Central Plains Center for Bio. Assessment An overview of our projects. Debbie Baker
History • Facilitate coordination of regional-based nutrient criteria and biocriteria for waterbodies of USEPA Region 7.
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
Nutrient Criteria • Goal – establish draft benchmark nutrient criteria for lakes, streams, and wetlands of the US EPA Region 7 and the Central Plains Region.
Nutrient Criteria cont’d
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.
National Park Service • Heartland Network Inventory and Monitoring Program • Develop monitoring plan for surface waters • Literature, database, GIS, analyses • 15 parks
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
REMAP • • • KDWP sampled streams 2000/2001 Lee. Ann taxonomist for 2001 bugs KU museum ID fish Liz format data Raw data metrics
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 (m 2) (xwxd) Mean residual depth (m 2/100 m reach length)=cm (rp 100) 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

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
