Missouri Department of ConservationView Photo(s) of Award Presentation The work was done in support of MDC’s response to the proposed revisions of the Corps’ Missouri River Master Manual. MDC scientists believe that a reduced flow condition in the late summer can provide considerable benefit for fish and wildlife. The model that was developed quantifies the acreage and juxtaposition of sand and water depth classes at numerous flows, and suggests that many uses, including commercial barge navigation and increased recreational opportunities, are supported by MDC’s proposal.
Business Problem This analysis presents an alternative to the U.S. Army Corps of Engineers’ (COE) proposals in the Revised Draft Environmental Impact Statement (RDEIS) for the Missouri River Master Water Control Manual (Master Manual). The Missouri Department of Conservation (MDC) geographically analyzed river depths produced by a Missouri River flow of approximately (~) 41,000 cfs at Kansas City (KC), Missouri, and compared them to depths at flows under the Current Water Control Plan (CWCP). MDC analyzed the channelized river from St. Louis, Missouri, to north of St. Joseph (river mile 476) using bathymetric data obtained from the COE in late-fall, 2001. This report, Technology Implemented Missouri River depth sounding data compiled by COE (Kansas City COE 2001) were interpolated to create a 3-dimensional representation of the Missouri River bed. In conjunction with water surface profiles also provided by the COE these data allow for estimation of depth at any given point in the river. Comparison of the water surface data with the river bed data yields depth estimates. Water depths were estimated and compared for two flows (the median CWCP flow of 57,200 cfs and the proposed 41,000 cfs at KC) for 476 miles of the lower river within the following four reaches: St. Joseph (110 miles), Kansas City (169 miles), Boonville (99 miles), and Hermann (98 miles).
