1. Colorado EDAS Enhancement and Index Development 2004 Tetra Tech, Inc. and Utah State University

2. Goal: improve WQCD’s capacity to incorporate biological data Update and upgrade Colorado’s Ecological Data Application System (EDAS) Build biological assessment and biological criteria tools for Colorado –Multimetric index (IBI) –O/E index

3. Upgrade EDAS Enter habitat data Upgrade EDAS to migrate data to STORET 2.1 EDAS training

4. Geospatial Coverage 435 Stations –505 Benthic Macroinvertebrate Samples –161 Habitat Samples –55 Field Water Chemistry Samples Data entry

6. Data Entry 73 stations –all with Physical Habitat Visual Assessment General Information –47 have additional information Cross Section (flow) Field Water Chemistry Pebble Count Channel Information Data entry completed except for a few needing clarification, quality control check not started Data entry

7. Data Quality Control 100% of data entry will be verified by a 2 nd person (some one other than the data entry person). Any errors will be noted and corrected. Data entry

8. Taxonomic Issues 1245 total taxa Compared with Integrated Taxonomic Information System (ITIS) the USEPA standard for taxonomy; http://www.itis.usda.gov/ –913 matches –332 non-matches Non-standard taxonomic names –sp. –Stage (adult, pupae, larvae, etc.) Will have to combine taxa before analysis Functional Feeding Groups have multiple entries –Metrics written for only a single group not multiple –STORET won’t accept multiple listings Data entry

9. Data Quality Issues One relationship between Benthic Master Taxa and Benthic Data was removed –Have 18 orphaned taxa 476 occurrences (i.e., samples) 3,514 individuals –Will have to find the missing taxa names from bench sheets Some habitat assessments are incomplete (missing a parameter value) so assessment will have to take this into account. Data entry

10. Database Enhancements Will upgrade EDAS to the latest version that has more STORET features –Addition of Project, Trip, and Visit tables and from STORET Will provide a way to migrate data from EDAS to STORET Upgrade

11. Potential Enhancements Data entry –Forms that look and feel like field, lab sheets Reporting features –Creation of reports from data within EDAS Upgrade

12. Data Entry forms Upgrade Mississippi DEQ

13. Upgrade: Reports

14. Upgrade Reports

15. Index development Methods – sampling protocol recommendations Multimetric index RIVPACS (O/E) index (USU) Training

16. Information needed for least stressed identification – GIS based NPDES permits CAFO % Natural vegetation % Urban % Row crop Road density Mining –Active –Abandoned RCRA/CERCLA Hydrologic modification Landfills

17. Information needed for least stressed identification – cont. Habitat Embeddedness % fines Riparian condition Erosion/sedimentation Channel alteration Total score Chemical Conductivity pH SO4 Cl NO3 Total P Metals
