An urban stream is a formerly natural waterway that flows through a heavily populated area . Often times, urban streams are low-lying points in the landscape that characterize catchment urbanization. Urban streams are often polluted by urban runoff and combined sewer outflows. Water scarcity makes flow management in the rehabilitation of urban streams problematic.
69-683: Eumemmerring Creek is an urban creek of the Port Phillip catchment, located in the southeastern Greater Melbourne region of the Australian east coast state of Victoria . It joins the Dandenong Creek (of which it can be considered a tributary ) to form the partly man-made Patterson River , which in turn drains into Beaumaris Bay . The creek's headwaters originate in the Dandenong Ranges as various small streams and springs from

Approximately 18 miles (29 km) south of Syracuse, the Tully Valley has unique hydro-geological features called mudboils . These mudboils are the cause of the excessive sedimentation of Onondaga Lake. The sediment enters Onondaga Creek, which flows north into
276-638: A greater presence of urban stream syndrome. Hydrology plays a key role in urban stream syndrome. As urbanization of these streams continue, there is in turn a decrease in the perviousness of the catchment to precipitation, which leads to a decrease in the infiltration and an increase in the surface runoff . This can cause problems during flood discharges. For example, flood discharges in urban catchments were at least 250% higher in urban catchments than in forested catchments in New York and Texas during similar storms. Many water managers treat USS by directly addressing

The ACJ achieved other successes. Between 1993 and 2006, the phosphorus discharges from Metro were decreased by 86%. Regarding contamination via CSOs, the ACJ required that by 2010 the county eliminate or capture for treatment 95% of
1863-442: The basis for discharge limits imposed on the county's Metro facility. In 1990, the U.S. Congress created the Onondaga Lake Management Conference (Public Law 101-596, section 401). It ordered the group to develop a comprehensive revitalization, conservation, and management plan for Onondaga Lake that recommends priority corrective actions and compliance schedules for its cleanup. The Conference also called for coordination of implementing
1932-585: The by-products of soda ash production. In 1907, the New York State Attorney General threatened the Solvay Process Company with legal action over the direct discharge of Solvay waste material into the lake. As Syracuse's population began to grow in the 20th century, a surplus of pollution hit the lake hard. This lake was so close to the city that the effects of people's sewage, exhaust fumes, and dumping of unnecessary products all caused
2001-412: The chemical pollution of Onondaga Lake. The surface water was found to be contaminated with mercury whereas the sediments are contaminated with polychlorinated biphenyls (PCBs), pesticides , creosotes , heavy metals ( lead , cobalt , and mercury ), polycyclic aromatic hydrocarbons (PAHs), chlorinated benzenes, and BTEX compounds ( benzene , ethylbenzene , toluene , xylene ). In Onondaga Lake
2070-505: The chlorinated benzenes are located in the southwest portion, in the form of a dense oily liquid that has settled into the sediments. These chemicals were intentionally dumped into the lake or unintentionally seeped in from upland toxic waste sites or from the Solvay wastebeds located at the southwest end of Onondaga Lake. Approximately 6 million pounds (2.7 kt) of salty wastes made up of chloride , sodium , and calcium were dumped into

The Solvay Process Company , incorporated in 1881, began drilling deep test holes in the area south of Syracuse in 1883. The company's main product was soda ash, integral to several industries. Eventually Solvay found halite deposits at a depth of 1,216 feet (371 m) below land surface in
2484-416: The dumping of sewage wastewater have led to excessive algae growth in the lake. When these excessive algae growths die, bacteria decompose the dead algae using large quantities of oxygen, which causes eutrophic and low-oxygen conditions. The low oxygen levels lead to the choking out of fish and plants, especially in the deeper areas of the lake. Eventually anoxic (oxygen-free) conditions set in parts of

Jesuit missionaries visiting the Syracuse region in the same time period were the first to report on salty brine springs around the southern end of what they called "Salt Lake," known today as Onondaga Lake. The brine springs were reported to have extended around much of
3657-573: The main cause can be attributed to urban and suburban development. This is because such land use has a domino effect that can be felt tens of kilometers away. Consistent decrease to ecological health of streams can be from many things, but most can be directly or indirectly attributed to human infrastructure and action. Urban streams tend to be "flashier" meaning they have more frequent and larger high flow events. Urban streams also suffer from chemical alterations due to pollutants and waste being uncleanly dumped back into rivers and lakes. An example of this
3726-446: The mid-1820s and the commercial production of salt brought an increase in settlement of the area. The lake's western shore became increasingly industrialized as the nineteenth century progressed. Onondaga Lake also became a popular resort area. By the late 19th century, its shoreline was dotted with hotels, restaurants, and amusement parks. The area was so popular that people traveled by railroad from as far as New York City to visit
