Has the Rio Grande run dry again this year? Which parts of the country are seeing the highest stream flows? Find out at this site from the U.S. Geological Survey, a compilation of data on water flow, depth, and quality from a whopping 1.5 million locales throughout the U.S. and Puerto Rico. Since last mentioned in NetWatch (27 August 1999, p. 1323), the site has been revamped and now offers real-time readings for both surface waters, such as streams and rivers, and groundwater. For variables like flow rate and depth, you can get daily, monthly, and yearly trends, as well as historical values. The site also dispenses water-quality data, including levels of minerals and algae-feeding nutrients like phosphorus.
