Crime statistics are compiled from UCR data and published annually by the FBI in the Crime in the United States series. The FBI does not collect the data itself. Rather, law enforcement agencies across the United States provide the data to the FBI, which then compiles the Reports.
Watershed Analysis. A watershed is the area of land where all of the water that falls in it and drains off of it goes into the same place or common outlet. A watershed is also defined by topographic divides between two or more adjacent catchment basins, such as a ridge or a crest.
A watershed is the area of land that drains into a body of water. The watershed also includes the creeks and other water bodies in the area. The quality of a water source depends greatly upon the watershed. The contaminants in a watershed will end up in the surface water body. This is the reason that watershed management is important.
