Lakes, Rivers, and Streams
Many places rely on snowmelt to fill the lakes, rivers, and streams that help keep drinking water reservoirs full and provide water to irrigate crops.
lakes - substantial inland bodies of standing water.
landfill - disposal area where garbage is piled up and eventually covered with dirt and topsoil.
LAKES AND WATER LIFE
Acid rain has a terrible effect on water life. Even if the acid rain does not fall straight into the lake, for example, it may enter from rivers and streams.
Lakes and reservoirs that freeze over and normally go through two stratifications and two mixing cycles a year.

Many lakes are subject to natural acid runoff from acid soils, and this can be triggered by particular rainfall patterns that concentrate the acid. An acid lake with newly-dead fish is not necessarily evidence of severe air-pollution.

the science that studies the remains of plants and animals in such habitats as lakes, bogs, and marshes. Diatom frustules, pollen grains, insects, and other animal remains are preserved in these areas of poor decomposition.
Reservoirs and lakes which contain moderate quantities of nutrients and are moderately productive in terms of aquatic animal and plant life.
metabolism (meh-TAB-uh-LIZ-um).
Many forests, streams, and lakes-and the creatures that live in them-are still suffering damage from acid rain. Even though the problem of acid rain has been reduced, sulfur and nitrogen pollution levels must be brought down further.
hydrosphere The aqueous envelope of the Earth, including the oceans, freshwater lakes, rivers, saline lakes and inland seas, soil moisture and vadose water, groundwaters, and atmospheric vapor.
Freshwater Conservation The concerted effort to protect fresh water ecosystems that include lakes and rivers. Bodies of fresh water are a valuable resource as they water our crops, provide fish, power factories and carry goods to market.
Surrounding the Great Lakes in both the U.S. and Canada is the white pine-red pine association, which is included in both the northern coniferous forest and temperate deciduous forest biomes (northern hardwoods association) by various authors.
rivers, streams, lakes and pools, springs), including their littoral zones. Also includes dune slack pools.
Photic Zone - In the ocean (or in lakes) this is the area near the surface with enough light to support photosynthesis. In this zone, both the chemical and biological activity can be enhanced by penetrating solar radiation.
receiving waters Bodies of water that receive runoff or wastewater discharges, such as streams, rivers, and lakes. recharge Process by which precipitation or applied water seeps or percolates into the groundwater system.

Glacial lakes have been rapidly forming on the surface of the debris-covered glaciers in this region during the last few decades.
In response to just such a problem occurring in Lakes Ontario and Erie in the late 1960s and early 1970s, the U.S. and Canada signed the Great Lakes Water Quality Agreement in 1972.
Source water protection: Voluntary action taken to prevent the pollution of drinking water sources, including groundwater, lakes, rivers, and streams.

Eutrophication - Eutrophication is a process whereby water bodies, such as lakes, estuaries, or slow-moving streams receive excess nutrients that stimulate excessive plant growth (algae, periphyton attached algae, and nuisance plants weeds).
The continuous process of surface water (puddles, lakes, oceans) evaporating from the sun?s heat to become water vapor (gas) in the atmosphere. Water condenses into clouds and then falls back to earth as rain or snow (precipitation).
Algal Blooms - Rapid growth of algae on the surface of lakes, streams, or ponds; stimulated by nutrient enrichment.
Controlled waters are rivers, streams, estuaries, canals, lakes, ponds, ditches and groundwater as far out as the UK territorial limit. Most legislation relating to discharges of effluent (other than to sewer) applies to controlled waters.
Lakes and reservoirs which are relatively deep, do not freeze over during the winter months, and undergo a single stratification and mixing cycle during the year.
Algae that are often associated with problem blooms in lakes. Some produce chemicals toxic to other organisms, including humans. They often form floating scum as they die. Many can fix nitrogen (N2) from the air to provide their own nutrient.
Varve: Laminated clays and fine grained sediments of glacial origin deposited in lakes during the retreat of glacial ice. Each lamina or varve has a thicker coarser layer and a finer layer which represent a years seasonal cycle of deposition.
Turbid: Thick or opaque with matter in suspension. Rivers and lakes may become turbid after a rainfall.
Turbidity: Cloudiness caused by the presence of suspended solids in water; an indicator of water quality.
Hydrologic Cycle (Water Cycle): Water in its various manifestations as vapor evaporated from oceans, lakes, streams, and plants; rain and snow; snowpack or glacier; groundwater or surface runoff; and finally as streams and rivers returning to the sea.
The deposition of water-borne sediments in stream channels, lakes, reservoirs or on floodplains usually resulting from a decrease in the velocity of the water.

Direct run-off Water that flows from the ground surface directly into streams, rivers, and lakes.
Discharge Flow of surface water in a stream or canal.
Disinfectants Fluids or gasses to disinfect filters, pipelines, systems, etc.
HYDROLOGIC CYCLE: The movement of water as it evaporates from rivers, lakes or oceans, returns to the earth as precipitation, flows into rivers and evaporates again.
The capacity of bases to neutralize acids. An example is lime added to lakes to decrease acidity.
Allergen
A substance that causes an allergic reaction in individuals sensitive to it.

Litter- Waste that is improperly disposed of on the street, sidewalk, lakes and other bodies of water, and in the general environment.
Sediment
The soil, sand and minerals at the bottom of surface waters, such as streams, lakes and rivers. Sediments capture or adsorb contaminants. The term may also refer to solids that settle out of any liquid.
It can damage trees and lead to acid rain, which can harm lakes and streams and also corrode exposed materials. In the presence of sunlight and volatile organic compounds, NO2 can contribute to the formation of ground-level ozone, or smog.
Harvesting all the trees in one area at one time, a practice that can encourage fast rainfall or snowmelt runoff, erosion, sedimentation of streams and lakes, and flooding, and destroys vital habitat.

forests, lakes, oceans). Ecological diversity is the variety of biological communities that interact with one another and with their environments. Landscape diversity is sometimes included as a fourth concept.
Even though rains continuously replenish the clean water supply, we have polluted the rivers, lakes and streams making them unsuitable for drinking or agriculture. Further, we are rapidly draining the underground aquifers which took eons to fill.
