Question: Both the Colorado River Aqueduct and the Cape Cod Canal are located in which country?
Context: The Colorado River Aqueduct, or CRA, is a 242 mi water conveyance in Southern California in the United States, operated by the Metropolitan Water District of Southern California (MWD).  The aqueduct impounds water from the Colorado River at Lake Havasu on the California-Arizona border west across the Mojave and Colorado deserts to the east side of the Santa Ana Mountains.  It is one of the primary sources of drinking water for Southern California. United States Coast Guard Station Cape Cod Canal is a United States Coast Guard station located in Sandwich, Massachusetts.  It operates patrol boats along the coast of Cape Cod, the Cape Cod Canal, and the treacherous waters of Buzzards Bay. Scusset Beach State Reservation is a state-operated, public recreation area located in the town of Sandwich in Barnstable County, Massachusetts, at the east end of the Cape Cod Canal on land formerly part of Sagamore Hill Military Reservation.  In addition to its beach and campgrounds, prominent features of the park include Sagamore Hill, a one-time Native American meeting ground and site of World War II coastal fortifications, and a 3000 ft stone jetty that separates the canal and beach.  Unlike most of Sandwich, this section of the town is on the mainland side of the Cape Cod Canal.  The state park is managed by the Massachusetts Department of Conservation and Recreation under a lease agreement with the U.S. Army Corps of Engineers. The Cape Cod Canal is an artificial waterway in the U.S. state of Massachusetts connecting Cape Cod Bay in the north to Buzzards Bay in the south. Bournedale is a village in the town of Bourne in Barnstable County, Massachusetts fronting Sagamore Beach, Buzzards Bay and the middle of the Cape Cod Canal.  Along with Buzzards Bay and Sagamore Beach it is one of only three communities in Barnstable County that are north of the Cape Cod Canal.  Another region in Barnstable County that are north of the Cape Cod Canal is Scusset Beach State Reservation. Sagamore Beach is a village of Bourne, Massachusetts fronting Cape Cod Bay and the east end of the Cape Cod Canal.  It occupies the northern half of the Sagamore census-designated place.  Along with Buzzards Bay and Bournedale, it is one of only three communities in Barnstable County that are north of the Cape Cod Canal. Jeremiah's Gutter was a canal located on the border of Orleans and Eastham, Massachusetts, the first canal to cut across the peninsula of Cape Cod.  It connected Cape Cod Bay in the west to the Atlantic Ocean in the east.  It was active for over 100 years, although it gradually fell out of use and was later replaced by the more widely known Cape Cod Canal. The Cape Cod Canal Railroad Bridge (also known as the Buzzards Bay Railroad Bridge), a vertical lift bridge in Bourne, Massachusetts near Buzzards Bay, carries railroad traffic across the Cape Cod Canal, connecting Cape Cod with the mainland. The San Diego Aqueduct, or San Diego Project, is a system of four aqueducts in the U.S. state of California, supplying about 90 percent of the water supply for the city of San Diego.  The system comprises the First and Second San Diego Aqueducts, carrying water from the Colorado River west to reservoirs on the outskirts of San Diego.  The 70 mi First Aqueduct consists of the pipelines 1 and 2, which run from the Colorado River Aqueduct near San Jacinto, California, to the San Vicente Reservoir, approximately 15 mi northeast of the city.  Pipelines 3 and 4 make up the 94 mi Second Aqueduct.  Together, these four pipelines have a capacity of 826 ft3/s .  The smaller, 12.5 mi Fallbrook-Ocean Branch branches from the First Aqueduct into Morrow Reservoir.  The La Mesa-Sweetwater Branch originates from the First Aqueduct, flowing into the Sweetwater Reservoir. The Cape Cod Canal Tunnel is a fictional tunnel allegedly built in the 1960s under the Cape Cod Canal.  The hoax has been popularized by the selling of bumper sticker permits.  It came into popular usage in Massachusetts as a commentary on often severe traffic on the bridges that lead to Cape Cod.  It has also been used by locals trying to trick tourists, directing them to a nonexistent entrance near the Massachusetts Military Reservation.  The other entrance of the tunnel supposedly exists in New Bedford.
