| Relation | Central Utah Project; Western Waters Digital Library; page 2 project description the PRRP proposed action riverine habitat restoration would reconstruct and realign a majority of the existing river channel and floodplain flood plain system between jordanelle Jor danelle dam and deer creek reservoir in a meandering riffle pool sequence to recreate a geomorphically geornorphically morphically geo stable river channel the new channel would be contiguous with the floodplain flood plain and will function in dynamic equilibrium with the current valley and hydrologic conditions most existing levees would be removed or breached as long as 100 year flood protection is provided by the expanded floodplain flood plain or a setback levee A meandering riffle pool channel interacting with a functioning floodplain flood plain would be developed wherever possible in some areas this would be accomplished by incorporating the present channel in others the present channel would be abandoned and a new channel alignment developed where possible the river channel would be allowed to migrate within a designated corridor in response to natural variability in hydrologic or geomorphic factors disturbed areas along the new floodplain flood plain would be initially re vegetated with native plants following construction side channels and ponds would be incorporated into the design throughout the length of the provo river between jordanelle Jor danelle dam and deer creek reservoir the proposed action would incorporate baseline conditions including seven new recreation access points contiguous access to the river corridor for recreational fishing and a minimum instream instrearn in stream flow of 125 cfs cs the proposed action would adversely affect some wetland areas including a portion of the US bureau of reclamation USBR mitigation wetlands and irrigation induced wetlands situated along the river that are currently used for livestock grazing and hay production some riparian wetlands and riverine habitat would be converted to the new river channel the proposed action will necessitate the acquisition of certain lands fencing andor other measures for limiting livestock grazing will be incorporated into pa p1 plans an s fo for r m managing th the e riparian zone wetlands affected by the proposed action would be replaced with wetland habitat created under the proposed action and wetland mitigation the proposed action would provide for longterm long term development of a large riparian woodland along the provo river cottonwood galleries probably would develop in the constructed floodplain flood plain from controlled flooding events these cottonwood galleries would provide vertical structure organic soil development detrital input to the river shading wildlife habitat diversity and other natural components to the riverine ecosystem the channels and ponds would provide additional habitat for amphibians fish and other wildlife under the proposed action the floodplain flood plain would receive flood flows every 2 to 5 years and therefore conditions would be favorable for natural regeneration of cottonwood trees riparian shrubs and other species that are stimulated by periodic scour and deposition of sediments generated from the bed and banks of the river between jordanelle Jor danelle dam and deer creek reservoir the central utah water conservancy district district is responsible for operating jordanelle Jor danelle dam the projected operating regime for jordanelle Jor danelle reservoir described in the 1987 final supplement to the mai mal system final environmental statement was used in the impact analysis for the PRRP this operating regime will ensure the delivery of minimum strearnflows streamflows stream flows of 125 cfs cs and provide the periodic flood regime analyzed in the document requests to modify the flow E 2 |
