e e e geomorphological problems in the Capulin subreach and upstream aU the way to Terrace Reservoir has been completed. The project engineer began the design process in June 2003. Once the design has been finalized, construction will begin. The project wiU also address maintenance and monitoring. The project is expected to be completed during the 2004-05-construction season. 3. Chatfield Reservoir Reallocation Study Authorization: HB 98-1189 Grant Amount: $266,094 Water Source: South Platte River Project Type: Reservoir Supply Study Location: 10 miles S. of Denver Project Manager: Larry Lang Sponsor: CWCBfU.S. Army Corps of Engineers Beneficiary: Colorado Water Users This project involves cooperating with the Corps of Engineers to complete a feasibility study regarding the reaUocation of existing flood control storage to a multi-purpose use. The CWCB is investigating the opportunities and feasibility for the reaUocation of certain storage volumes. The project will determine reaUocation opportunities and impacts, environmental assessments, produce recommendations, and formalize a request to higher Corps authority. Three significant developments happened in FY02-FY03. (I) The CWCB hired Brown and CaldweU and completed a Storage Use Patterns Investigation study with aU water users with a viable interest in Chatfield Reservoir (2) Simons and Associates was terminated by the Corps of Engineers for not meeting study performance objectives and the main subcontractor for the study Foster Wheeler - TetraTech was hired as the main contractor and (3) CWCB worked with state parks to hire EDA W of Fort Collins to perform a "Recreation Facility Mitigation Study" that will be completed by December 2003. Development (I) was the cooperation that occurred among the water providers in the Storage Use Patterns Investigation Study. Brown and CaldweU developed operational plans for proposed 20,600 Ac.-Ft. storage space and produced r.outing scenarios in concert with actual water users for municipal use, agricultural use, wildlife and recreational use and conjunctive use patterns. This study provided actual use patterns and was based on the Denver water PAXSON model at Chatfield Reservoir. A final study was produced and is on the CWCB website. Letter of support of the ReaUocation Study and Storage Use Patterns Investigation Study were produced and included in the appendix ofthis report. Development (2) involved poor contract performance by Simons and Associates. The Corps tried to work with Simons repeatedly on revising schedules and delivery dates but in the end a work model for the reservoir and downstream and a series of technical memorandums was not produced. However the performance and products were satisfactory by the subcontractor to Simons and Associates, Foster Wheeler Environmental Corp now Foster Wheeler - Teratech. Foster Wheeler Tetratech negotiated a contract for approximately $670,000 to continue as the main contractor in Spring 2003. The main study will await completion of the Recreation Facility Impacts Study and start up again in faU2003. The CWCB used the As Needed Program to hire EDA W Fort Collins to complete a Recreation Facility Impacts Study. EDA W will be responsible for resource facility analysis and mapping; defining alternative concepts; putting costs to the replacement and mitigation for recreational amenities; and preparing a draft mitigation plan complete with two alternative schematics of the replacement of facilities above the anticipated 12 foot increase in daily operational levels at the completion of the study. This study is slated for completion in December 2003. 4. Floodplain Mappinl!
