The Power of Pairing
The City of Ames has been monitoring the South Skunk River on a weekly basis above and below its wastewater treatment system, the Water Pollution Control Facility, since 2003. There is a lot that could be done with this rich dataset, but we’ll look nitrate and total phosphorus from Jan 2011 to Sept 2020 to illustrate the value of long-term monitoring, and to demonstrate the power paired same-day observations for finding patterns amid the noise of weather variation. Pairing is an strategy that can boost the statistical power of smaller datasets as well.

Exploratory Data Analysis of the South Skunk River
Version 1.1 Prairie Rivers of Iowa is working with Story County and other partners to develop a plan for long-term stream monitoring to support environmental education and conservation projects. An essential step is exploring the data already being collected by the Iowa DNR to provide context for upstream monitoring sites.
