  1. Colorado EDAS Enhancement and Index Development2004 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. Data entry Geospatial Coverage • 435 Stations • 505 Benthic Macroinvertebrate Samples • 161 Habitat Samples • 55 Field Water Chemistry Samples

  5. Data entry 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

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

  7. Data entry 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

  8. Data entry 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.

  9. Upgrade 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

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

  11. Upgrade Mississippi DEQ Data Entry forms

  12. Upgrade: Reports

  13. Upgrade Reports

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