South Platte River. The limits of the diversion structure inventory project within the South Platte Basin are from the City of Henderson to the State Line. The information being obtained in the field include visual site inspection of the structure, documentation ofthe structure condition, type, and size, digital photos, GPS coordinates, and repair/replacement costs where warranted. The final product developed will be used as a marketing tool by the Water Supply, Planning, and Finance Section staff to inform various ditch companies of the condition oftheir diversion structure, along with a possible funding solution to have it repaired or replaced. In April of2002, the Colorado Water Conservation Board entered into a Contract with the Farnsworth Group, Denver, Colorado, to evaluated the condition ofthe existing diversion structures along the South Platte River, from the City of Henderson to the State Line. The State of Colorado Division I Engineer's Office in Greeley, Colorado has broken this area doWll into three separate districts; District 1, District 2, and District 64. Currently the Farnsworth Group has completed all the inventory work for District 2, which incorporates an area along the South Platte from the City of Henderson to the City of Keensburg, and they are currently in the field working on District I. The consultant is expected to have all fieldwork completed by the September of2002, with the final report being completed by November of 2002. . All project funds for 'fiscal year 2002 have been expended. Remaining funds that are not expended to complete the inveutory along the South Platte will be used to inventory the existing diversion structures along the Arkansas River, from approximately the City Fowler to the State Line. 8.
