Шаблон:Infobox river The Clyde River is a tributary of Lake Memphremagog, over Шаблон:Convert long, in northern Vermont in the United States. It is the easternmost of the four major rivers in Orleans County. It is the most powerful of the four within Orleans County, powering several turbines at damsites. It is part of the Northern Forest Canoe Trail.

It was named by one of the early surveyors from his partiality to a river of the same name in Scotland.

The Route 105/114 junction to Clyde Road section of Clyde River in Vermont is Шаблон:Convert long and is rated by American Whitewater as a class I-III section.

Geography

It drains the water from about Шаблон:Convert. With the exception of three miles (5 km) of rapids near its mouth, this is a very sluggish stream, passing through in its course, several natural ponds of considerable size. Even during spring high water, there is barely a perceptible current.

Course

The river has its source in Spectacle Pond (length: Шаблон:Convert; altitude: Шаблон:Convert) in Brighton. The Southern part of Spectacle Pond is part of Brighton State Park. Spectacle Pond is actually a kettle. It is only Шаблон:Convert deep with a thick bottom of muck.

From the mouth of Spectacle Pond, the Clyde river flows on Шаблон:Convert as follows:

Higher course of the river (segment of Шаблон:Convert)

• Шаблон:Convert toward Northwest up to East bank of Island Pond;
• Шаблон:Convert toward Northwest crossing the Island Pond (length: Шаблон:Convert; altitude: Шаблон:Convert) toward Island Pond up to the mouth of the pond
• Шаблон:Convert toward the Southwest crossing the city of Island Pond et passing at South of Bluff Mountain, up to the confluence of Pherrins River (coming from North).

Pherrins River which is the main tributary of Clyde River, empties into the Clyde River from the north at Шаблон:Convert below the outlet, frequently rises quite suddenly, swelling the waters of the latter so as to reverse its current and cause it to back up into Island Pond with great force for ten hours or more, until the pond is full, or the water subsides below, when it will again change and rush out.

Intermediary course of the river (segment of Шаблон:Convert)

From the mouth of Pherrins River, the Clyde River flow as follow:

• Шаблон:Convert toward Southwest, up to Oswegatchie Pond (coming from South);
• Шаблон:Convert toward Northwest, snaking between Rosebrook Hill (located on South side) and Dollif Mountain (located on North side) up to the discharge of Mud Pounds (coming from North);
• Шаблон:Convert toward Northwest, up to the limit of Charleston;
• Шаблон:Convert toward Northwest in Charleston, up to the discharge (coming from North-East) of a lake;
• Шаблон:Convert toward Northwest, un to Lang Brook (coming from North);
• Шаблон:Convert toward North-West by passing an island at the end of this segment, up to Back Brook (coming from the South);
• Шаблон:Convert toward Northwest, up to Mad Brook (coming from South);
• Шаблон:Convert toward Northwest, passing at Northeast of Deer Hill (altitude of summit: Шаблон:Convert), up to the discharge (coming from North) of Lake Echo (altitude: Шаблон:Convert) and from Lake Seymour (altitude: Шаблон:Convert); the confluence of this discharge is located at the South of East Charleston village;
• Шаблон:Convert toward Northwest, splitting in two for bypassing an island (length: Шаблон:Convert), then snaking up to the discharge (coming from South) of Toad Pond;
• Шаблон:Convert (or Шаблон:Convert in direct line) toward Northwest, up to South bank of Pensionner Pond.

Lower course of the river (segment of Шаблон:Convert)

• Шаблон:Convert Northward crossing Pensioner Pond (altitude: Шаблон:Convert) up to the mouth where the lake is narrowing and curving to Northwest;
• Шаблон:Convert Northward up to the South bank of Charleston Pond;
• Шаблон:Convert Northward up to the dam at the mouth of Charleston Pond (altitude: Шаблон:Convert);
• Шаблон:Convert to Northwest up to South bank of a lake;
• Шаблон:Convert to Northwest up to the confluence of the lake which is linked to Lake Salem by a strait of Шаблон:Convert;
• Шаблон:Convert to Northwest crossing Lake Salem (altitude: Шаблон:Convert) up to the mouth;
• Шаблон:Convert Westward forming a curve to North, crossing the Interstate 91 and snaking up to the dam located at the Northeast end of Clyde Pond #1;
• Шаблон:Convert to Southwest, crossing Clyde Pond #1 (altitude: Шаблон:Convert), up to the dam on West bank of the pond;
• Шаблон:Convert to West up crossing the city of Newport up to the confluence at the South bank of the Lake Memphremagog (altitude: Шаблон:Convert).

Charleston

The Clyde River is the largest in Charleston. It runs nearly through the center of the town. Some falls of importance are found on the stream, especially the Great Falls in the western part of the town, where the descent is more than Шаблон:Convert in Шаблон:Convert; but its current is generally slow.

Derby

The Clyde River forms the principal water-course, flowing through the town from east to west.

After exiting from Clyde Pond #1, it proceeds westward. It empties into Lake Salem from the south. It exits the northwest corner of this lake. It is then joined by an unnamed brook from Derby Pond from the north. It then empties into Clyde Pond #2 from the northeast. It exits this Pond west and into south Lake Memphremagog from the north. The mouth is just east of where US 5/Vermont 105 crosses Lake Memphremagog.

Natural history

Beavers populate the countryside and sometimes undercut the streamside silver maple, toppling them into the water and creating logjams.

The river winds through farm country, with silver maple and alder dominating the shoreline. Northern white cedar, an occasional willow, and a variety of shrubs line the Шаблон:Convert wide waterway, and vegetation dips right into the water.Шаблон:Citation needed

History

Toponymy

The term "Clyde" is a popular first name with English origin. This term is also used as surname.

This toponym was officialized on October 29, 1980 at Geographic Names Information System (GNIS) of US federal government.

Dams

In the early 19th century a mill dam constructed at Arnolds Falls. In 1883 a dam was constructed at the outlet to Lake Memphremagog. In 1918 the Newport Dam (Clyde Pond #2) was constructed. This dam was also known as Prouty Dam (after Governor Prouty). It was Шаблон:Convert long. This was also known as the Clyde Pond dam.

The Echo Lake dam is not used for hydroelectric power. Construction was completed in 1922. It has a normal surface area of Шаблон:Convert. It is owned by Great Bay Hydro Corporation. The dam is concrete. The core is homogeneous concrete. The foundation is rock. The height is Шаблон:Convert. Maximum discharge is Шаблон:Convert per second. Its capacity is Шаблон:Convert. Normal storage is Шаблон:Convert. It drains an area of Шаблон:Convert.

In 1928 a dam was constructed at West Charleston. In 1929 a dam was built at Pensioner's Pond.

In 1957 #11 Dam was constructed. It was located Шаблон:Convert below the current hydro generation station off Clyde Street. In 1994 the #11 Dam was breached. In 1996 the #11 Dam was removed. In 2007 a fish (salmon) passage was built at the Newport Dam. Salmon fishing in Lake Memphremagog and the Clyde nearly stopped when the dam was constructed. It has improved since the dam's removal. The State of Vermont stocks the river with 30,000 salmon annually. 6,000 perish immediately from predators. Of those that make the journey to Lake Memphremagog, 18,000 return to spawn. The remainder assumed to be caught by fishermen.

Lists

Tributaries

The following dams are on tributaries (watershed) that feed into the Clyde, and not the Clyde itself:

Lake Seymour is on a tributary which drains into Echo Lake, which in turn drains into the Clyde. It is not used for hydroelectric power. Construction of the original dam was completed in 1928. The lake has a normal surface area of Шаблон:Convert. It is owned by Great Bay Hydro Corporation. This dam is stone, and concrete. The core is concrete. The foundation is soil. Its height is Шаблон:Convert by Шаблон:Convert long. Maximum discharge is Шаблон:Convert per second. The capacity is Шаблон:Convert. Normal storage is Шаблон:Convert. It drains an area of Шаблон:Convert.
