<<Folks: One of my research areas is livestock:watercourse
interactions, and one of the issues that I cannot seem to come to
terms with is how much of an improvement is actually achieved by
various improvement/intervention schemes for improving
downstream water quality. I'm specifically interested in non point
source types of contamination - not industrial effluent or sewage
treatment plants, but diffuse sources, like uncontrolled cattle
access, tile drainage, and septic systems.>>>>>>
The Chesapeake Bay Program should have the kinds of data you're
looking for. It took me a couple of minutes to find their Water Quality
for one aspect of their water quality monitoring program.
I found this and other documents/pages by searching their page using the
words: data improvement.
In addition to monitoring water quality in the Bay itself, individual
tributaries of the Bay are monitored. The Bay Program and the states
within the watershed have been implementing practices and monitoring
results since about 1984.
I don't know if you'll find the data you seek on results from
individual practices... After some searching of their web site, I
suggest contacting them directly.

FY '99 Monitoring Subcommittee Workplan (July 27, 1998)
The mission of the Monitoring Subcommittee (MSC) is to characterize the
present state of the Bay and tributaries, determine trends, and increase
our understanding of processes controlling water quality, habitat and
living resources. In FY'99, the MSC will be working to continue to improve
data access and to accelerate interpretation and distribution of the
findings' of data analysis using different formats and vehicles. The
workplan focuses on the several distinct but related activities that are
necessary to achieve these objectives. These include sample collection and
analysis, quality assurance, data management, data analysis and improved
