River Restoration Results

Restoration efforts are slow this time of year due to the Polar Inversion; plummeting temperatures and water don’t really work well together. Therefore we are focusing on data reduction and analysis.  We have been remiss in this area and we look forward to uploading the data as it becomes available. In order to key in on the data it is important to note that the original restoration effort was viewed as a large scale Pilot Test.  As a result, all samples from this effort use the label PT, e.g. PT1-2 is the second  sample taken during the Pilot Test (Phase I) in Cell 1. Two subsequent phases were initiated and samples are designated with the use the label P2 and P3.

It is also important to note that throughout our restoration effort, our goal was to remove the fine particles that have embedded themselves into the coarse sand and gravel. The TRUST’s effort in sampling and analysis is to perform pre and post sediment sampling followed by grain size analysis. For the purposes of illustration for the web, we will use a ternary diagram modified from Nichols, 1969 that plots the percentages of sand, gravel and mud (fines). We classify mud as all particles smaller in size than a 100 sieve (0.149 mm) which of course includes silts and clays. The TRUST will also perform Sediment Oxygen Demand studies as weather permits.. The TRUST has contracted Indiana University to perform studies related to the hyporheic flow into the river.
