   Meltwater
  
  Meltwater is water released by the melting of snow or ice, including glacial ice, tabular icebergs and ice shelves over oceans. Meltwater is often found in the ablation zone of glaciers, where the rate of snow cover is reducing. Meltwater can be produced during volcanic eruptions, in a similar way in which the more dangerous lahars form.

   Water Jacket Melters function more like a large, commercial double boiler in that they keep substances evenly heated but generally heat up to only , since that is the boiling point of water. They can be made of aluminium, but are generally made of stainless steel. Unlike direct heat melters, water jacket melters can be almost unlimited in size, with 580 litres being common and up to the larger ~3800 litre melters and more.

   Coldwater Lake (Washington)
  
  Coldwater Lake is a barrier lake on the border of Cowlitz County and Skamania County, Washington in the United States. The lake was created during the 1980 eruption of Mount St. Helens, which blocked its natural outlet, Coldwater Creek, with volcanic debris. It is one of several lakes in the area that were created or otherwise enlarged by the eruption.
  
  Section::::Geography.
   BULLET::::- The lake is Monomictic Mixing type and develops thermal stratification in March to November. Maximum depth of the Thermocline is . Hypolimnion temperature ranges from to .

  BULLET::::- DO [mg l-1] value varied from a maximum of 10.4 on the surface to a minimum of 2.2 at the bottom in year over the 12 months period
   BULLET::::- A complex of lakes in Quincy, Algansee and Ovid Township, including Marble Lake, Middle Lake, Lake Bartholomew, Mud Lake, and Long Lake connect with Coldwater Lake to the south, which also forms the headwaters of the main branch of the Coldwater River

  BULLET::::- Tallahassee Creek (Tallahassee Drain) flows into Mud Lake and rises in section 22 of California Township, just north of Ray
   BULLET::::1. Meltwater is produced as a result of geothermal heating from below. Surface ablation water is not considered as it would be minimal at the glacial maximum and evidence indicates that surface water does not penetrate more than into a glacier.
  
  BULLET::::2. Meltwater initially drains through subglacial aquifers.
  
  BULLET::::3. When the hydraulic transmissivity of the substratum is exceeded, subglacial meltwater accumulates in basins.
  
  BULLET::::4. Water accumulates sufficiently to open the ice blockage in the tunnel valley which accumulated after the last discharge.

   Meltwater provides drinking water for a large proportion of the world's population, as well as providing water for irrigation and hydroelectric plants. Some cities around the world have large lakes that collect snow melt to supplement water supply. Cities that source water from meltwater include Melbourne, Canberra, Los Angeles, Las Vegas amongst others.

  The North Cascades features some of the most rugged topography in the Cascade Range with craggy peaks, ridges, and deep glacial valleys.
  
  Geological events occurring many years ago created the diverse topography and drastic elevation changes over the Cascade Range leading to the various climate differences.
   The Pleistocene deposits blanketing the Louisiana Continental shelf and slope between the mouth of the Mississippi River and Orca and Pygmy basins largely consist of sediments transported down the Mississippi River mixed with variable additions of local biologically generated carbonate. Because of this, the provenance of the meltwater and superfloods can be readily inferred from the sediment's composition. The composition of the sediments brought into the Gulf of Mexico and deposited on the Louisiana continental shelf and slope during the superfloods of MWF-5 reflect an abrupt change in mineralogy, fossil content, organic matter, and amount after 12,900 calendar years ago at the start of the Younger Dryas interval. First, after 12,900 calendar years ago, smectite-rich sediments from the Missouri River drainage are progressively and quickly replaced by sediments, which are associated with the Great Lakes region and further south along the Mississippi River, as indicated by their clay mineralogy. Second, after 12,900 calendar years ago, the overall quantity of sediment being transported down the Mississippi River abruptly decreases with a corresponding and significantly increased proportion of locally produced biologically generated carbonate and organic matter. Third, after 12,900 calendar years ago, various analyses, e.g. C/N ratio and Rock–Eval Pyrolysis, indicate that the type of organic matter present changes from organic matter that was reworked from old formations by glacials to well-preserved Holocene organic matter that is mainly of marine origin. Finally, after 12,900 calendar years ago, the presence of reworked nanofossils disappear from sediments accumulating on the Louisiana continental shelf and slope.
   Section::::Water quality.
  
  The lake experienced a bloom of blue-green algae in 1993 caused by low water, high phosphorus content, and hot weather. Studies of water quality found phosphorus to be present in high levels which contributed to the algal bloom. Beginning in 1995, the water quality was monitored and an improvement plan was implemented to lower the phosphorus by 37 percent. By 2003 the lake had 57 percent less phosphorus than the initial monitoring in 1995 due to the best management practices adopted in the drainage basin of the lake.

   The above changes in the nature of accumulating sediments indicate that after the start of the Younger Dryas, the southern route for Laurentide Ice Sheet meltwater was largely blocked. On the rare occasions it could flow southward, glacial meltwater flowed through Lake Agassiz and sometimes the Great Lakes to the Mississippi River. As the water moved through either Lake Agassiz or other proglacial lakes, they completely trapped and removed any glacial outwash and the older, reworked organic material and reworked nanofossils that the outwash contained. As a result, the sediment carried by the Mississippi River after the start of the Younger Dryas consisted of illite and chorite enriched sediments from the Great Lakes region that lacked any reworked nanofossils. These changes argue that the superfloods of MWF-5 which fed Meltwater Pulse B are related to either rare periods of southerly discharge of meltwater through Lake Agassiz, nonglacial periods of climate-enhanced discharge within the Mississippi River Basin, or a combination of both.
   This unusual flow of melt water from below the glacier gives scientists access to an environment they could otherwise only explore by drilling (which would also risk contaminating it). The melt water source is a subglacial pool of unknown size which sometimes overflows. Biogeochemical analysis shows that the water is marine in source originally. One hypothesis is that the source may be the remains of an ancient fjord that occupied the Taylor valley in the tertiary period. The ferrous iron dissolved in the water oxidizes as the water reaches the surface, turning the water red.

   An analysis of data from the "Mars Odyssey" neutron spectrometer revealed that the RSL sites do not contain any more water than found at anywhere else at similar latitudes. The authors concluded that RSL are not supplied by large, near-surface briny aquifers. It is still possible with this data that water vapor from deeply buried ice, from the atmosphere, or from small deeply buried aquifers.
