Jabez Branch III Restoration Monitoring Data

Monitoring and Non-Tidal Assessment (MANTA) is working with partners to monitor a restoration project in the Jabez Branch III tributary of the Severn River in Anne Arundel County, Maryland to understand the effects of a regenerative stream conveyance (RSC) installation.

Four water quality parameters - dissolved oxygen, temperature, pH, and turbidity - have been monitored at three sites in the restoration reach, one site above the restoration, and two sites in mainstem Jabez Branch. Additionally, MANTA has collected biology, physical habitat, and iron flocculant data within the restoration reach and at the sites above, below, and adjacent to the restoration.

Explore the Eyes on Jabez website to access these data collected by MANTA and learn more about ongoing water quality monitoring and biological and habitat assessments related to the Jabez Branch III tributary restoration.
