<br />. <br /> <br />. <br /> <br />. <br /> <br />MEETING SUMMARY <br />Weldona Flood Hazard Mitigation <br /> <br />December 29, 1997 <br /> <br />Overview: <br /> <br />On Monday, December 29, 1997 a meeting and site visit were held in Weldona to discuss flood <br />hazard mitigation for the community. The CWCB and WRC Engineering met with local <br />officials and a landowner to review alternatives, share ideas, view proposed mitigation areas, and <br />document the 1997 flood characteristics. <br /> <br />Meeting Attendees: <br /> <br /> <br />ltfd! <br />Darrell Graham <br />Dick Earl <br />Don Christensen <br />Tom Brownin <br />Alan Leak <br /> <br />Key Results: <br /> <br />The following bullet items summarize the key results of the meeting and site visit: <br /> <br />Flood Documentation (Flood event of J ulv 29/30. 1997) <br />. The three existing reservoirs in the lower Schaefer Draw watershed (located in Section 27 <br />and 22) did not fail during the flood. The reservoirs filled and spilled, but damage to the <br />dams did not occur according to the landowner. The three reservoirs were viewed during the <br />site visit. The uppermost reservoir Gust south of the Riverside Canal) is located on State- <br />owned land, while the lower two are located on private property. The upper reservoir had a <br />storage capacity of about 75 acre-feet prior to the flood. That reservoir may have less flood <br />control capacity now due to the sediment loading that was washed into it during the flood. <br />The lower two reservoirs have less capacity than the upper one. The existing dams were <br />privately built (many years ago) for the purpose of flood control and irrigation. <br /> <br />. The CWCB estimated a peak flow of about 1300 cfs on Schaefer Draw above the Riverside <br />Canal. The landowner estimated that the flow was double that amount just below the <br />Weldon Valley Ditch flowing to Weldona. <br /> <br />. Flow from County Road 8 (fairly large watershed to the west of Schaefer Draw) emptied into <br />the Weldon Valley Ditch at the location where the ditch crosses the road. The Weldon <br />Valley Ditch was overtopped by as much as 2 feet between County Road 8 and County Road <br /> <br />----- - ------ <br /> <br />-....... <br />
