Presentation A8 Maxwell

  1. 1. City of Wichita Falls Wichita River Biological Monitoring Plan Blair Maxwell
  2. 2. Introduction <ul><li>This study was used to generate data useful to compare general biologic trends on the Wichita River segment 0214. </li></ul><ul><li>The data gathered from this research in conjunction with other biological data will evaluate possible relationships between physical characteristics of the stream and biological trends. </li></ul>
  3. 3. Wichita River Segment 0214
  4. 4. Purpose
  5. 5. Background <ul><li>The City of Wichita Falls has, as of February 2009, put into commission the reverse osmosis facility which discharges a brine effluent into the Wichita River segment 0214. </li></ul><ul><li>The reverse osmosis system was built for the City of Wichita Falls as a treatment process to produce municipal potable water for Wichita Falls and surrounding cities. </li></ul>
  6. 6. Lake Levels
  7. 7. Research Methods <ul><li>Data was collected of general habitat, fish, and macro-invertebrate community structure on multiple locations of segment 0214 of the Wichita River. </li></ul><ul><li>Each sample of macro-invertebrate and small fish were collected using a D-frame net. The collector used the kick net for 20 minutes, and all sediment and biologic life was placed in a five gallon bucket. </li></ul><ul><li>Then the sample was taken to the lab for identification. </li></ul>
  8. 8. Results <ul><li>Assessments for fish and macro-invertebrates give valuable insight into the biological health of streams in the Wichita River. </li></ul><ul><li>Little information exists on the biological communities of this geographical region, which hinders long term comparisons between biological assessments. </li></ul><ul><li>Samples collected after the brine line is in place will allow for comparison in any differences in water quality. </li></ul>

  12. 12. Conclusion <ul><li>Once more data is collected after the brine discharge has been in place for a few months, any changes in biological environments will show up in future collections. </li></ul><ul><li>As far as the data that was collected no statistical relevant changes were noted. Also, no morphological changes were seen within the samples collected at all three sites. </li></ul>
