|MonitoringLocationDescriptionText||UMMP SITE #9 IS LOCATED ON A MID-CHANNEL BAR IMMEDIATELY DOWNSTREAM OF THE MANCHESTER STREET BRIDGE IN CONCORD. AT LOW FLOW, THE MID-CHANNEL BAR IS JUST VISIBLE AND CAUSES RIPPLES THAT DISTURB THIS FLATWATER REACH OF THE RIVER. THE SITE IS BOUNDED BY COMMERCIAL DEVELOPMENT, AGRICULTURAL FIELDS, AND TRANSPORTATION CORRIDORS (I-93 AND MANCHESTER STREET) WITH LIMITED RIPARIAN BUFFERS ON BOTH BANKS. OTHER THAN THE MID-CHANNEL BAR COMPOSED OF CUT GRANITE SLABS, THE RIVER BED IS DOMINATED BY FINE MATERIALS AND DEEP WATER THAT MAKES ACCESS BY A CANOE OR KAYAK NECESSARY.|
