Aerial Flyovers for TMDL Watersheds
Aerial flyovers were completed for selected TMDL watersheds to analyze
the impaired streams and streambanks. Video taping was completed by Fostaire
Helicopters, Sauget, IL, using a camera mounted beneath a helicopter to
record data from just above tree top level in DVD format for evaluation
and assessment.
After videotaping the stream, the DVD tapes were processed by USGS to
produce a georeferenced DVD showing flight data and location. Next, USGS
identified features from the video and created shapefiles containing the
GPS location, type of feature identified, and the time on the DVD to allow
cross referencing. The shape-files along with the DVD were then used to
identify and locate the points where ground investigations were needed
to verify aerial assessment assumptions and gather additional data.
A report for each watershed was developed by Wayne Kinney (the Department
of Agriculture) with the assessment and treatment recommendations. A Soil
and Water Conservation District in each TMDL watershed was given a copy
of Aerial Flyover DVD and the Aerial Assessment Report. Below is the SWCD
County office that received copies of both the DVD(s) and the Report.
For a copy of the Aerial Assessment Report (in PDF), click on the TMDL
watershed below and save a copy of the report or it can be printed. If
you would like your own copy of the Aerial Flyover DVD, please contact
The Prairie Production Group at (217) 359-4675. There will be a small
cost for each DVD copy.
