Water Sampling in the Upper Wapsi

Published / by Megan Buckingham

Elaine Hughes prepares to draw samples from Buffalo Creek near Quasqueton.

A couple of times a month, volunteers collect water samples from streams, creeks and the Wapsipinicon River. Samples are sent to Coe College, where they are tested for nitrates, phosphorous, chlorine, sulfate and total suspended solids.

Monitoring is a critical component of improving water quality. As the Upper Wapsi WMA sets improvement goals, the data collected can help them identify the most critical problems in the watershed and prioritize effective solutions.

The Daily Erosion Project

The Daily Erosion Project (DEP) estimates precipitation, runoff, sheet and rill erosion, and hillslope delivery in near real time, on over 2000 watersheds in the Midwest (Figure 1). It does this by running the Water Erosion Prediction Project (WEPP) model with a combination of remotely-sensed precipitation weather stations, remotely-sensed crop and residue cover, remotely-sensed topography, and soils databases.

It is an update and expansion to the Iowa Daily Erosion Project (Cruse et al., 2006) that is designed to further investigate large scale erosion dynamics while maintaining hillslope level input resolution. The DEP has a climate database extending from 2007  to the present day, enabling investigation of single event and single year runoff and soil erosion dynamics over a large time range and spatial extent.

The Upper Wapsi Watershed Management Authority

Published / by Ross Evelsizer

The Upper Wapsi Watershed Management Authority is currently signing up entities that would like to join. Watershed Management Authorities form under a 28E agreement authorized by Iowa code. Entities eligible to join a WMA are County boards of supervisors, Soil and Water Conservation Districts, and communities that lie on or within the watershed boundary. There is no membership cost to the member entities. For more information about WMA’s visit the Iowa DNR website regarding Watershed Management Authorities
