Click on each of the questions below to learn more about the Bear Creek boulder weirs.

What is a boulder weir?

What can boulder weirs do?

Where are boulder weirs located in the Bear Creek watershed?

How are they assembled?

At the Bear Creek National Research Watershed, new boulder weirs have been added to a previously straightened section of stream.

In this channelized area, the stream was beginning to widen after a stage of sever downcutting that may have lead to very high rates of erosion. It is known that boulder weirs produce many desireable effects in the aquatic environment. These boulder weirs will be studied to see how effective they are at reducing erosion when combined with riparian forest buffers.

We invite you to tour this site and look through the information. More information will be added as we continue to study these structures.
