Lake Brunner is the largest lake in the West Coast region, 10 km (6.2 mi) across with an area of 4061 ha, just over 40 km 2 (15 sq mi). [1] The outlet of the lake is the Arnold River, a tributary of the Grey River / Māwheranui, next to the largest settlement of Moana, on the north shore of the lake.
Water resources and water pollution come under the jurisdiction of the Resource Management Act and is controlled by the regional councils - for the West Coast it is the West Coast Regional Council. A 2008 State of the Environment report reported that: [1] acid mine drainage has significant effects on freshwater ecosystems
Lake-effect rain forms in a smilar way to lake-effect snow: cold air moves across the relatively warmer waters of lakes, thereby creating a sharp drop in temperature from the lake surface through the first several thousand feet in the atmosphere (the temperature gradient is known as the "lapse rate"), and then it precipitates the moisture over ...
When lake-effect snow hits regions of the Great Lakes during late fall and winter, you start to hear meteorologists use terms like "feet of snow," "whiteout conditions," "blizzard" and "travel ...
Lake-effect snow, which can last for only a few minutes to several days, develops from narrow bands of clouds that form when cold, dry arctic air passes over a large, relatively mild lake.
In this way depressions intended to trap runoff water—before it flows to vulnerable water resources—can connect underground over time. Cavitation of surfaces above into the tunnels, results in potholes or caves. Deeper ponding exerts pressure that forces water into the ground faster. Faster flow dislodges contaminants otherwise adsorbed on ...
Several communities across the Great Lakes region are preparing to be blasted by feet of snow as winter weather moves in just as millions of people across the U.S. ring in 2025.
Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
