The Caching the Rain geotrail is a fun, family-friendly outdoor scavenger hunt activity that people can do to learn more about water quality, stormwater management facilities and actions they can take to reduce stormwater runoff and pollution. Under the program, participants (known as "geocachers") use Global positioning system (GPS) enabled devices, such as smartphones, to locate and find camouflaged containers called geocaches. Geocaches associated with the Caching the Rain geotrail are placed on public property near stormwater management facilities throughout the County.
