Effects on Pallid Sturgeon Habitat <br />1) Water management effects on habitat <br />Data needs: <br />0 USGS gaging stations at Duncan, <br />0 Quantitative analysis <br />Annually, ongoing <br />Discharge <br />North Bend, Louisville and Grand <br />Island, at minimum <br />Data needs: <br />0 Current lower Platte studies by UNL <br />0 Trend analysis <br />At least twice <br />Water Depth <br />Transects across lower Platte'- <br />0 Sediment/vegetation <br />annually; 10 -13 years <br />Channel "roughness" <br />model (eventually) <br />Water velocity <br />Turbidity <br />Sediment load <br />Sediment concentration <br />Grain size <br />Temperature <br />Pallid sturgeon occurrence in the lower <br />Platte <br />B. Effects on pallid sturgeon <br />1) Water management effects on spawning, <br />fry survival, etc. <br />Data needs: <br />Quantitative analysis <br />Annually, ongoing <br />Discharge, quantity and timing <br />USGS gaging stations at Duncan, <br />Trend analysis <br />Pallid sturgeon occurrence in the <br />North Bend, and Louisville <br />lowerPlatte <br />Current lower Platte studies by UNL <br />I Data analysis will be included as part of the R2 -1 study protocols <br />'- Location and type of all permanent transects (sediment, channel morphology) will be chosen /coordinated for efficiency of data collection and to take best advantage of <br />historical data <br />21 <br />
