Ten Mile River

About

Ten Mile River, Rhode Island — 1636 Roger Williams, 1840s-1880s Milling, 2010s Roger Williams Paddle Trail 10-mi Providence. The river's hydrology is gentle by design. USGS streamgage 01109403 records an average flow of about 120 cubic feet per second, with a recorded historic flow near 108 CFS and a documented high around 860 CFS. Paddlers find the optimal window between roughly 50 and 300 CFS, a range that keeps the Class I water friendly through both the greenway reach and the tidal section below. The river runs in two recognizable stretches: Pawtucket to East Providence, a Class I urban greenway, and East Providence to the Seekonk River, a Class I tidal section that carries the current into salt water at the head of Narragansett Bay.

Long before gauges or trails, the Ten Mile River watershed was contested ground. It formed a borderland between the Wampanoag to the east and the Narragansett to the west, and its tidal reach provided productive shellfish beds and fishing grounds. That older world met the colonial one in 1636, when the Wampanoag showed Roger Williams and his followers a spring for drinking water near the river's banks—the moment the river enters the written record.

Industry followed settlement. The river's milling era ran through the 1840s to the 1880s, harnessing the same modest but persistent current that had drawn people to its banks in the first place. Around it, the broader watershed was logged from the 1830s through the 1920s, feeding the regional timber industry of 1850–1910 and the railroad expansion of 1860–1910. Local sawmills, logging drives, and downstream lumber operations were the major operators until the old-growth stands were exhausted around 1910, state forestry conservation began in 1915, and the establishment of state forests in the 1930s ended large-scale cutting.

The river also drew early scientific attention. USGS survey and hydrological work began in the 1870s, with gauging stations established in the following decades and state geological streamflow assessments carried into the early twentieth century—among the first comprehensive hydrological studies of the river. Later, state water pollution control studies in the mid-twentieth century and Clean Water Act assessments after 1972 addressed more than a century of logging, agricultural, and industrial impacts, with modern restoration and TMDL programs as the current outcome.

The present chapter is one of restoration and public access. In 2010, East Providence and the state of Rhode Island developed the Ten Mile River Greenway, combining a multi-use trail with river restoration to create a recreational corridor through the city's urban core. The Ten Mile River Watershed Council now stewards the river, hosting the annual Roger Williams Paddle Trail; one gathering was recorded as the fourth such event. Paddlers put in at Freedom Green, at the intersection of North Broadway and Roger Williams Avenue, at the north end of the park. A tributary of the Seekonk and part of the larger Blackstone River watershed, the Ten Mile today supports the economies of East Providence, Pawtucket, and Rumford—a small but enduring thread in Rhode Island's geography.
