Aquatic impacts from operation of three midwestern nuclear power stations: Fort Calhoun station, Unit No. 1 environmental appraisal report
Fort Calhoun Station, Unit 1, is located on the west bank of the Missouri River in Washington County, Nebraska. The station, a nuclear powered generating facility producing 475 net megawatts, utilizes a once-through cooling design. The station influences the aquatic biota of the Missouri River vicinity in several ways. The heated discharges of the station were found to have no significant impacts to fish, periphyton, and benthic macroinvertebrates. Minor effects to phytoplankton were noted in warm summer months at the point of discharge. An estimated 227,900,000 fish larvae were entrained annually from the river's ichthyoplankton community, the majority identified as freshwater drum. Fort Calhoun Station impinged an estimated 170,882 fish annually, large numbers of which were freshwater drum and gizzard shad with potential losses to channel and flathead catfish. The station was shown to have little impact on the zooplankton community.
