Presentation Transcript

  1. Central Plains Center for BioAssessment An overview of our projects. Debbie Baker Sept. 2004

  2. History • Facilitate coordination of regional-based nutrient criteria and biocriteria for waterbodies of USEPA Region 7.

  3. Region

  4. Nutrient and Biocriteria Workgroups • EPA's Clean Water Action Plan 1998 • Goal – protect aquatic life from nutrient overenrichment. • USEPA Region 7, Kansas City • Nebraska • Iowa • Kansas • Missouri

  5. Nutrient Criteria • Goal – establish draft benchmark nutrient criteria for lakes, streams, and wetlands of the US EPA Region 7 and the Central Plains Region.

  6. Streams

  7. Nutrient Criteria cont’d

  8. Biocriteria workgroup • Goal - adoption of narrative biological criteria as part of State water quality standards. • Annual meetings (workshops) available on website. • Symposia open to others. • Currently macroinvertebrate database to examine reference stream conditions.

  9. National Park Service • Heartland Network Inventory and Monitoring Program • Develop monitoring plan for surface waters • Literature, database, GIS, analyses • 15 parks

  10. DO monitoring • Kansas TMDL streams • Measure DO levels in water column and oxygen demand (BOD and SOD) • Long-term productivity at Soldier and Cedar Creeks

  11. REMAP • KDWP sampled streams 2000/2001 • LeeAnn taxonomist for 2001 bugs • KU museum ID fish • Liz format data • Raw data  metrics

  12. Physical Habitat Variables(1) Channel morphology • Mean thalweg depth (m) (xdepth) • Standard deviation of thalweg depth (cm) (sddepth) • Mean wetted width (m) (xwidth) • Mean wetted width x depth (m2) (xwxd) • Mean residual depth (m2/100 m reach length)=cm (rp100) • Mean bankfull width (m) (xbkf_w) • Mean bankfull height (m) (xbkf_h) • Mean incision height (m) (xinc_h) • Channel Sinuosity (sinu) • Water Surface gradient over reach (%) (xslope) NDEQ Dec. 2000

  13. Mean Bankfull Height (m) From All Basins In Nebraska, 1994-95 REMAP Perennial Sites = box Hand-picked Sites = triangle NDEQ Dec. 2000

  14. Wadeable Stream Assessment • National EPA study on over 500 randomly chosen streams • Follow-up to study in Western and Atlantic states • REMAP methods • Sample TX and NE streams • Sort and identify macroinvertebrates from TX, NE, KS, MO, and OK

  15. Outreach
