SACRAMENTO, Calif. — While the national streamflow database is documenting evidence of California’s historic drought, the database is also confirming another recently seen hydrologic phenomenon: earthquake-induced increases in streamflow.
Rivers and streams across California are flowing at record lows. Streamflow data from 182 U.S. Geological Survey streamgages in California with at least 30 years of record, currently show that 62 percent of streamgages are recording flows less 25 percent of normal, and 44 percent are recording flows less than 10 percent of normal. At several streamgage sites, scientists have had to extend measurement scales and rating formulas that help calculate accurate streamflow, because of record low water flows.Increased flow over rock riffle in Sonoma Creek seen after South Napa Earthquake of August 24, 2014.

Meanwhile, in the aftermath of the August 24 magnitude 6.0 South Napa Earthquake in California, water has begun to flow again in some previously-dry surrounding creeks, rivers and streams prompting many nearby residents to scratch their heads.
Hydrogeologic responses to earthquakes have been known by scientists for decades. In the case of the South Napa Earthquake, the discharge of springs and groundwater to some streams has increased. Based on experience in previous earthquakes, stream and spring flows are expected to decline again over the next several months, assuming that the Napa region does not get significant rainfall over that time period.
Post-earthquake changes in streamflow were recorded at a USGS streamgage on Sonoma Creek, near the city of Sonoma where measured increases in streamflow began after 4:15 a.m. on August 24, about an hour after the earthquake occurred. Streamflow has increased intermittently since the earthquake from 0.1 cubic feet per second to nearly 3 cfs on September 12. The median historical streamflow for this time period is about 0.5 cfs. Scientists theorize that this increase in streamflow is due to groundwater flow entering the river, and the intermittent nature of the streamflow is due to the non-uniform release of groundwater across the basin.

OLYMPIA, Wash. - The Federal Emergency Management Agency today announced it is expanding disaster assistance to Kittitas County.
The disaster aid helps the county pay for repair, restoration, reconstruction or replacement of public facilities, roads and bridges, water facilities and other infrastructure damaged or destroyed by wildfires that occurred between July 9 and Aug. 5.
Kittitas County has been added to the major disaster declaration of Aug. 11, which provided assistance to Okanogan County and the Confederated Tribes of Colville Reservation.Language English

Department of the Interior scientists are generating and sharing critical information to aid the recovery of the areas impacted by Hurricane Sandy, helping to protect our valuable coastal resources and to make communities more resilient against future extreme storms. Moving forward DOI is positioned to help answer questions such as: What locations along the coast are forecasted to be the most vulnerable to future hurricanes? What were the storm impacts to ecosystems, habitats, fish and wildlife? What is being learned about the importance of undeveloped land? Come learn how the U.S. Geological Survey and its partners are working to assemble and apply better data to keep citizens safe.

Newly released US Topo maps for Oregon now feature segments of the Pacific Crest National Scenic Trail. Several of the 1,835 new US Topo quadrangles for the state now display parts of the Trail along with other improved data layers.
“Having the Pacific Crest NST finally show up on Oregon US Topo maps is significant for all of the recreational users of the wild spaces the trail traverses,” said Tom Carlson, Geospatial Liaison for the Pacific Northwest. “Hiking the trail provides commanding views of the volcanic peaks of the Cascade Range as well as the verdant forests of the western side of the mountains and down into the farmlands of the Willamette Valley. You also see parts of the open Ponderosa Pine forest and high desert on the eastern slopes of the mountains.”
The Pacific Crest National Scenic Trail is a treasured pathway through some of the most scenic terrain in the nation. Beginning in southern California at the Mexican border, the PCT travels a total distance of 2,650 miles through California, Oregon, and Washington until reaching the Canadian border. The PCT is one of the original National Scenic Trails established by Congress in the 1968 National Trails System Act and fifty-four percent of the trail lies within designated wilderness.
The USGS partnered with the U.S. Forest Service to incorporate the trail onto the Oregon US Topo maps. This NST joins the Ice Age National Scenic Trail, the Pacific Northwest National Scenic Trail and the North Country National Scenic Trail as being featured on the new US Topo quads. The USGS hopes to eventually include all National Scenic Trails in The National Map products.
Another important addition to the new Oregon US Topo maps in the inclusion of Public Land Survey System. PLSS is a way of subdividing and describing land in the US. All lands in the public domain are subject to subdivision by this rectangular system of surveys, which is regulated by the U.S. Department of the Interior.
To compare change over time, scans of legacy USGS topo maps, some dating back to the late 1800s, can be downloaded from the USGS Historical Topographic Map Collection
To download US Topo maps: http://nationalmap.gov/ustopo/The National Trails System was established by Act of Congress in 1968. The Act grants the Secretary of Interior and the Secretary of Agriculture authority over the National Trails System. The Act defines four types of trails. Two of these types, the National Historic Trails and National Scenic Trails, can only be designated by Act of Congress. National scenic trails are extended trails located as to provide for maximum outdoor recreation potential and for the conservation and enjoyment of nationally significant scenic, historic, natural, and cultural qualities of the area through which such trails may pass.
There are 11 National Scenic Trails:
- Appalachian National Scenic Trail
- Pacific Crest National Scenic Trail
- Continental Divide National Scenic Trail
- North Country National Scenic Trail
- Ice Age National Scenic Trail
- Potomac Heritage National Scenic Trail
- Natchez Trace National Scenic Trail
- Florida National Scenic Trail
- Arizona National Scenic Trail
- New England National Scenic Trail
- Pacific Northwest National Scenic Trail
Eatontown, N.J. -- Hurricane season officially begins each year on June 1, but unlike firemen’s fairs, cookouts and fun at the beach, the season for hurricanes doesn’t end along with the summer.
