<br />. <br /> <br />. <br /> <br />. <br /> <br />States to consider a similar resolution for the Lake Powell Pipeline that would deliver Upper Colorado <br />River Basin water to the St. George area in Virgin River Basin of Utah. <br /> <br />Ouray Floodplain Study: CWCB staff, FEMA and the Corps met with the Town of Ouray on Aug. 13. <br />We discussed completing the floodplain study after FEMA hired the Corps to update the Flood <br />Insurance Rate maps for Ouray. The Corps flood modeling program assumes all bridges and culverts are <br />blocked in a 100-year storm and an unlimited amount of debris and due to the steepness or the terrain <br />and the multitude of drainages the whole town was put back in the floodplain. <br /> <br />We have asked Larry Lang to help the town and FEMA by sorting out the bulking factor issues and <br />writing a letter to FEMA and the town that can correct certain assumptions because the Corps model <br />stacks the debris flow hydrograph and clear water flood hydrograph on top of each other to create high <br />peak flow numbers. <br /> <br />In actuality local newspaper articles and interviews with locals contend that for the 1927 and 1929 <br />storms, that were the worst on record, the debris flows came first then the clear water flood peaks shortly <br />thereafter. <br /> <br />The group also discussed the design and construction of a flood control feature on Skyrocket Creek. <br />The Board authorized $60,000 to the Town to build a new flood control feature to help direct flows out <br />ofthe Creek. The town has had a flood control feature there that has stood for 70 years but it is time to <br />rebuild it. The next step is for the town to produce a masonry design for the project for the CWCB <br />review in order to the loan. <br /> <br />Dolores River Floodplain Study: CWCB staff, FEMA and the Corps met with officials from <br />Montezuma County, the town of Dolores and local citizens on Aug, 13 to discuss the National Flood <br />Insurance Program. A local group, CF AR ("Citizens for Accountability on the River"), is still very <br />concerned about gravel pits and houses in floodplains and the accuracy of floodplain maps, There are a <br />few active gravel mines and 29 inactive mines. Sandy Rayl of the Corps mentioned successful Section <br />206 Ecosystem Restoration Projects have started with gravel pits because you already have a hole next <br />to the river and it is an opportunity to create a pond or wetland with inflow from and outflow to the <br />river. The county currently requires gravel operators to trees after mining is completed, <br /> <br />In the afternoon the group toured the area to see the gravel pits and housing situation. It was agreed that <br />a study 10-miles upstream of the town would be very useful for planning and floodplain management. <br />The next step is for the Mayor of Dolores to take the ideas and funding requests to the city council and <br />raise funding for a portion of this study and write a letter to the CWCB requesting funding, It was a <br />productive meeting and CWCB will work with FEMA to get a scope of work for aerial photography and <br />engineering in the fall. <br /> <br />Yampa River Basin Issues <br /> <br />Little Snake River Compact Update: Wyoming filed its response and motion to dismiss on April 19, <br />2002. A stay of all discovery has been granted until after the motions to dismiss are heard on October <br />16,2002. The Upper Colorado River Commission filed an amicus brief arguing that individuals in one <br />state lack standing to assert a private cause of action against another state, the signatory states are the <br />proper parties to enforce the interstate obligations under the compact. On April 8, 2002 Colorado sent <br />Wyoming a letter requesting that the two states get together and investigate the allegations made by <br />Three Forks Ranch. On Apri126, 2002 Wyoming responded back that they would be willing to take part <br />in such an investigation. Colorado and Wyoming met on May 30 in Cheyenne to initiate the <br />investigation and met again on August 2nd to continue that investigation. Wyoming hosted a tour of the <br /> <br />23 <br />
