This U-shaped bend in the Napa River, known as an oxbow, is the start of the Napa dry bypass. Once the surface elevation of the water rises above the 13-foot mark, it will overtop this bank and be diverted through a straight passage back to the Napa River. The dry bypass is the latest in a series of flood risk reduction projects the Corps of Engineers and Napa County Flood Control and Water Conservation District are partnering on to help prevent flooding in downtown Napa. A ribbon-cutting ceremony is scheduled for August 4, 2015, to celebrate the project's completion. (U.S. Army photo by Luke Burns/Released)

Staff from the SFWMD Homestead and West Palm Beach field stations worked tirelessly throughout the week to install the temporary pumps at the S-176 structure. Their efforts will enable the District to move water more quickly out of Water Conservation Area 3A.

The Maeslant Storm Surge Barrier is on the Nieuwe Waterweg, the ship canal the connects the port of Rotterdam to the North Sea. Its two gates are each 22 meters high and 210 meters long. If a storm surge of greater than 3 meters is anticipated, the barriers will close automatically to protect Rotterdam and the vital Europort from flooding. It was completed in 1997 at a cost of 450m Euros.

Winner of Men’s Youth classification: Zaha Wolfe.
The 1st annual LA River Boat Race was held on August 30, 2014 on a 3/4 mile course consisting of small rapids and flat water located along a stretch of the river along the Glendale Narrows in the Elysian Valley. Almost a 100 participants competed in a variety of classifications that included Mens and Womens Advanced, Intermediate and Beginners as well as Youth, Tandem and Stand-Up Paddle boat. Noted Environmentalist Ed Begley Jr. kicked off the race as the first participant, which had racers going down the course solo and racing against the clock. The race was organized by L.A. River Expeditions which was founded by George Wolfe who led the 2008 LA River Expedition that led to the river being classified as a navigable river by the EPA and consequently protected under the clean water Act.

Affluent waste water arrives from a local Phoenix treatment facility to the wetlands Jan. 23, 2010. The ecosystem naturally cleans the water before its release back into local waterways. The U.S. Army Corps of Engineers Los Angeles District built the world's largest manmade wetlands for the city of Phoenix Water Services Department, reaching an environmental-restoration milestone that not only establishes and restores an historical habitat along the banks of the Salt River, but integrates cost-effective water quality improvement, storm water management, water conservation and reuse.

U.S. Army Corps of Engineer technicians begin pulling the needles from the bays of the Bonnet Carre’ Spillway on the morning of May 9, 2011. Due to heavy rains and snow melt from areas of the upper Mississippi River Valley, Mississippi River Commission President Maj. Gen. Michael J. Walsh, commander of the Corps' Mississippi Valley Division in Vicksburg, MS. gave the order to open the spill way to alleviate pressure on the levee system protecting the greater New Orleans area. Water flowing through the spillway will end up in Lake Pontchartrain.

Since the 1930s, US Route 93 snaked down the Nevada side of Black Canyon and crossed the Colorado River over Hoover Dam to Arizona. The massive dam was built between 1931 and 1936 and was the largest U.S. Government construction project up to that time. Enough concrete was used to build a road from San Francisco to New York City.
Construction on the Highway 93 bypass from which this photo was taken took five years, from 2005 to 2010 - the same amount of time it took to build the dam itself.
I went to the Nimbus Dam in Folsom California to see if there was any water being released after all of this rain. Most of the flood gates were open, but not all.

The upper end of the Yolo Bypass isn't really easy to access unless you know where to go and how to get there, but it's a gorgeous area and was spectacular yesterday as water began spilling over the Fremont Weir for the second time this winter. Huge towering clouds and a blue sky (at least for a few minutes) made the scene that much more appealing.
The Bonnet Carré Spillway is a flood control operation in the Lower Mississippi Valley. Located in St. Charles Parish, Louisiana – about 12 miles (19 km) west of New Orleans – it allows floodwaters from the Mississippi River to flow into Lake Pontchartrain and thence into the Gulf of Mexico. The construction of the Spillway was completed in 1931.
The Bonnet Carré Spillway consists of two basic components: a control structure along the east bank of the Mississippi River and a floodway that transfers the diverted flood waters to the lake.[3] The control structure is a mechanically-controlled concrete weir that extends for over a mile and a half parallel to the river. When opened, the control structure allows overflow volume to flow into Lake Pontchartrain. The lake's opening to the gulf is sufficient to absorb and dissipate any conceivable volume of flood flow. Thus, the flood surcharge portion of the water from the Mississippi is divided between the main river and the diversion channel; with the surcharge bypassing the New Orleans metropolitan area, resulting in the Mississippi being lower (through that area) than it could have been; and reducing the stress on the area's levees that line the river. Confined by guide levees, the floodway stretches nearly six miles (10 km) to Lake Pontchartrain, with a design capacity of 250,000 cu ft/s (7,100 m3/s).[4] The spillway is crossed by U.S. 61 and Interstate 10.
The spillway was built in response to the Great Mississippi Flood of 1927 that inundated much of the Mississippi River basin. It was first opened during the flood of 1937, and ten times thereafter through 2016 to lower river stages at New Orleans. The most recent opening began March 8, 2018,[5] when river levels in New Orleans were predicted to approach the flood stage of 17 feet (5.2 m) at the Carrollton Gauge which is located just upriver from Downtown New Orleans. en.wikipedia.org/wiki/Bonnet_Carr%C3%A9_Spillway.

From 1998 to 2002, the Milwaukee Metropolitan Sewerage District (MMSD) constructed a large urban flood management and stream restoration project on and around Lincoln Creek, on Milwaukee's north side.
Quoting from MMSD's web site: "Serving as a national model for urban flood management, the $120 million Lincoln Creek Flood Management Project reduces the risk of flooding for more than 2,000 homes and businesses along a densely populated 9-mile-long creek in Milwaukee, Wisconsin. The waterway is substantially safer with improved water quality and habitat for fish, birds and other wildlife." (www.mmsd.com/what-we-do/flood-management/lincoln-creek)
This photo shows the bridge at Green Tree Road, just east of 51st Street. The upstream (north) face of this bridge is fitted with a hydraulic control structure to hold floodwater in MMSD's Green Tree Reservoir and reduce flood flows downstream.

Tjitte Nauta of Deltares presents the outcomes of the afternoon workshop for his team: "Climate Adaption on a Regional Scale". Also in this picture are Jayantha Obeysekera (director modeling department of SFWMD), and Kim Shugar, head of the interdepartemental climate change group of South Florida.
SFWMD Fort Lauderdale Field Station recently completed two major gate overhauls at the G-57 coastal structure in Broward County.
The work is part of the District's extensive program of structural maintenance and upgrades — carried out primarily during the dry season — that is critical to ensuring the regional flood control system operates at optimal capacity.

In Albuquerque, New Mexico, Carlisle Blvd. passes over the Embudo Arroyo flood control channel - pedestrians can avoid the traffic by using this walkway. I doubt too many actually do.
