ARS Watershed Research
•USDA has conducted watershed research since early 1900’s
•Many watersheds are still operational
•Data managed locally and disseminated independently
•Accessibility has limited visibility and utility of these data

CEAP Team 1 Goal
To develop and implement a web-based data system to organize,
document, manipulate, and compile climate, water, soil, land-
management, and socio-economic data from ARS research watersheds
for assessment of conservation practices and other hydrologic
analyses

Challenges
•Data not uniform across (or within) sites•No single organizational unit has
necessary knowledge, skill set or mandate
•Communication within heterogeneous team
•Competing demands on time for all team members
•Uncertain funding beyond annual budgets
![Page 7: Watershed Data System: Overview Jean L. Steiner, E. John Sadler, Jin-Song Chen Greg Wilson, David James, Bruce Vandenberg John Ross, Teri Oster, Kevin.](https://reader036.fdocuments.in/reader036/viewer/2022062516/56649d925503460f94a78810/html5/thumbnails/7.jpg)
Unique aspects of system
•Flexible to accept highly heterogeneous data
•Ability to capture and communicate rich descriptive data
•Bringing time-series and other measurement data into spatial context
•SiteID, DateTime, and Watershed ID as primary keys
