Based on the latest information available, the boat ramp named 1st Street in Asotin, Washington is a concrete boat ramp that measures approximately 20 feet wide. This boat ramp services the Snake River, a 1,078-mile-long river that flows through Idaho, Wyoming, Utah, Nevada, Oregon, and Washington.

The Snake River is a popular destination for recreational boating, fishing, and other water activities. However, due to the presence of several dams along the river, only certain types of watercraft are permitted on the water. These include powerboats, canoes, kayaks, and jet skis.

It is important to note that regulations and restrictions may vary depending on the specific location and time of year, so it is always advisable to check with local authorities before using any boat ramp or waterway.
