Similarly, river discharge and other habitat parameters will be compared to the abundance <br />of larval fishes collected in drift samples (Reade 2000). Development of habitat preference or <br />habitat suitability criteria for sturgeon and associated species will require comparison of habitat <br />use data collected by this research to independent data from previous PHABSIM analyses and <br />additional information beyond the realm of this proposal. <br />Starting in September 2000 we measured water temperature ( °C), dissolved oxygen <br />(mg/L), conductivity (uS /cm), salinity (ppt), turbidity (NTU),and total suspended solids (mg/L) <br />(APHA 1987) at four sites in the lower Platte basin. The locations of these sites are described in <br />Table 3.1 and shown on Figure 3.1. The sites at Louisville and Leshara are located on the Platte <br />River, while the sites at Greenwood and Waterloo are on Salt Creek and the Elkhorn River, <br />respectively. These sites were sampled weekly through the fall and winter, except when ice <br />conditions made water sampling dangerous. Five temperature recording units were placed at the <br />Louisville site to monitor temperature on a continuous basis. <br />ACCOMPLISHMENTS <br />WATER QUALITY MONITORING <br />Tables 3 -2 to 3 -5 summarize mean, minimum and maximum values recorded for each of <br />the seven water quality parameters measured between January 1, 2001 and March 26, 2002. <br />Temperature maxima exceeded 30 °C at all stations during 2001 and all sites experienced <br />temperature minima of 0 °C during this time period. The lowest dissolved oxygen readings <br />(5.6mg/1) occurred at Greenwood on Salt Creek (Table 3 -4). Conductivity, specific conductivity, <br />and salinity values averaged highest at Greenwood on Salt Creek (table 3 -4). Total suspended <br />15 <br />
