Harmony Forge Mansion is a historic home and property located at Boggs Township, Centre County, Pennsylvania.
 It was built between 1810 and 1820 by Joseph Miles, and is a 2 1/2 story, 5-bay stone building, with a 2-story stone kitchen wing.
 It measures 44 feet, 6 inches, by 40 feet.
 Also on the property are two barns, a twos-story frame dwelling, and the 2,000 feet of earthworks ruins of the Bald Eagle and Spring Creek Navigation Canal, built about 1847.
 The property includes the remains of Locks #4 and #5 of this canal.
 The Harmony Forge, built about 1795, and the workers houses are no longer extant.
Spring Creek Debris Dam is an earthfill dam on Spring Creek, a tributary of the Sacramento River, in Shasta County in the U.S. state of California.
 Completed in 1963, the dam, maintained by the U.S. Bureau of Reclamation, serves primarily to collect severe acid mine drainage stemming from the Iron Mountain Mine.
 The dam forms the Spring Creek Reservoir, less than 1 mi long.
 Spring Creek and South Fork Spring Creek flow into the reservoir from a 16 sqmi watershed.
 The dam is directly upstream from the city of Keswick, California and the Keswick Reservoir.
A spring creek is a type of free flowing river whose name derives from its origin: an underground spring or set of springs which produces sufficient water to consistently feed a unique river.
 The water flowing in a spring creek may additionally be fed by snow pack or rain run-off, as in most traditional free-flowing rivers, but often the entire water source for a spring creek is an aquifer or other underground water source.
 For this reason, spring creeks are often filled with very pure, clean water and also demonstrate water flows that are smooth, consistent, and unwavering throughout the seasons of the year - unlike rivers filled with run-off or spring and summer melt-off from snow pack, whose water flows, water clarity, and water conditions often vary highly over the course of the year.
 In addition, water temperatures in spring creeks tend to vary less throughout the seasons of the year than traditional creeks and rivers because they are fed by underground water sources.
 Because of the depths of these water sources, spring creeks often emerge from their source or headwaters very cold and stay that way over the length of their runs.
 In addition, due to the consistent water flows and the fact that spring creek water is "pushed" by the force of pressure from the source rather than "pulled" by the force of gravity downhill, spring creeks can flow through very flat sections of land with minimal depths over grades that might not sustain run-off creeks and rivers.
 In these low-grade or flat sections of spring creeks, water flows can appear almost laminar with the surface of the creek appearing to be nearly flat and without the prominent riffles and surface disturbances caused by more rough or uneven surface bottoms found below free-stone run-off creeks and rivers surfaces.
Bald Eagle is an unincorporated populated place in Blair County, Pennsylvania, United States.
 It is located in the Bald Eagle Valley at the foot of the Bald Eagle Mountain ridge, along the Big Fill Run near its confluence with the headwaters of the Bald Eagle Creek tributary of the Little Juniata River.
 Originally a stop on the Pennsylvania Railroad Tyrone Division, it is now exit 52 off of Interstate 99, and was the former northern terminus of the unfinished highway.
 The Bald Eagle post office zip code is 16686.
The Bald and Golden Eagle Protection Act (16 U.S.C. 668-668d) is a United States federal statute that protects two species of eagle.
 The bald eagle was chosen as a national emblem of the United States by the Continental Congress of 1782 and was given legal protection by the Bald Eagle Protection Act of 1940.
 This act was expanded to include the golden eagle in 1962.
 Since the original Act, the Bald and Golden Eagle Protection Act has been amended several times.
 It currently prohibits anyone, without a permit issued by the Secretary of the Interior, from "taking" bald eagles. Taking is described to include their parts, nests, or eggs, molesting or disturbing the birds.
 The Act provides criminal penalties for persons who "take, possess, sell, purchase, barter, offer to sell, purchase or barter, transport, export or import, at any time or any manner, any bald eagle ... [or any golden eagle], alive or dead, or any part, nest, or egg thereof."
The Sacramento Deep Water Ship Channel (also known as Sacramento River Deep Water Ship Channel or SRDWSC) is a canal from the Port of Sacramento in West Sacramento, California to the Sacramento River, which flows into San Francisco Bay.
 It was completed by the United States Army Corps of Engineers in 1963.
 The channel is about 30 feet (9 m) deep, 200 feet (61 m) wide and 43 miles (69 km) long.
The Bald Eagle and Spring Creek Navigation Company was a canal company in central Pennsylvania intended to link the iron industry of Bellefonte, Pennsylvania, with the Pennsylvania canal system.
 Opened for half its length in 1837, the remainder of the canal was not completed until 1848.
 Destroyed by flooding in 1865, it was not rebuilt; a paralleling railroad completed that year replaced it.
The Nittany Valley is an eroded anticlinal valley in the central portion of Centre County, Pennsylvania in the United States.
 It is separated from the Bald Eagle Valley by Bald Eagle Mountain and from Penns Valley by Mount Nittany.
 The valley is closed to the north by a high plateau that joins these two mountain ridges, but is open to the south at the southern terminus of Mount Nittany.
 The valley drains to the Bald Eagle Creek through water gaps in Bald Eagle Mountain formed by Spring Creek, and Fishing Creek, along with smaller streams running through Curtain Gap and Howard Gap.
 The Northwest side of the valley between the Bald Eagle Mountain ridge and the lower Sand Ridge is also known as the "Little Nittany Valley".
Bald Eagle State Park is a 5900 acre Pennsylvania state park in Howard, Liberty, and Marion townships in Centre County, Pennsylvania in the United States.
 The park includes the Foster Joseph Sayers Reservoir, formed by damming Bald Eagle Creek and other smaller streams and covering 1730 acre .
 Bald Eagle State Park is at the meeting point of two distinct geologic features.
 The Allegheny Plateau is to the north and the Ridge and Valley area of Pennsylvania is to the south.
 The park is in the Bald Eagle Valley off Pennsylvania Route 150 in Howard, between Milesburg and Lock Haven.
Challenger is a non-releasable bald eagle in the care of the non-profit American Eagle Foundation.
 He is the first bald eagle in history trained to free fly into major sporting events during the national anthem.
