WMA WATER WITHDRAWAL AND NPDES WASTEWATER DISCHARGE SUMMARY


Based on available information there are no WMA regulated withdrawals or NPDES discharges along this segment of the Segreganset River.

USE ASSESSMENT

AQUATIC LIFE

Habitat and Flow

No flow (0.0 cfs) was reported by USGS at their gage on the Segreganset River between 8 July and 15 September 1999 and 23 to 29 July and 1 August to 16 September 2002 (Socolow et al. 2000 and 2003). Furthermore, water can be taken from the Segreganset River at the Somerset Water Department’s intake near the Segreganset River Dam.
The Aquatic Life Use is assessed as impaired in this segment of the Segreganset River because of the low and no flow conditions that frequently occur during the summer and fall months of the year.

RECOMMENDATIONS

Conduct monitoring (biological, habitat and water quality) to evaluate impacts to the Segreganset River from potential sources of pollution (e.g., golf course, developments, water withdrawals), document impairments caused by low flow conditions, and better assess the status of the Aquatic Life Use.


Conduct bacteria sampling to evaluate effectiveness of nonpoint source pollution control activities and to assess the status of the Primary and Secondary Contact Recreational uses.
Continue to monitor compliance with WMA registration/permit limits and other special conditions of the permits.
