The Copper River is located in south-central Alaska, where it is also called Ahtna River. The river drains a large region of the Chugach and Wrangell mountains. It is the longest river in Alaska, at 665 miles long. It flows primarily south. The Copper Valley is situated along its banks. The water flows into the eponymous reservoir in the delta. In the past, the river was a major source of salmon and other fish.
The Copper River Delta is home to 36 species of shorebirds. These birds need huge amounts of energy to navigate the vast wetlands, and tidal mud flats provide the energy that they need. Some shorebirds stay on the delta to breed, but most migrate north to other wetlands in the state. This unique ecosystem provides a major stopover site for many other species. For this reason, the area has become a major birding and wildlife attraction.
The area has also become an important fishing ground for salmon and king salmon. The river’s sediments have created mudflats along 65 miles of the coast. These mudflats have attracted bears, moose, and spawning salmon. The habitat has helped the fish population flourish. The area’s rivers provide food and habitat for numerous wildlife species. Hundreds of thousands of birds come to the Copper River Delta every year.
The copper river delta’s salmon population thrives. There are three species of salmon in the area, and the rivers are a natural highway for them. The rivers are home to many other wildlife, including brown and black bear, wolves, mountain goats, and sheep. In mid-July, the area is host to the Copper River Salmon Jam, a festival celebrating the local salmon runs. This event features road races, music, art fairs, and several activities.
The Copper River Delta is home to more than 1.1 million shorebirds each year. This amount is unprecedented for a single region in the world. The region is home to diverse wildlife, including some of the most endangered species. The Delta is also a vital stop for millions of migratory birds traveling the Pacific Flyway. Approximately ten million migratory birds breed in the area each year. It’s a thriving ecosystem that is essential for many species.
The climate in the Copper River Delta is a tropical coastal marine climate. It is mild and wet, and is affected by the Gulf of Alaska’s Alaska Current. Warm ocean air and low-pressure systems are transported to the Delta. They are trapped by the Chugach Mountain Range, thereby increasing ambient humidity. The temperature in the delta can range from warm to cold, depending on what is happening in the watershed. A dust storm in November can make the atmosphere dusty and dry.
