............................... NORTH DAKOTA 5/21/2013 - Major flooding is occurring at at three locations in northeast North Dakota. The flooding is the result of three days of state-wide rainfall with upwards of 5 inches in places. The dry soils throughout the state mitigated most of the impacts, with most gage locations experiencing minor flooding. The three locations, Little South Pembina River nr Walhalla (05099400), the Pembina River at Walhalla (05099600) and the Tongue River at Akra, all located in the northeast part of the state, are experiencing record or near record flooding. All three locations have an AEP in the .04 to .02 range. A rapid deployment gage (RDG) has been installed on Lake Renwick (right upstream of the Akra gage) so the state and local emergency managers can monitor the record water levels in the lake. http://waterdata.usgs.gov/nd/nwis/uv/?site_no=484637097450200&PARAmeter_cd=63158,00065,00060 Four USGS crews have been making additional discharge measurements for this flood event since Monday. Crews will actively measure and collect water quality samples for the next few days in order to document the receding limb of this flood event........... GEORGIA 5/21/2013 - Crews from the USGS Georgia Water Science Center continue to make streamflow measurements this week in response to the heavy rains from past weekend. Several crews from the Georgia Water Science Center continue to make high-flow measurements through Tuesday due to the heavy rains that occurred across north Georgia this past weekend. While the runoff event for smaller streams has largely passed, the focus is now on the mainstem Chattahoochee, Etowah and Coosawattee Rivers below major USACE dams that are releasing to lower lake levels. Releases from Lake Lanier, Allatoona Lake, and Carters Lake have raised river flows downstream to conditions that have not been seen for many years. These measurements are expected to continue through Thursday.Moderate flooding is occurring at locations across North Georgia and Gwinnett County due to record daily rainfall totals for May 18. Rainfall totals from 3.5 to over 5 inches of rain during this timeframe caused many streams to exceed the NWS flood stage over the weekend. Today, while the smaller streams have crested, the larger rivers remained high enough to require flood measurements and water-quality sampling around the Gwinnett County area. Six crews from the USGS Georgia Water Science Center have responded today to measure flood waters and flag high water marks. Additional rainfall is forecast for today, and an assessment of measurement needs will be made early tomorrow again.
