An Overview of Rhode Island's Rivers and Lakes

Major Rivers, Lakes, Reservoirs, and Streams

Rhode Island's largest and most famous waterways include the Blackstone River, which flows through the northern part of the state and into Massachusetts, and the Pawtuxet River, notable for its historic significance and recreational use. The state also features lakes like Scituate Reservoir, which is the largest inland body of water, serving as a major water supply for Providence and nearby areas.

Water Sources and Origins

The rivers, lakes, and streams in Rhode Island are primarily fed by local sources such as precipitation, groundwater, and local runoff. While there are no distant mountains in the state, these water bodies rely on local water cycles rather than external sources from other states.

Types of Rivers and Lakes

Rhode Island's major perennial rivers include the Blackstone and Pawtuxet Rivers, which flow year-round. Exotic rivers and distributaries are less common due to the state's small size and geography. The state does not have volcanic or tectonic lakes but features fluvial lakes formed by river processes and anthropogenic lakes like Scituate Reservoir, created by damming the Scituate River.

Direction of Rivers and Lakes

Rivers in Rhode Island mostly flow east-west due to the state's geography and topography. Examples include the Pawcatuck River, which forms part of the state's border with Connecticut, and the Woonasquatucket River, flowing westward towards Providence.

Origin and Use of Lakes

Lakes in Rhode Island are primarily anthropogenic, created for water supply and flood control purposes. Scituate Reservoir, completed in 1926 by the Providence Water Supply Board, is the largest example. These lakes serve as critical water sources for both domestic use and agriculture.

Dams and Their Functions

There are numerous dams on Rhode Island's rivers and lakes, mainly used for water supply, flood control, and hydroelectric power generation. Scituate Reservoir's dams, for instance, manage water levels to meet regional demand while preventing floods downstream.

Recreation on Water Bodies

Rhode Island's water bodies support various recreational activities such as fishing, boating, and kayaking. The Pawtuxet River and Scituate Reservoir are popular destinations for fishing enthusiasts, while Narragansett Bay offers opportunities for sailing and boating.

Waterways Supporting Agriculture

Scituate Reservoir plays a crucial role in supporting Rhode Island's agriculture by providing irrigation water for farms in the region. This reservoir ensures consistent water supply, particularly during dry seasons, essential for maintaining crop yields.
