Konitor oandidate aites. <br /> <br />Rationale <br />In order to determine the suitability of restored floodplain <br />habitats for use by razorback suckers and other listed fishes, <br />the degree of selenium (and other inorganics) contamination in <br />several key ecosystem components must be determined. Moreover, <br />general habitat characteristics such as water quality, sediment <br />texture, and primary production should be assessed in these <br />sites. This information is needed for developing future research <br />strategies to assess the suitability of these restored sites as <br />razorback sucker habitats. <br /> <br />Procedure <br />A comprehensive survey will be attempted to determine the <br />present level of selenium (and other inorganics) contamination in <br />the two candidate restoration sites before the water control <br />structures are installed. This monitoring effort will be <br />continued after remediation measures have been implemented to <br />determine if concentrations of these contaminants have changed in <br />response to these measures. In addition to selenium, the other <br />inorganics to be monitored at the sites will be determined after <br />consultation with contaminant experts from the U.S. Fish and <br />Wildlife Service and U.S. Geological Survey. This monitoring <br />program will also include measurements of general water quality <br />parameters, sediment texture, and water and sediment discharge <br />into and out of each restoration site. The major components of <br />the monitoring phase are as follows: <br /> <br />1. Establish sampling sites in each candidate restoration <br /> <br />2 <br />
