The ARS Watershed Assessment Study
Anticipated Products1. Water, soil, management, and economic
data system.
2. Quantification of effects of conservation practices on environmental quality.
3. Validation of models and quantification of uncertainties of model predictions.
4. Evaluation of cost effectiveness of selection and placement of conservation practices.
5. Development of regional watershed models.
Missouri’s project – Mark Twain Lake /Salt River basin
• CEAP focuses on larger watersheds
• Historical data is on a smaller watershed – Goodwater Creek
• Scaling up is a significant part of our research in CEAP
• Some watersheds have very different land uses, which gives us some leverage
The NRCS Special Emphasis
Watersheds Funding by NRCS thru state offices 8 selected in 2004 Focus on specific resource concerns Locations add diversity to other
CEAP watershed studies Technical collaboration with others
CSREES Competitive Grants Watersheds
4 projects funded in 2004, 4 more in 2005
3 year duration Maximum award - $660K/project $3 million (CSREES 2M, NRCS 1M) Competitive external review
CEAP Blue Ribbon Panel
Established to provide external review and guidance to CEAP.
Composed of representatives from the communities that will use CEAP output.
Recommendations:USDA should use CEAP resources to provide
assessments that will inform the 2007 farm bill debate.
CEAP should provide rigorous assessments of options for implementing future conservation programs.
SUMMARYSUMMARY CEAP is mandated by Congress and OMB. ARS-CEAP is a large multi-location project involving
14 watersheds. NRCS Special Emphasis Watersheds involve 8
watersheds focused on specific resource concerns. CSREES Competitive Grants watersheds include 4
projects funded in 2004 and 4 additional projects funded in 2005.
All three watershed programs support the CEAP National Assessment.
An external panel is providing guidance to CEAP direction.

Local Issues - Atrazine
• What appears to reduce Atrazine lost in runoff?• ARS local research results
– Applying less of it– Incorporating after applying it– Having no runoff until it dissipates
• Two of these are management compromises • The other is unpredictable, and approaches
unmanageable
