Question: Which one is located in Northern California Iron Mountain Mine or Spring Creek Dam?

Context paragraphs:
Split Yard Creek, Queensland: Split Yard Creek is a rural locality in the Somerset Region, Queensland, Australia.  It is home to the Wivenhoe Power Station located between the Splityard Creek Dam and the Wivenhoe Dam.  The Splityard Creek Dam borders the Wivenhoe-Somerset Road and there is a public carpark on the side of the road with access to the Splityard Creek Lookout.

Teviot Creek Dam: Teviot Creek Dam is a dam in North Queensland, Australia.  It is located on Teviot Creek, a tributary of the Isaac River, upstream of the Burton Gorge Dam.  Burton Coal Pty Ltd has a licence to take 1,500 ML/year from the dam.  The monthly supply reliability based on a relatively short period of record is thought to be 100%.  This does not account for the current critical period and the supply should not necessarily be relied on in future.  Teviot Creek Dam is owned and operated by RAG Australia Coal subsidiaries.

Iron Mountain Mine: Iron Mountain Mine, also known as the Richmond Mine at Iron Mountain, is a mine near Redding in Northern California, US.  Geologically classified as a "massive sulfide ore deposit", the site was mined for iron, silver, gold, copper, zinc and pyrite intermittently from the 1860s until 1963.  The mine is the source of extremely acidic mine drainage which also contains large amounts of zinc, copper and cadmium.  One of America's most toxic waste sites, it has been listed as a federal Superfund site since 1983.

Spring Creek Dam: 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.

Spring Creek Lodge Academy: Spring Creek Lodge Academy was a boarding school located in Thompson Falls, MT.  The school, formerly known as Spring Creek Community, was first opened in the 1970s by Nancy and Steve Cawdrey.  In 1996, the school and the property were purchased by Cameron Pullan and Dan Peart and given the name Spring Creek Lodge Academy.  For several years the school was associated with the Utah-based World Wide Association of Specialty Programs and Schools.  The school was opened as a place to address behavioral issues of young people from across the county as well help motivate students for success.  Its curriculum included a points and level system that rewarded compliance and punished noncompliance Extremely non-compliant individuals were often kept in solitary confinement // [§ \\ or transferred to a Mexican program known as High Impact, which was later closed by the Mexican Government due to allegations of child abuse.  At its peak enrollment, Spring Creek Lodge Academy housed over 500 students and employed about 200 individuals in various positions, making it the largest employer in Sanders County at that time.  The school closed in 2009 after an extreme drop in enrollment, several lawsuits, licensing issues, and oversight controversy.  In 2010 the Montana-based Academy for National Native Leadership purchased the former Spring Creek facility and began to offer college classes at the school.

Spring Creek Dam (New South Wales): Spring Creek Dam is a minor embankment dam across the Spring Creek upstream of Orange in the central western region of New South Wales, Australia.  The impounded reservoir is called the Spring Creek Reservoir.

Archaeal Richmond Mine acidophilic nanoorganisms: Archaeal Richmond Mine acidophilic nanoorganisms (ARMAN) were first discovered in an extremely acidic mine located in northern California (Richmond Mine at Iron Mountain) by Brett Baker in Jill Banfield's laboratory at the University of California Berkeley.  These novel groups of archaea named ARMAN-1, ARMAN-2 ("Candidatus" Micrarchaeum acidiphilum ARMAN-2 ), and ARMAN-3 were missed by previous PCR-based surveys of the mine community because the ARMANs have several mismatches with commonly used PCR primers for 16S rRNA genes.  Baker "et al." detected them in a later study using shotgun sequencing of the community.  The three groups were originally thought to represent three unique lineages deeply branched within the Euryarchaeota, a subgroup of the Archaea.  However, this has been revised, based on more complete archaeal genomic tree, that they belong to a super phylum named DPANN.  The ARMAN groups now comprise deeply divergent phyla named Micrarchaeota and Parvarchaeota.  Their 16S rRNA genes differ by as much as 17% between the three groups.  Prior to their discovery all of the Archaea shown to be associated with Iron Mountain belonged to the order Thermoplasmatales (e.g., "Ferroplasma acidarmanus").

Rifle Creek Dam: Rifle Creek Dam is owned by Mount Isa Mines.  With the completion of the East Leichhardt Dam in 1958, Rifle Creek Dam water was completely available for use by the mine.

Spring Creek Reservoir (California): The Spring Creek Reservoir is the artificial lake created by the construction of the Spring Creek Dam across Spring Creek in the Shasta-Trinity National Forest of Shasta County, California, adjacent to Keswick.

Meandu Creek Dam: The Tarong and Tarong North Power Stations source water from the Brisbane River catchment via a pipeline from Wivenhoe Dam.  Cooling tower blowdown water is either discharged directly to Tarong Energy's Meandu Creek Dam or supplied to the nearby Tarong Mine owned by Rio Tinto Coal Australia.  Excess water from the mine is discharged back to Meandu Creek Dam.  Releases from Meandu Creek Dam supply downstream irrigators on Meandu Creek.
