• Facilitate coordination of regional-based nutrient criteria and biocriteria for waterbodies of USEPA Region 7.
History
Region
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.
Streams
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
• LeeAnn 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 (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)

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
