<br />- 3 - <br /> <br />the Reallocation Project. CWCB indicated that conservation was looked at very carefully in the SWSI <br />study, and water supply projections using the highest level of conservation still left a large unmet need by <br />2030 for the South Platte basin. <br />. The Corps and Tetra Tech are nearing completion ofthe "Purpose and Needs" Section and then it will <br />become part ofthe Preliminary Draft Report/EIS. Tetra Tech and the Corps will have to work out plans for <br />distributing Preliminary Draft Report/EIS products to the Chatfield Study Group for review and comment. <br />The Report/EIS will not be available for public review until it is in Draft form and released. <br /> <br />Environmental Restoration & WRDA Bill Status (Denver) <br />. Terry Baus stated that Denver is optimistic that the WRDA bill will go through in November. There are 47 <br />states that want their projects authorized that were not affected by Hurricane Katrina. The original WRDA <br />Bill proposed language that creates a nexus between Chatfield Reallocation and environmental restoration. <br />Denver has been in contact with Diana DeGette and Ken Salazar, but one of the Congressional staff <br />members strongly recommended that revisions to the restoration add-on language should not be done. The <br />specific revisions were originally suggested by Aurora and endorsed by the CWCB. The Chatfield Study <br />group endorsed the revisions as well, but they ultimately were not included in the WRDA bill. <br /> <br />Downstream Water Users Group (Denver Water) <br />. The Group is moving ahead to form a technical committee to look at potential benefits of environmental <br />restoration. Their kick off meeting will be October 20th. They will meet at Denver Water in room 308 at <br />10:00 AM. This meeting is for the technical committee only with representatives from the DOW, UDFCD, <br />CWCB, and other subject matter experts. Others are welcome to attend to observe, but this is not a public <br />meeting. <br />. The group will look at the studies done through the Mayor's South Platte Commission in the 1990s and see <br />what can be used. <br />. A multi-agency meeting will be scheduled later to review existing data and identify potential benefits. <br />There will be a field tour of the study reach for the Corps as part of this meeting to show reaches that would <br />benefit from the potential releases. Sometimes there is 1-2 cfs flowing in the river, with an opportunity for <br />10-15 cfs during certain time periods as a result of the Chatfield releases. The Corps has suggested a study <br />analysis outline. The Chatfield Study Group is checking to see if some of that work has already been done. <br />. Rick McLoud stated that the reservoir operational estimates have been revised to not include strategic <br />releases. The new reservoir inflow and outflow estimate does not greatly change recreational or <br />environmental impacts (see attachment) on the reservoir. The new fluctuations were sent to Paul Flack and <br />to the Corps modelers. <br />. Doug Clemetson stated that the model is set up and they have been making runs and changing target flows <br />downstream. The Corps is not sure what the schedule is to finish the work, but anticipate that the work will <br />be done by the end ofthis calendar year. The Corps needs to look at different target capacities and develop <br />stages of probability curves for Bear Creek, Cherry Creek and Chatfield. Changes in the flow frequency <br />and flow duration need to be evaluated as well. This characterizes how storage will impact downstream <br />issues, and will get at the physical circumstances for environmental, flood control, and recreation concerns. <br /> <br />Recreation Miti2:ation Study Phase II (State Parks) <br />. EDA W is under contract with State Parks, and a kick -off meeting was recently held to discuss Phase II of <br />the Recreation Study. <br />. The Phase I Study is posted on the CWCB web site and primarily looked at relocating facilities above the <br />maximum target storage pool of20,600 AF (above elevation 5444) with an additional two feet to account <br />for wave action. <br />. The Phase II Study will use the information generated by the Water Users for the Corps Reservoir routing <br />model to determine the fluctuations. Currently, State Parks works with 9 feet of fluctuations from Denver <br />Water's operations. The proposed reallocation may cause fluctuations of21 feet (elevation 5444 - 5423) <br />based on the needs and uses of the water users. <br /> <br />Flood Protection.
