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

Upgrade EDAS
• Enter habitat data
• Upgrade EDAS to migrate data to STORET 2.1
• EDAS training

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
![Page 7: Colorado EDAS Enhancement and Index Development 2004](https://reader033.vdocument.in/reader033/viewer/2022052603/56812ef8550346895d949956/html5/thumbnails/7.jpg)
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.
Data entry
![Page 8: Colorado EDAS Enhancement and Index Development 2004](https://reader033.vdocument.in/reader033/viewer/2022052603/56812ef8550346895d949956/html5/thumbnails/8.jpg)
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
![Page 9: Colorado EDAS Enhancement and Index Development 2004](https://reader033.vdocument.in/reader033/viewer/2022052603/56812ef8550346895d949956/html5/thumbnails/9.jpg)
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
![Page 10: Colorado EDAS Enhancement and Index Development 2004](https://reader033.vdocument.in/reader033/viewer/2022052603/56812ef8550346895d949956/html5/thumbnails/10.jpg)
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

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

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