at sites chosen by Whooping Crane are compared to conditions upstream and <br />downstream, at sites not chosen. The original HECRAS model had 920, primarily <br />interpolated, cross sections spaced every one-tenth of a mile. The 2001 HECRAS model <br />was stripped and re-constructed primarily through the elimination of many interpolated <br />cross sections, and in some cases the addition of copied or constructed synthetic cross <br />sections. Copied or constructed cross sections were chosen to reflect general geometry of <br />the river reach in the vicinity of the cross section. The re-constructed base model contains <br />170 cross sections spaced approximately every one-half mile. We think the re-constructed <br />base model and selected cross sections will provide more representative information on <br />the main channel for the requirements of this analysisl. The need to reconstruct the <br />existing Platte River HECRAS model was not anticipated and delayed us approximately <br />four days. <br />Schedule and Deliverables <br />The 2001 HECRAS model is nearly complete and preliminary output tables will be <br />provided to Shay Howlin of WEST on the first day of the next reporting period (March <br />3). Construction of the geometry file for the 2002 HECRAS model is nearly complete so <br />the output tables for 2002 will be provided in the next period. We would also like to <br />provide output tables for 2003, 2004 and 2005 in the next period. There is a small number <br />of WC observations and transect data associated with these years. Due to the need to re- <br />construct the HECRAS Platte River model (base cross sections), we are approximately 4 <br />days behind schedule. <br />Action Items <br />Reclamation will be seeking feedback from Shay Howlin at WEST on the 2001 output <br />tables, to determine if any changes are needed for the 2002- 2006 output tables. <br />The fourth and last scheduled progress report on Phase II of the Whooping crane Data <br />Analysis will cover efforts from March 1, 2008 to March 14, 2008. <br />' Caurion- using the model "as is" for applications different from this analysis, i.e. flood studies, could <br />produce less accurate results. <br />Progress Report 3 2 Phase II Whooping Crane Data Analysis
