Streambank Restoration2026-01-20T12:00:40-06:00

As it stands today, streambank erosion is a major contributor of sediment and nutrients to the waters of the Basin. Restoring these streambanks to a healthy, functioning state is an important step needed to meet water quality goals. Streambank restoration has two main components: restoring & connecting and protecting & stabilizing. Here’s a little more on each:

Restore & Connect

One component of streambank restoration is to actively restore steep banks to a more natural shape. This normally involves shaping very steep, vertical streambanks to something that slopes more gradually.

By creating more gradual slopes and widening the stream channel, water from storms and snowmelts is directed to the center of the stream, where the banks are protected and less erosion will occur. The stream can also be connected to the floodplain, providing more time and space for water to flow, which reduces the impacts of flashiness and flooding.

Protect & Stabilize

The other component of streambank restoration involves protecting and stabilizing the streambank to prevent further erosion. This can be done with rip-rap or stream barbs (rock and tree trucks/stumps structures) and riparian plantings.

Rip-rap and barbs help to control the flow of water, while slowing it down before it reaches the more fragile streambank soil. Native plants like trees and grasses have roots that help to hold the soil in place and make it less prone to erosion. These structures also make for fantastic fish habitat!

What is the Issue?

When it rains or snow melts, that runoff water needs to go somewhere. It flows over the land, and into the ground, and moves throughout the watershed until it reaches a body of water. One of the first stops for that runoff is a natural water storage system like a wetland. Here water is slowed and stored until it is able to calmly enter a river, stream, or creek. In wet times of the year like spring, streams naturally take on extra water. That extra water goes into the stream’s floodplain, or the area surrounding the stream that can take on water.

Over time, this natural system has been disrupted. Wetlands and other runoff storage systems have been lost, streams have been ditched and dammed and no longer have connections to their floodplains, and rain and snowmelt events are becoming more frequent and intense. This has resulted in there being an excess amount of runoff water moving too quickly through watercourses. Fragile streambanks are unable to handle the extra water load and are eaten away by the turbulent water. This sends large amounts of nutrients and sediment downstream and into our lakes.

How the past impacts the present

To get the full picture of why streambank erosion is such a big issue today, we have to look back into the past. Historically (pre-1800s settlement), the Basin was home to many wetlands, forests, grasslands, and other ecosystems that played a crucial role in slowing and storing water on the land. Over the centuries, wetlands were drained and filled, forests cut down, grasslands plowed, and rivers dammed to make way for cities, farm fields, and industry.

Without these ecosystems, the watershed no longer has the capacity to deal with runoff water that comes from storms and snowmelt. This has resulted in there being to be too much water moving too quickly over the landscape. Check out the difference ~85 years made on the streambanks and delta of Duck Creek at Green Bay!

Practices We Use

At Fox-Wolf, we use a wide variety of practices to meet conservation goals with our projects. We call these Best Management Practices (BMPs). Depending on the need of the situation, different BMPs may be used. Here’s a look at a few we use for streambank restoration:

Rip-Rap

Rip-Rap are piles of large, rough rocks strategically placed on streambanks to prevent erosion. They work by being the first line of defense against fast moving water for fragile streambank soil. This helps to prevent streambank from eroding away and washing sediment and nutrients downstream.

Bank Regrading

Streams and creeks that have extreme erosion, or that were historically ditched, may require some reshaping of their banks. Using heavy equipment, we regrade streambanks to be closer to what they would be in its natural, healthy state.

Riparian Plantings

Riparian plantings, planting native vegetation on streambanks, can be a great solution to help stop and prevent streambank erosion. The roots of plants are very deep and help to hold soil in place. These plantings also provided food and habitat for wildlife.
