The Los Angeles Aqueduct system, comprising the Los Angeles Aqueduct and the Second Los Angeles Aqueduct, is a water conveyance system, built and operated by the Los Angeles Department of Water and Power. The Owens Valley aqueduct was designed and built by the city's water department, at the time named The Bureau of Los Angeles Aqueduct, under the supervision of the department's Chief Engineer William Mulholland. The system delivers water from the Owens River in the Eastern Sierra Nevada Mountains to Los Angeles.
The Medina Dam is a hollow-masonry type dam built in 1911 and 1912 by the Medina Irrigation Company in what became Mico, Texas, USA. Medina Lake extends north of it in northeastern Medina County and southeastern Bandera County. The dam and irrigation project was designed and financed by Dr. Frederick Stark Pearson, an American engineer, with extensive British financial backing. The construction took over 1500 men two years to build while working 24 hours a day. They were mostly skilled Mexican workers with experience building other dams for Pearson. They received two dollars for a day's work, which were good wages for the time. Pearson's Medina Irrigation Company (MICO) built a camp to house the workers and their families; the company town was first called MICO after its acronym. The community is now known as Mico, Texas.
The Ohio and Erie Canal was a canal constructed during the 1820s and early 1830s in Ohio. It connected Akron with the Cuyahoga River near its outlet on Lake Erie in Cleveland, and a few years later, with the Ohio River near Portsmouth. It also had connections to other canal systems in Pennsylvania.
San Antonio Missions National Historical Park is a National Historical Park and part of a UNESCO World Heritage Site preserving four of the five Spanish frontier missions in San Antonio, Texas, USA.

Today, the structure is one of four missions that comprise San Antonio Missions National Historical Park.
The Croton Aqueduct or Old Croton Aqueduct was a large and complex water distribution system constructed for New York City between 1837 and 1842. The great aqueducts, which were among the first in the United States, carried water by gravity 41 miles (66 km) from the Croton River in Westchester County to reservoirs in Manhattan. It was built because local water resources had become polluted and inadequate for the growing population of the city. Although the aqueduct was largely superseded by the New Croton Aqueduct, which was built in 1890, the Old Croton Aqueduct remained in service until 1955.
Mission San Juan Capistrano was founded in 1731 by Spanish Catholics of the Franciscan Order, on the eastern banks of the San Antonio River in present-day San Antonio, Texas. The new settlement was named for a 15th-century theologian and warrior priest who resided in the Abruzzo region of Italy. The mission San Juan was named after Saint John of Capestrano.
El Rancho de las Golondrinas, a historic rancho and now a living history museum, is strategically located on what was once the Camino Real, the Royal Road that extended from Mexico City to Santa Fe. The ranch provided goods for trade and was a place where the caravans that plied the road would stop on their journey coming from or going to Santa Fe. It was a paraje, an official rest stop for travelers, and was even mentioned by the great colonial military leader and governor, Don Juan Bautista de Anza, when he stopped here with his expeditionary force in 1780.
Franciscan Friars established Mission Nuestra Señora de la Purísima Concepción de Acuña in 1711 as Nuestra Señora de la Purísima Concepción de los Hainais in East Texas. The mission was by the Domingo Ramón-St. Denis expedition and was originally meant to be a base for converting the Hasinai to Catholicism and teaching them what they needed to know to become Spanish citizens. The friars moved the mission in 1731 to San Antonio. After its relocation most of the people in the mission were Pajalats who spoke a Coahuiltecan language. Catholic Mass is still held at the mission every Sunday.
The Lowell Power Canal System is the largest power canal system in the United States, at 5.6 miles in length. It is operating through six major canals on two levels, controlled by numerous gates. The system was begun in the 1790s, beginning its life as a transportation canal called the Pawtucket Canal, which was constructed to get logs from New Hampshire down the Merrimack River to shipbuilding centers at Newburyport, Massachusetts, bypassing the 30-plus-foot drop of the Pawtucket Falls.

Architecture in the American city of San Antonio, Texas comes from a wide variety of sources, but many of the city's buildings reflect Texas' Spanish and Mexican roots; with some influence from French builders, among others. Relatively rapid economic growth since the mid twentieth century has led to a fairly wide variety of contemporary architectural buildings.
Presidio de Béxar was a Spanish fort built near the San Antonio River, located in what is now San Antonio, Texas, in the United States. It was designed for protection of the mission San Antonio de Valero and the Villa de Béjar. The Presidio de Béxar was founded on May 5, 1718 by Spanish colonial official Martín de Alarcón and his party of thirty-five soldiers. The Villa de Béjar is known for being the first Spanish settlement of San Antonio and consisted of the families of the Presidio Soldiers and those of the prior expeditions. It also served to secure Spain's claim to the region against possible encroachment from other European powers.
The Conservation Society of San Antonio is located in the Bexar County city of San Antonio in the U.S. state of Texas. Founding members were Emily Edwards, who became the organization's first president, and Rena Maverick Green. The organization was formed on March 22, 1924, and officially incorporated on July 8, 1925. The Society is currently headquartered in the Anton Wulff House, which they saved from destruction in 1974. The home was built 1869–1870 by German immigrant Anton Wulff, who became the city's first Park Commissioner.
Acequia Park is located in the city of San Antonio in the U.S. state of Texas. There are picnic tables and restrooms, but alcohol is not allowed in the park. The origins of the park date back to Spanish missionaries, who worked with mission Indians to create a water system sourced by the San Antonio River. The San Antonio Conservation Society (SACS) purchased much of this acreage in 1957 to preserve the area's environment. Because the San Antonio River Authority planned to reconfigure the river channel, SACS joined local land owners in filing a successful water rights and water flow lawsuit against the Authority. In 1975, SACS deeded the property to the City of San Antonio with the stipulation that it be used as a public park.
Acequia Madre de Valero is an 18th-century agricultural irrigation canal built by the Spanish and located in the Bexar County city of San Antonio in the U.S. state of Texas. When Martín de Alarcón founded San Antonio for Spain by establishing San Antonio de Valero Mission in 1718, Franciscan priest Antonio de Olivares and the Payaya and Pastia peoples, dug Acequia Madre de Valero by hand. It was vital to the missions to be able to divert and control water from the San Antonio River, in order to grow crops and to supply water to the people in the area. This particular acequia was the beginning of a much wider irrigation system. Acequia Madre de Valero ran from the area currently known as Brackenridge Park southward to what is now Hemisfair and South Alamo Street. Part of it that is not viewable by the public runs beneath the Menger Hotel. The acequia was restored in 1968 and that same year was designated a Recorded Texas Historic Landmark.
