About US Hydrography Map
Crossing a raging river in the middle of a backpacking trip should never come as a surprise. With this new map, you can plan more effectively with data sourced from USGS National Hydrography Data Set.
The US Hydrography Map represents the water drainage network of the United States, including Hawaii and Alaska, with features such as rivers, streams, canals, lakes, ponds, coastline, dams, and stream-gages. Community stewards and users update and maintain the data.
US Hydrography has a scale of 1:24,000 scale or 1:63,360 in Alaska, and reveals more details as you zoom in on the map. Click on water features to learn more about the type and size of the body of water.
