Iowa Saturated Buffers

Iowa | Agriculture

Overview

ISG has worked with a number of Iowa partners to design and implement saturated buffers.


Opportunity

A number of watershed districts across Iowa have needed a drainage design partner to develop plans for saturated buffer projects. Below is a small snapshot of such projects.

Solution

Beckfield Saturated Buffer – Buena Vista County
Due to a large watershed and multiple outlets, two saturated buffers were installed along an existing drainage ditch. An iterative design process, the final installation addressed concerns of both tenants and landowners while treating an estimated 100 acres.

Fredricks Saturated Buffer – Buena Vista County
A recent installation, this saturated buffer treats approximately 20 acres along a recent Drainage District improvement project. Flow is currently monitored by Iowa State University and the USDA-ARS. Final design included input from researchers and IDALS to optimize the available buffer area. A comprehensive design resulted in quick installation.

B+S: NRCS Review – Buena Vista County
Due to the funding source, the B+S saturated buffer is currently under review by the Natural Resources Conservation Service. A close proximity to the Fredricks saturated buffer, Iowa State University in partnership with the USDA-ARS will monitor this site following construction.
