Photos: Fargo's sand, clay and dirt flood walls

2 Crews fill trap bags with dirt in Fargo, N.D. on Monday, April 22, 2013. The bags are flood barriers with a footprint small enough to allow the street they are on, 5th Street S, to remain open. 
3 A row of trap bags on 5th St. S in Fargo, N.D. were filled with sand on Monday, April 22, 2013. 
4 This clay levee was built Monday, April 22, 2013 to protect a neighborhood near Lindenwood Park in Fargo, N.D. from the expected rise of the Red River. 
5 Jason Hoogland with the city of Fargo picks up a smashed sandbag in front of a home on S River Road in Fargo, N.D. on Tuesday, April 23, 2013. The removal of flood-prone homes and installation of permanent clay levees mean the city does not need as many sandbags to fight the rising Red River this year. Fargo will have about 1.5 million sandbags available this year. 
6 Sandbags are delivered from Sandbag Central to homes on S River Road in Fargo, N.D. on Tuesday, April 23, 2013. 
7 City of Fargo Police officer Paul Lease watches as the last few pallets of sandbags are delivered to S River Road in Fargo, N.D. on Tuesday, April 23, 2013. Police will escort trucks from Sandbag Central to flood-prone neighborhoods Tuesday through Thursday of this week. 
8 A stack of sandbags is ready for placement on Tuesday, April 23, 2013 in the Oak Grove neighborhood of Fargo, N.D. High school students will help make dikes with the sandbags on Thursday and Friday of this week, and early next week if necessary.
