tection, primarily for the city of Minot, N. Dak., is under review by the Board of Engineers for Rivers and Harbors. The Red River Valley, is a fertile, relatively flat area with severe flood problems due to the flatness and the fact that the river flows. north and spring melt frequently occurs in the headwaters while downstream areas are still frozen. We have completed several projects but there is still much to do. Several interim studies are underway. The fiscal year 1968 budget also contains funds for initiation of a comprehensive framework study of the Souris-Red region including the Lake of the Woods area. (Slide 4) Last year's major flood caused estimated damages of about $12 million. This slide shows the Red River in flood on April 5, 1966, near Hallock, Minn. In the Upper Mississippi River Basin (slide 5) we have in addition to the Mississippi River proper, several large tributaries on which we have many flood control projects. Some are completed, others are in the planning stage or under construction and some are still in the study stage. Red Rock on the Des Moines River, about 80 percent complete, is a typical example of a reservoir project. This slide (slide 6) shows an aerial view of the dam and control structure looking upHere (slide 7) is a closeup of the gates in the control struc ture. (Blank 8) On the Mississippi River, frequently called the "Father of Waters,” there are 29 locks and dams between St. Louis and Minneapolis, 25 of these are in North Central Division. This system of locks and dams forms a 9-foot channel for barge traffic. This slide (slide 9) shows Lock and Dam No. 15 at Rock Island. The lock is 110' x 600'. The building on the right is the Rock Island District Office. In the background is the Rock Island Arsenal. The next slide (slide 10) is of Lock No. 19 at Keokuk, Iowa. This is one of the two 110 x 1,200 foot eks on the river. The other one is located near St. Louis, Mo. Studies to consider a 12-foot project as well as year round navigation re underway. (Blank 11) This mighty river, so important to the economy of mid-America, an also go on a rampage and wreak great havoc such as in the record food of April-May 1965. Here (slide 12) is a view of Dubuque, Iowa, aring the flood. This (slide 13) shows inundation of Davenport, Iowa. In spite of extensive flood fighting throughout the basin 15 Tes were lost and damages amounted to an estimated $158 million. Completed projects prevented additional damages of $40 million. It estimated that the extensive flood fighting efforts prevented addifional damages of $280 million. This slide (slide 14) shows a typical completed levee at Muscatine, Iowa. This one (slide 15) shows a completed floodwall at St. Paul, Minn. 1966 ICE JAM (Slide 16). In February 1966 localized flooding occurred immediely downstream from Rock Island, Ill., due to an ice jam. Here is a Tew of the ice jam from Dam No. 15. Note the resultant flooding in Davenport on the right. This aerial view (slide 17) gives you some idea of the extent of the ice jam. (Approximately 10 miles). Note the black streaks. Coal dust was spread by airplanes in an attempt to expedite melting. Although the streaks may not look too impressive, they represent 75 tons of coal dust. Note the island immediately to the left of the streaks. This is Horse Island which will be discussed later today I'm sure. A study is underway to identify causes and develop methods for relief of ice jams. (Blank 18). The Mississippi River also offers an unusual opportunity for recreation. Starting near the source we have the Headwaters Reservoirs which originally served navigation by low flow augmentation but now constitute an important recreational area as indicated by the next slide (slide 19). At many sites along the river we are providing recreational areas as typified by this slide (slide 20) and small boat harbors (slide 21) like this one at Muscatine, Iowa. ILLINOIS WATERWAY We now come to the Illinois Waterway (slide 22) the connecting link between the Mississippi River and the Great Lakes. Eight locks and dams provide a nine-foot channel for year-round barge traffic. A study is underway to consider providing a 12-foot project depth. Preconstruction planning is also underway to provide new 110′ x 1200' locks to supplement the present 110' x 600' locks. We estimate that the capacity of the present system will be reached by 1972. The next slide (slide 23) is an aerial of the present Lockport Lock. The first new lock to be constructed under the project now in the planning stage, will be located between the railroad and the present lock. The railroad will be relocated to make room for the new lock. (Blank 24). We now come to the Great Lakes Basin (slide 25). Here the predominant emphasis to date has been on navigation. The increasing size of ships engaged in the movement of iron ore, coal, grain and limestone, and the completion of the St. Lawrence Seaway and its ensuing increase in overseas commerce has necessitated the improving and deepening of the harbors. Altogether, there are 58 completed deep draft (18'-27′) Federal Harbors on the Great Lakes. Typical of our Great Lakes Harbors is Chicago Harbor shown on this slide (slide 26). (Slide 27) At Sault Ste. Marie, Mich., between Lakes Superior and Huron, a new lock 110 by 1200 feet is nearing completion to handle the largest ships anticipated on the Great Lakes. This slide is an aerial view of the lock area and the new lock construction. These are the busiest ship locks in the world. In 1966, 102 million tons passed through these locks. This slide (slide 28) is a closeup showing construction of the new lock walls. NIAGARA FALLS (Slide 29) We now move to Niagara Falls where our activities this past year have attracted much public interest. This slide is an aerial view of the area. The American Falls is in the center and the Horseshoe Falls is on the right. A study is underway to determine the feasibility of removing the talus at the foot of the American Falls and reinforcing the face of the falls to reduce further erosion all in the interest of preserving this natural wonder. Flow over the falls was reduced in November so we could inspect the rock structure over which the water flows. This slide (slide 30) shows the American Falls in 1918. Note the amount of talus at that time. Here is a picture of the falls as they exist today (slide 31). Note the talues accumulation. Note the amount of water going over the falls. Next (slide 32) we see the falls with the flow reduced. (Blank 33.) While the falls present a beautiful spectacle to honeymooners and tourists, they present a formidable obstacle to navigation. Canada therefore built the Welland Canal bypassing the falls in order that ships may pass between Lakes Erie and Ontario. This canal, however, is expected to reach its capacity by 1985. Therefore, a study is underway to investigate a new Lake Erie-Lake Ontario canal from a point near Buffalo, N.Y., to Wilson, N.Y., on Lake Ontario. This study is scheduled for completion in fiscal year 1970. INTERNATIONAL ASPECTS As you can see from this last slide (slide 34) over one-half of the United States-Canadian border, excluding Alaska, lies within the north central division. Thus there are international aspects to many of our activities. We work very closely with Canada on the levels and flows of the waters of Lakes Superior and Ontario, the control of flow at Niagara Falls and are currently engaged in a joint international study to determine the feasibility of further regulating all the lakes. In my capacity as Division Engineer I am the U.S. Chairman of the: International Great Lakes Levels Working Committee. GENERAL INVESTIGATIONS Mr. BOLAND.
