The Waterscapes Ecosystem Team now has recommendations for revisions to your cooperative’s Waterscapes Indicators. These changes are now open for comment until Jan 15th. You can either comment at the bottom of this post or email me directly (rua@southatlanticlcc.org).

Here are the proposed changes to the Waterscapes Indicators:

Index of fish passage Index of fresh and saltwater connectivity

Reason for selection: Barriers to connectivity between rivers/streams and the ocean can strongly impact diadromous fish and alter natural movement of sediments, are easy to monitor and model, and are widely used and understood by diverse partners.

Proposed change: Estimating the index of fish passage across the entire geography was not practical at this time. This new indicator provides a simple metric for looking at connectivity between fresh and saltwater using the number of downstream dams within each HUC12 subwatershed in the LCC.

Number of dams mimicking natural flow Index of resident fish connectivity

Reason for selection: Barriers to connectivity within rivers/streams can strongly impact aquatic diversity and alter natural movement of sediments, are easy to monitor and model, and are widely used and understood by diverse partners.

Proposed change: Estimating the number of dams mimicking natural flow across the entire geography was not practical at this time. This new indicator maintains consistency with the methods for assessing connectivity alteration for resident fish in the Southeast Aquatic Connectivity Assessment Project (SEACAP). It uses the numbers of upstream and downstream dams and roads crossings within the local watershed to calculate connectivity.
