Title: Lake Merritt
Content:  Lake Merritt is a large tidal lagoon in the center of Oakland, California, just east of Downtown. It is surrounded by parkland and city neighborhoods. It is historically significant as the United States' first official wildlife refuge, designated in 1870, and has been listed as a National Historic Landmark since 1963, and on the National Register of Historic Places since 1966. The lake features grassy shores, several artificial islands intended as bird refuges and an interpretive center called the Rotary Nature Center at Lakeside Park. It has a boating center where sailboats, canoes and rowboats can be rented and classes are held. There is a fairy-tale themed amusement park called Children's Fairyland. The Gardens at Lake Merritt is also inside Lakeside Park. It is a 7.5 acre garden which contains seven themed gardens (Japanese, Mediterranean, Bonsai and more) as well as community garden plots for growing food. The Gardens host the Autumn Lights Festival annually in late October, bringing over 100 artists to the garden with fabulous illuminated and digital art. A popular walking and jogging path runs along its Lake perimeter. The circumference of the lake is 3.4 mi and its area is 155 acre.

Content:  Because storm drains in downtown Oakland and surrounding areas drain directly into the lake, trash and nutrient pollution have become the largest problems affecting Lake Merritt. Increased levels of chemicals like nitrogen and phosphorus cause algae blooms, which deplete the water of oxygen. Aeration fountains, funded by donations, have been installed to help with this problem. "Water quality in an area of about one acre around each unit is improved by the transfer of oxygen from the air, and by mixing the top and bottom layers of the Lake." A proposed aeration system was never approved by the City of Oakland. Trash removal is coordinated by the non-profit Lake 
Title: Lake Oakland (Michigan)
Content:  Oakland Lake is a 255-acre lake located in central Oakland County in both Waterford Township and Independence Township. There are several basins in the lake, reaching 25 feet, 27 feet, and the deepest being 64 feet, with all three basins having relatively steep side slopes. There are a number of shallow bays on the lake that are less than five-feet deep and several small islands. Originally called Pond Lake, Oakland Lake is located on the upper reaches ofthe Clinton River watershed. The Clinton River enters Oakland Lake on the west end through a short, wide connection to Woodhull Lake immediately upstream. The Clinton River exits on the southeast end where there are two dams that regulate water level. Both Oakland and Woodhull lakes have a legal established lake level elevation of 957.43. A short distance downstream of Oakland Lake, the Clinton River enters into Schoolhouse Lake and Loon Lake. Near the central portion of Oakland Lake and to the south, a short, shallow connection leads to Leggets Lake, which is a small (25 acres), shallow (10 feet) lake.

It was regarded as ideal for sewage because of its chemical contents, which have high acidities that cause it to decompose human feces at very high rates. Sixty miles of brick and wood channeling sent the broken-down sewage to the bottom of the lake to then be eaten by bottom feeders. The stench at the lake during the decomposition of the sewage was a problem for Oaklanders on the west shore and residents of Clinton and San Antonio villages on the east. Dr. Samuel Merritt, a mayor of Oakland who 
Title: Merrill Lake (Merrill Creek)
Content:  Merrill Lake is a lake in the Moira River and Lake Ontario drainage basins that straddles the border between the Cashel portion of Tudor and Cashel, Hastings County and Addington Highlands, Lennox and Addington County in Ontario, Canada. The lake is about 4.3 km long and 1.3 km wide and lies at an elevation of 338 m about 12 km northeast of the community of Gunter and 19 km northwest of the community of Cloyne. The northwest end of the lake lies in Tudor and Cashel, Hastings County, the rest in Addington Highlands, Lennox and Addington County. The primary inflow is Merrill Creek from Todd Lakes at the north of the east bay, and there are six unnamed creek secondary inflows: one at the northwest, three at the north and two at the north of the east bay. Merrill Creek is also the primary outflow, at the southeast towards Little Merrill Lake. It flows via Partridge Creek, the Skootamatta River and the Moira River into the Bay of Quinte on Lake Ontario at Belleville.
Title: Lake Merritt
Content:  In addition to nutrient pollution, more toxic agents have drained into the lake from time to time. In 1998, about 20 gallons of diesel fuel leaked into the lake following a "freakish accident" in the basement of the Caltrans building in the 100 block of Grand Avenue. On June 27, 2011, the Oakland Fire Department and California Department of Fish and Game responded to a diesel fuel spill that covered five acres of the northwest side of the lake. "Because the storm drain connects to other storm drains in the city, and due to the heavy rain, Oakland Fire Battalion Chief Darin White said firefighters were having difficulty finding where the spill originated."

Content:  of fresh and salt water draining in and out from the Oakland Harbor at the San Francisco Bay and one of Oakland's most notable features. It was designated the United States' first official wildlife refuge in 1870. Originally a marsh-lined wildlife haven, Lake Merritt was dredged and bordered with parks from the 1890s to the 1910s. Despite this reduction in habitat, Oakland is home to a number of rare and endangered species, many of which are localized to serpentine soils and bedrock. Lake Merritt is surrounded by residential and business districts, including downtown and Grand Lake.  The city of Piedmont, incorporated in Oakland's central foothills after the 1906 earthquake, is a small independent city surrounded by the city of Oakland.
