How much water is in Park creeks? We will now know the approximate water flow (discharge) every 15 minutes for six of the ten perennial streams and one ephemeral stream in the Park. The USGS installed ten stream gages in September and October to collect a long-term record of water amounts. These gages are located on Strawberry Creek, Lehman Creek, Rowland Springs, Baker Creek, Upper and Lower Snake Creek, South Fork of Big Wash, Decathon Canyon, Williams Creek, and Shingle Creek. Each site has a pressure transducer, which measures the height of water in the stream; a staff plate, from which a person can read the stream height; and a temperature datalogger. Every four to six weeks a technician downloads the pressure transducer data and measures the discharge. One of the stream gages, on Lehman Creek, transmits its data via satellite to a website every four hours. You can view this data, which is considered provisional (subject to checking and revision by a USGS analyst), at http://waterdata.usgs.gov/nv/nwis/uv?10243260.
