If you're reading a map of lake-surface levels, those numbers usually show the level of what they call "mean lower low water". That's the water level, averaged over a long period of time, of the lower of the two low tides each day. So no, it's not the lowest, but it's the average of all of the daily "lowers". Later, when you read the tide prediction table or the fishing guide for a certain date, the numbers you see there for high- and low-tide are referenced to "mean lower low water", which I'm guessing is the number on the map.
the Low Low is for a Very Low level Alarm, or an emergency status. the Low is just a low level switch who activate any normal output
salt
when rainwater and runoff, as well as underground streams of water dissolve minerals in the rock or soil which includes salt, and reach the water body with a higher concentration of salt than the water body. salt increase can also be caused by evaporation of the water, which reduces the water level while maintaining the same salt content, hence more salt in less water. salt being lost can occur through desalination or harvesting of salt, as well as rain and runoff which travels overland, hence gaining much less salt, and diluting the overall salt content of the water body.
low height. below sea level
3/31/2013: Visited yesterday. LOW!
water always flows from high level to low level. Also in drainage the principle is high level to low level....
They consider high and low tides in their journey because if it is high tide the water level will be high but if it is low tides the water level is low.
the water level in the arctic tundra will get about to 4 feet low. the highest this water can get is about 1,000 feet

When oxygen levels in water get low... When algae takes over a lake. The oxygen levels will get low.
In high tides areas, the water level is higher the average sea level. In areas between high tides, low tides from. In low tide areas, the water level is lower than average sea level.
It contains the former town of St. Thomas, Nevada which can sometimes be seen when the water level is low. It also holds a B-29 which crashed into it in 1948.it was made by the rising water from the construction of the hover dam
Lake Hefner is one lake that provides water to Oklahoma. Another lake that provides water to Oklahomans is Lake Overholser. Many of these lakes in recent years are starting to dry up and recede due to low precipitation and a long standing drought.
