-4- . Rick Miner - We are developing a river model from Denver to Nebraska to the state line. The modeling results will show flood stages all the way through Cobrado on the South Platte River . Brad Piehl- Recent flood impacts on the South Platte came from tributaries to the South Platte downstream of Chatfield, the model will show this fact . Larry Lang - the Urban Drainage and Flood Control District has nearly 100- year flood control protection through the City of Denver . Karen Sitoski - I recall that farms were flooded in Greeley in 1995 and they complained to the Corps . Rick Miner - These studies and work will give us what we need for an Environmental Impact Statement and feasibility study in the final report . Bill Doan - We have a decent reservoir operations model- using HEC 5 which is the standard for the Corps and is based on historic conditions. Weare calibrating it for the flood control. We calibrate by looking at upstream pool in wet years like 1980, 1983, 1995. We are now incorporating the Brown and Caldwell Storage Use Patterns Investigation Study information. Once we have existing conditions, then we look at impacts, upstream of the pool, the downstream disclnrge, release frequencies and flow durations. It's a daily flow model. The third impact is the Probable Maximum Flood. Using the 20,600 as conservation pool we then put the standard project flood on top to see impacts. We are modeling all three reservoirs as a system, release as quickly as possible, and account for incremental flows between the reservoirs. To elaborate on calibration of the simplified model, the Corps has developed rating curves. We are fine tuning the model . John Hendricks - In the Brown and Caldwell study we didn't have a good opportunity to show flexibility in terms of melding or optimizing operations with the conflicting interests . Leo Eisel- A major problem, gave up on this aspect of the releases, We can see if the results could be changed in uses and alleviate negative impacts . Marc Waage - We put in ideal operating scenarios but it would be nice if we had a chance to change them based on impacts to alleviate conflicts. Maybe we should build this into the schedule, do another iteration trying to optimize things, have regularly scheduled meeting we will have to work closely together, this is the initial input into the model . Brad Piehl - There are currently six different alternatives and six different operating scenarios, assuming we can gJ through a filtering process, move forward in the EIS need to figure it out then carry decisions forward through the EIS . Marc Waage - requested a line item in the Corps timeline that involves coordination . Polly Deitz - wanted to know monitors the Corps and water users in the new deal . Marc Waage - responded that the new operating scenarios will be part of the water control manual that will be designed and the state engineer will record how the water is released . Larry Lang - The state has a contract with the Corps for the existing 27,000 AF conservation pool. The state may enter into contracts with the water users after the reallocation study for the new storage space. The CWCB will hold public hearings to help make decisions about the reallocation among the water users. The 1979 contract between the Corps and the state has a nrovision that the state will conduct hearin"s on any future snace. The nrocedure has already been put in place . Rick Miner - The Corps is willing to put coordination with water users somewhere in the schedule before September 2006 so that the water people know when its going to happen. However, water discussions should be deferred for now because of what happened on the Bear Creek Reservoir Reallocation Study. Flood Protection. Water Project Planning and Finance.
