............................... TENNESSEE 4/29/2013 - Flooding along Cumberland River tributaries in Middle Tennessee has resulted in numerous road closures and some swift water rescues by local emergency management agencies. Approximately 3 to 4 inches of rainfall on April 27 and April 28 resulted in flashing flooding along Cumberland River tributaries in the Nashville and Clarksville, Tennessee areas. Tributaries affected included Mill Creek and Whites Creek in Nashville and the Red River at Port Royal, Tennessee. Approximate annual exceedance probabilities were in the 10 to 20 percent range and the peak stream flows were less than half the period of record extremes which occurred during the May 2010 flood. The flooding resulted in several road closures and the local media reports that some swift water rescues were needed but no deaths are reported. One stream gage on Whites Creek near Nashville was damaged. The USGS Tennessee Water Science Center has two crews deployed on April 28 to make discharge measurements and has been working closely with Metro Nashville staff throughout the weekend........... ILLINOIS 4/29/2013 - Flooding in Illinois. Flooding in Illinois is subsiding. Smaller streams in IL are generally back to near normal. However, downstream reaches of larger drainages are still near flood stage-- but with forecasted dry weather, they should continue to fall. The lower Illinois River at Valley City is predicted to finally reach its crest today or tomorrow. 4/25/2013 Illinois - The heavy rains last week produced record flooding throughout IL. At least 13 long-term streamgages reached new peaks of record. Most streams are now receeding, and within IL only the upper Fox River and lower IL River are still flooding. However, many streamgages on border rivers (the Wabash and Mississippi Rivers) are still in the "Major Flooding" category according to the NWS. USGS made 75 measurements during the event. Seventeen of those measurements were the highest measurements ever made at the respective streamgages, and 52 were in the top 5. The measurements were critical for the NWS, the Corps, the State of IL DNR Office of Water Resources, and other emergency management officials as they decided how and where to deploy their resources. The flood is wrapping up in IL, and this may be the last Project Alert notice from IL for this event. We still have two crews out measuring the lower IL River today as the crest moves through IL and into the Mississippi River. A CBS News team met one IL WSC crew at a streamgage yesterday, and that is expected to air tonight on the CBS National News. Thanks to MO WSC and IN WSC for thier assistance on this event, and thanks to the National Flood Coordinator for his help. Most of all, thanks to the Field Technicians who toiled and delivered under adverse conditions, long hours, and unreasonable/implausible requests................ 04/24/2013 - Moderate to Major flooding is occurring on the middle Mississippi River........................ INDIANA 4/25/2013 - Moderate to major flooding continues on the lower Wabash River. Moderate to major flooding continues on the lower Wabash River with the crest close to Riverton, IN at this time. 1-2 inches of rain fell across central Indiana yesterday including the central Wabash basin contributing to already oversaturated conditions in that area. The crest at Riverton should come later this morning and is predicted to be the highest since 1943 according to the National Weather Service (NWS). Predictions downstream show a more moderate level at this time from Vincennes to New Harmony. The USGS has 2 crews (4 people) out measuring flow at Vincennes and further downstream at Mt. Carmel, IL today. Officials in Vincennes are keeping a close eye on the Brevoort levee which protects the city from the floodwaters of the Wabash. They have described ongoing seepage of water through the levee and are quoted to have "major concerns" according to several news sources. The crest is expected around Saturday in this area. All gages are working correctly at this time across the state and have accurately recorded all peaks. The Indiana office has made 24 special measurements of discharge during this event. The USGS will continue to interact with the NWS, U.S. Army Corps of Engineers, state, and local officials for the duration of flood conditions. ............... NORTH DAKOTA AND MINNESOTA 4/23/2013 - Forecast major flooding in the Red River of the North Basin in North Dakota and Minnesota. Flood Risk for the Red River of the North in North Dakota and Minnesota. The spring melt for the Red River of the North is beginning and will be in full progress by this coming weekend. Current weather forecast show day time temperatures in the 50's and 60's, with overnight lows above freezing by the end of the week. Major flooding is forecast all along the main stem Red River of the North. Based on the most recent National Weather Service (NWS) probabilistic forecast for the Red River at Fargo, ND (110 years of record), there is a 40% chance that this year’s flood will exceed the peak of record that occurred on March 28, 2009. The Red River in Fargo is expected to reach the peak in the next 7 - 10 days. Most rivers and streams in the Red River basin are still ice covered, so USGS field personnel continue to make flow measurements where possible to aid the NWS in flood forecasting model calibration and the Army Corps of Engineers (USACE) in flood control reservoir operations. Two rapid deployment gages (RDG) have been installed in the Red River basin. One RDG is located in an ungaged tributary in the upper Red River basin upstream of Wahpeton, North Dakota; http://waterdata.usgs.gov/mn/nwis/uv/?site_no=05051350&PARAmeter_cd=00065,00060 The second RDG is deployed on the Red River in Grand Forks, North Dakota, with a water-surface velocity radar attached in an experimental effort to calculate real-time discharge values during open water periods. If successful an accurate discharge could be calculated in this low-gradient river allowing for more precise and timely flow data to be delivered to flood forecasters and flood fighting agencies such as the NWS and USACE. There are no results from this experimental effort as of this project alert since the Red River in Grand Forks is still ice covered. Communication with other agencies as been carried out, through conference calls, emails and NWS Chat........... MISSOURI 4/23/2013 - Moderate to Major flooding is occurring on the upper and middle Mississippi River. Currently there is one(1)crew deployed to make streamflow measurements at USGS and USACE (MVS) streamflow-gaging stations along the upper and middle Mississippi River in Missouri............
