![]() ![]() When the level of a lake fluctuates it can impact things like navigation through canals, the use of docks and boat ramps, and wetland connectivity-which can also affect water quality. As the Chain of Lakes City, Winter Haven prides itself on its numerous waterbodies which serve as integral social, economic, and ecological resources for the community. Surface LevelĪlso known as lake stage or surface elevation, surface level represents the height of a lakes water level above sea level. If the YTD Net is positive, then the Winter Haven area has gained water for that year–and vice versa if it is negative. Year-to-Date (YTD) Net Rainfall is similar to the YTD Annual Rainfall chart in that it is a tally of total net rainfall for a given year. Net rainfall is typically negative in the dry season and positive during the wet season. Negative net rainfall means the Winter Haven area has lost water during that month. Since ET can be higher than gross rainfall, net values can be negative numbers. By subtracting gross rainfall from ET, we get total net rainfall. Monthly Net Rainfall is a chart that depicts total gross rainfall and total evapotranspiration (ET) in a given month. Once rainfall data has been collected for the entire 12 months, we can see where the annual total sits in relation to the long-term annual average (dotted line) which is 51.6 inches. Year-to-Date (YTD) Annual Total is a tally of all the gross rainfall that has fallen in the selected year to that point. This interquartile range represents the normal range of rainfall fluctuations in the given month. These monthly levels are plotted against the long-term average (dotted line) and the 25th to 75th percentile range (shaded area) for that month. Gross monthly rainfall depicts the total amount of rainfall that falls each month. This net gain or loss of water is important in tracking our drinking water supply and for predicting drought conditions. Water is lost from the area either as evapotranspiration (evaporation + plant uptake) or flow to downstream areas. In fact, Winter Haven’s lakes act as part of the headwaters for the Peace River which flows to the Gulf of Mexico via Charlotte Harbor. Due to our geographic location at the top of a ridge, Winter Haven is a purely rainfall driven hydrologic system-meaning that the source of all surface and groundwater is derived from rain as opposed to water flow from upstream. Locally, the predominant form we see is rainfall. rain, snow, sleet, hail), it is referred to as precipitation. ![]() Looking to integrate weather data in your website or app?
