this creek as it does for Sope Creek and others in the area, nor did it set an official flood stage for it until after the 2005 flood. Minor flood stage is now considered to be , while major flood is , both at the Shallowford gauge. The highest the original gauges could read was , replaced with ones after the 2005 flood. Flooding Until 2009, the most severe flood known to have occurred on Noonday Creek was in July 2005, when the outer bands of Hurricane Dennis followed Hurricane Cindy by just a few days. Massive rainfall occurred, particularly with Dennis, in less than 24 hours, sending the creek to a level of late on July 10. That is about ten times its normal depth or height, reaching beyond what the Federal Emergency Management Agency (FEMA) and GDNR labeled its 100-year flood plain, largely because of excessive urbanization upstream. Because of this, many people did not have flood insurance. September 2009 record flooding In September 2009, an even worse flood occurred due to a stalled weather system, and the training of heavy showers and thunderstorms over the area. On September 21, the creek rose even higher than in 2005, blocking not only Georgia 92, but also Interstate 575 at the southern end of the ramps to 92, and flooding the Towne Lake Parkway diamond interchange and underpass (and a gas station) beneath 575 one exit north. Traffic was detoured at Chastain Road (two exits south of 92), but it also flooded at the creek and was barricaded to all traffic to the east, making it very difficult to reach alternate routes. Because of the many closures caused by the creek's inundation, residents of Woodstock and points northward found it took hours to get home, the resulting gridlock extending rush hour well past dusk, with heavy traffic still waiting to get home at 9:00pm on old Georgia 5, which was also blocked north of Woodstock due to the Little River. The 2009 Atlanta floods were called "of historic proportions" by the local National Weather Service forecast office (NWSFO Peachtree City). Noonday Creek at Shallowford Road crested at , with a peak flow literally off the chart, extrapolated to be about per second, compared to an average of 68. This was after receiving at least of rain in the past week, half of which fell around midday on September 21, at
