Animal tracks give us clues to past travelers

Take a hike on a trail and see who may have walked there before you. Both humans and animals leave behind footprints that you can identify by downloading the Delta Track Guide at the bottom of the page.

There are many places to hike at local parks that have unpaved, dirt or sand walking trails. Take along the track guide, which has a list of eight common Delta animals, and a paper and pencil. Watch the ground and keep an eye out for track marks. Each time you find a clear track on your walk, use the track guide to identify it.

You can use your paper and pencil to record what you found, where you found it and draw a picture of it. 


Take a look back at 2015...

Water too precious to waste

The Delta is where two of California’s largest rivers — the Sacramento and San Joaquin — meet. along with the Mokelumne, Cosumnes and Calaveras, they supply drinking water for 25 million people and irrigation water for countless acres of farmland.

Fresh, drinkable water is California’s most precious resource, so it is important to keep it clean and safe for all living creatures. Scientists constantly study Delta water quality to ensure it is safe to use. about 97 percent of all the world’s water is high in salinity or otherwise undrinkable. another 2 percent is locked in ice caps and glaciers. Conservation is key. The average american uses 50 gallons of water each day. a dripping faucet wastes up to 2,000 gallons a year.
