The Sacramento-San Joaquin River Delta region encompasses over
1,200 miles of waterways, located between Sacramento on the north
and Stockton to the south. It is the largest estuary on the US
Pacific Coast. The larger rivers feeding the Delta are the
Sacramento and the San Joaquin River. Other rivers include the
American River, Mokelumne River, Cosumnes River and the Calaveras
Environmentally sensitive and culturally significant, the Delta
is home to the “bread basket” of America. Delta water is
the lifeblood for hundreds of thousands of acres of farmlands
that feed not only California, but the nation.
The Delta is comprised of numerous channels or sloughs that have
resulted in a system of “islands” and wetlands protected by a
comprehensive levee system.
The Delta is a world-renowned destination for boating, fishing
and water sports. For most Discovery Bay residents, the town’s
proximity to the Delta and all that it offers is an integral part
of our way of life here.
Reclamation District 800 is responsible for the operation and
maintenance of nearly 19 miles of levees protecting 7,000 acres
of agricultural, urban, commercial and industrial land in and
around Discovery Bay. Rec 800 is responsible for:
The Sacramento-San Joaquin River Delta is comprised of over 1,200
miles of waterways that attract numerous forms of water
recreation including boating, fishing, waterskiing, wakeboarding,
jet skiing and more. Unfortunately though, the Delta also
“represents one of the state’s highest-accident areas” due to the
popularity of the area.
There are numerous online resources and printed materials
developed to educate recreational boaters. There are also local
boater safety courses you may want to consider.
Due to its location on the Delta, invasive aquatic weeds are
prevalent throughout Discovery Bay. The most common types
of invasive species are Egeria Densa, Water Hyacinth and the
Curly Leaf Pond Weed.
These weeds have tendencies to grow rapidly and are known to
block bays and waterways, making boating almost but impossible in
The state of California Department of Boating and Waterways (DBW)
has taken an aggressive stand against these weeds and have
chemically treated Discovery Bay to manage (not eradicate) the
variety of weed specie
In 1839, John Sutter and 13 others traveled the delta region to
search for settlement opportunities for others migrating from
Europe. The group navigated the Delta waters, departing from
Yerba Buena (San Francisco) and after 12 days they met up with
the American River, making land at what would eventually become
the capitol city (Sacramento).
