Central Plains Center for BioAssessment

The Central Plains Center for BioAssessment focuses on coordinating nutrient criteria and biocriteria specific to water bodies within USEPA Region 7. Key objectives include protecting aquatic life from nutrient overenrichment, establishing benchmark nutrient criteria for various water bodies, and adopting narrative biological criteria within state water quality standards. We manage a macroinvertebrate database to assess stream conditions and conduct extensive monitoring through the Heartland Network to evaluate surface water quality across multiple parks. Annual workshops and symposia provide collaborative opportunities and updates on ongoing research.

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
