Old River (California)

The Mokelumne River ( or ; Mokelumne, Miwok for "People of the Fish Net") is a 95-mile (153 km)-long river in northern California in the United States. The river flows west from a rugged portion of the central Sierra Nevada into the Central Valley and ultimately the Sacramento–San Joaquin River Delta, where it empties into the San Joaquin River-Stockton Deepwater Shipping Channel. Together with its main tributary, the Cosumnes River, the Mokelumne drains 2,143 square miles (5,550 km2) in parts of five California counties. Measured to its farthest source at the head of the North Fork, the river stretches for 157 miles (253 km). The river is colloquially divided into the Upper Mokelumne River, which stretches from the headwaters to Pardee Reservoir in the Sierra foothills, and the Lower Mokelumne River, which refers to the portion of the river below Camanche Dam. In its lower course, the Mokelumne is used heavily for irrigation and also provides water for the east San Francisco Bay Area through the Mokelumne Aqueduct. Several major tributaries of the river have been developed for the generation of hydroelectric power. The name is Plains Miwok and is constructed from moke, meaning fishnet, and -umne, a suffix meaning "people of". The town of Mokelumne Hill was named for the river in about 1850.

Franks Tract State Recreation Area (SRA) is a state park unit of California, United States, featuring a flooded area in the Sacramento–San Joaquin River Delta. It is accessible only by water. Franks Tract, and a smaller adjoining submerged property called "Little Franks Tract", are situated between the False River and Bethel Island. The recreation area is used primarily for fishing and waterfowl hunting, because of its exposure to frequent strong winds and fluctuating water levels. In times of high water, the entire site can be submerged except for portions of the old levees. The 3,523-acre (1,426 ha) park was established in 1959. It is managed from nearby Brannan Island State Recreation Area, 6 miles (9.7 km) to the northwest.

The United States Coast Guard Cutter Fir (WAGL/WLM 212) was the last lighthouse tender built specifically for the United States Lighthouse Service to resupply lighthouses and lightships, and to service buoys. Fir was built by the Moore Drydock Company in Oakland, California in 1939. On 22 March 1939, the U.S. Lighthouse Tender Fir was launched. She was steam driven with twin screws, 175 feet (53 m) in length, had a beam of 32 feet (9.8 m), drew 11 feet 3 inches (3.43 m) of water, and displaced 885 tons. Fir was fitted with a reinforced bow and stern, and an ice-belt at her water-line for icebreaking. She was built with classic lines and her spaces were lavishly appointed with mahogany, teak, and brass. The crew did intricate ropework throughout the ship. The cost to build Fir was approximately US$390,000. Fir's homeport was Seattle, Washington for all but one of her fifty one years of service when she was temporarily assigned to Long Beach, California when USCGC Walnut was decommissioned on 1 July 1982. On 1 July 1939 the United States Lighthouse Service became a part of the United States Coast Guard. On 1 October 1940 Fir was commissioned as the United States Coast Guard Cutter Fir (WAGL-212). With the onset of World War II Fir was assigned to the U.S. Department of the Navy and painted battleship grey. The following armament was installed for war service: M2 Browning machine guns, a 3-inch gun, and depth charges. Her wartime duties included picket duty, towing gunnery targets, and patrolling the Washington and Oregon coasts. In 1965, Fir was reclassified as a USCG coastal buoy tender (WLM). On 27 May 1988, after the decommissioning of USCGC Ingham, Fir gained the distinction as the U.S. Coast Guard's oldest commissioned cutter. In accordance with a Coast Guard custom, she displayed gold hull numbers on her bow and was designated as "Queen of the Fleet" on 30 May 1988. On 1 October 1990, the 200th anniversary year of the U.S. Coast Guard, Fir was honored again with the celebration on her 50th birthday. One year later, on 1 October 1991 Fir was decommissioned, and; on 27 April 1992 was designated a National Historic Landmark by the United States Secretary of the Interior. During her career, Fir was a multi-mission ship whose accomplishments mirrored the changing American maritime scene, and the needs of the U.S. Coast Guard for more than half a century. Fir's primary duties included resupplying coal, potable water, food, and other vital provisions; icebreaking, aids to navigation (ATON) maintenance, delivery and pick-up of U.S. Mail for lightships and lighthouses on the Washington and Oregon coasts. Fir tended the lightships at Umatilla Reef off La Push, Washington and Swiftsure Bank at the entrance of the Strait of Juan de Fuca Washington. In addition to servicing aids to navigation (ATON), Fir stood war duties during World War II, performed search and rescue missions, marine environmental protection, and law enforcement. For her last project, Fir was tasked to do what she was originally built for in 1939. In July 1991, Fir renovated and restored the Cape Flattery Lighthouse on Tatoosh Island at the entrance to the Strait of Juan de Fuca. There is successor cutter also named Fir, USCGC Fir (WLB-213), currently in active use by the Coast Guard, which is a 225-foot (69 m) cutter. She was launched in 2003 and is based in Astoria, Oregon.
