| Relation | Central Utah Project; Western Waters Digital Library; water quality monitoring will continue downstream of strawberry tunnel sixth water aqueduct and diamond fork creek outlet to determine potential dissolved oxygen concentration impacts and how far downstream low dissolved oxygen levels are found district mitigation commission if low dissolved oxygen levels are found downstream from tunnel outlets baffles or oxygen aerators should be installed to bring dissolved oxygen concentrations up to levels that are not detrimental to fish and other aquatic resources district special status species monitoring during the construction period prior to project operation will vill continue to establish a credible baseline district data collection following project implementation will include measurements of actual stream elevations relative to ute ladies tresses colony locations if there are significant discrepancies the model should be modified and a new impact assessment completed additionally the joint lead agencies should perform aerial mapping at a resolution sufficient to record stream channel geomorphology vegetation community and orchid colony locations in several year intervals to help better understand changes and evaluate their significance in relation to restoration and conservation goals district mitigation commission changes in vegetative communities in occupied or potentially suitable orchid habitat will be measured along diamond fork creek and spanish fork canyon district mitigation commission the fhe natural variation in ute ladies tresses demography population vigor and habitat will be characterized under baseline conditions and under actual operations district mitigation commission the three forks colony will be monitored to better understand the process of loss of viability and eventual extirpation of colonies monitoring should focus on the rate of loss identifying which parameters are best to measure to determine if loss is occurring etc NEti netigation mitigation gation gatlon commission conservation measures in addition to altering flows and rescuetransplant rescue transplant should be considered such as vegetation manipulation providing supplemental water to colonies and mechanical reconfiguration of portions of the stream channel or floodplain flood plain surfaces if monitoring data show streamflow stream flow hydrology is adversely affecting the ute uteladies ladies ladles tresses population mitigation commission if pollination is determined to be a limiting factor to longterm long term orchid viability and successful colonization of new habitats then the joint lead agencies will consider actions to enhance pollinator habitat or numbers as appropriate mitigation commission A methodology should be developed that will monitor changes in ute ladies tresses habitat quality and the methodology should be used to establish habitat quality parameters of the population mitigation commission population viability parameters and red flag conditions should be established for the habitat quality parameters mitigation commission timing for performing the most accurate canyon wide ute ladies tresses counts should be evaluated mitigation commission the relationship between river hydrology depth to soil water soil moisture soil characteristics and ute ladies tresses colonies should be correlated deti NEti mitigation gation gatlon commission A 13 diamond fork propos proposed ed action modifications EA |
