"Watersheds
What is a watershed?
Watersheds are defined by the USGS as the land area that drains water to a particular stream, river, or lake. It is a land feature that can be identified by tracing a line along the highest elevations between two areas on a map, often a ridge. Large watersheds, like the Mississippi River basin contain thousands of smaller watersheds.
There are several terms related to watersheds. The USGS has created a nationwide identification and naming schema known as the National Hydrography Dataset (NHD). The NHD identifies different drainage areas based on their size. The schema begins with a region, then a sub-region, basin, sub-basin, watershed, and finally a sub-watershed. These areas are used by different federal, state, and local governments and organizations to assist in protecting our waters. They use these different areas to help determine where to focus study efforts and provide funding. By identifying these different drainage areas, organization at different levels are able to cooperate and work together to help protect our waters.
For example,
the watershed for a large stream, like the Trinity River, is generally broken up into several smaller watersheds that are collections of catchments. The areas of land draining to small tributary streams are often called a catchment. The Texas Parks and Wildlife Department has prepared this map to show the Trinity watershed from its head waters in the north and west, until it empties in the Gulf of Mexico, just east of Houston. Remember that the map to the left shows some of the smaller watersheds that make up the entire Trinity Watershed."
This particular sign is located along N Carroll Street at the 400 block of W Congress Street on the west side of downtown Denton. It is part of a Denton’s County Stormwater public information campaign to remind residents that they’ll be swimming and playing in what they dump in the streets within the Lake Lewisville watershed.
