Question: Which Channel was completed first Bald Eagle and Spring Creek Navigation or Sacramento Deep Water Ship Channel ?

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.  The channel is about 30 feet (9 m) deep, 200 feet (61 m) wide and 43 miles (69 km) long.  It was completed by the United States Army Corps of Engineers in 1963. <SEP>  Opened for half its length in 1837, the remainder of the canal was not completed until 1848. 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.  Destroyed by flooding in 1865, it was not rebuilt; a paralleling railroad completed that year replaced it. <SEP> 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. <SEP> 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.
