<br />Clterry Creek Probable Maximum Flood (pMF) Study: On October 20th the CWCB sent letters
<br />requesting that Colorado Congressional delegates Tom Tancredo and Joel Hefley grant approval for the
<br />U,S, Army Corps of Engineer's to move forward with the Cherry Creek PMF Study. On October 27th the
<br />two Congressmen sent letters to Colonel Jeffrey Bedey (Corps of Engineers) with the following
<br />instructions: I) approve $340,000 in federal funding for continuation of the study, 2) request that the
<br />Corps honor previous commitments and utilize the Site Specific Probable Maximum Precipitation (PMP)
<br />Study prepared by Applied Weather Associates in 2003, and 3) request that the Corps work closely with
<br />the Cherry Creek Advisory Committee and the CWCB during this next phase of work that focuses on the
<br />PMF study, This PMF study will be completed by the Corps in house, The Corps and the CWCB are
<br />developing a work plan and meeting schedule for the next year or two and will jointly host a kick off
<br />meeting in early February with the affected communities (Aurora, Greenwood Village, Douglas County,
<br />and Arapahoe County) and various experts, The ultimate goal in this process is to complete the PMF
<br />study and then develop dam safety improvement recommendations at Cherry Creek Reservoir that are
<br />acceptable to local, state, and federal interests.
<br />
<br />Corps SliD Concerned About Cherry Creek Dam: Questions remain about how well Cherry Creek
<br />Dam would withstand a catastrophic flood, though the dam is in no immediate danger, according to a new
<br />federal report, The flood-control dam's safety was first questioned in federal precipitation studies done in
<br />the 1980s and '90s, prompting the Army Corps of Engineers to suggest raising the dam. Homeowners and
<br />political leaders called the proposal ludicrous and the science on which it was based faulty, Rep. Tom
<br />Tancredo, R-Colo" and others stopped funding for the Corps' work on the safety issue in 1999,
<br />
<br />.
<br />
<br />Critics said a catastrophic flood resulting from a 500- or 1O,000-year storm was too remote a possibility
<br />to justify spending hundreds of millions of dollars and displacing homeowners and schools to prepare for
<br />such a stonn.
<br />
<br />In a recent report, the Corps said it was concerned about the failure to detennine whether the dam is safe,
<br />the Rocky Mountain News reported in Saturday editions. It also cited three other major concerns,
<br />A spillway that would direct water from the reservoir into nearby Tollgate Creek if there is a flood is
<br />deteriorating, the Corps report said. Work is on hold indefmitely until the overall dam safety issues are
<br />resolved, according to the Corps, The Corps also is concerned about deterioration of concrete walls on
<br />the dam's outlet works, The problem hasn't been repaired, though the deterioration was discovered in
<br />200 I.
<br />
<br />Last month, the Corps was authorized to spend $340,000 to run a flood analysis and to determine
<br />conclusively whether the dam will have to be fixed, Corps officials said they hope to determine what
<br />needs to be done by September 2007.
<br />
<br />Chatfield Reservoir Reallocation Study: The Chatfield Reservoir Reallocation Group has met on a
<br />regular basis through the end of 2005 and plans to meet again in January 2006 to continue discussions and
<br />progress updates on the overall study process, To recap, the fundamental scope of the study is to look at
<br />the feasibility of converting flood control storage space in Chatfield Reservoir, owned by the U,S, Corps
<br />of Engineers (Corps), into water supply storage space, The target amount of space for the reallocation
<br />analysis has been 20,600 acre-feet, and the Corps has announced that the Antecedent Flood Study has
<br />been finalized and accepted by the peer review committee. Final endorsement by the highest levels of
<br />Corps officials will confinn the expected storage volume that can be considered for water supply,
<br />
<br />.
<br />
<br />The expected storage allocation has been prorated among 16 water users and they have been grouped into
<br />what is known as the Upstream and Downstream users, The Upstream group consists of water users in the
<br />southern Denver Metro area including: Parker W &S, South Metro Water Supply Authority, Centennial
<br />W &S, Castle Rock, Roxborough Metro District, Castle Pines Metro District, Castle Pines North Metro
