. . . It should be clearly understood that the northern terminus of the District's maintenance responsibility for what is described in the report as the West Douglas Wash - Main Channel has historically been the Price Ditch. There is an 18" RCP under the Price Ditch at that location which was replaced cooperatively by the Palisade Irrigation District and the Drainage District. That 18" RCP replaced an 18" CMPI What is identified as West Douglas Wash. Reach 1W is not a part of any system under the jurisdiction or authority of the Drainage District. What is identified as West Douglas Wash .Reach 1 E is not a part of a system under the jurisdiction or authority of the Drainage District. East Douglas Wash - Main Channel from a point south of HWY 6 (sta 27+20) is maintained by the District and known as the WATERBRIDGE DRAIN. The reaches upstream of the HWY are not considered a part of the Drainage District system. The drain was named for an old wooden structure which carried surface and subsurface water over the Grand Valley Irrigation Company Canal in a wooden flume from sta 19+65 to sta 20+35. That "waterbridge" WllS replaced in the 1960's with the present inlet, vertical drop to the large diameter pipe under the GVIC canal. The trash rack on the upstream side of the GVIC canal is one of the grates checked and cleaned twice a week by Drainage District personnel. The downstream structures are a mixed responsibility, some are Mesa County Road and Bridge Department structures some are GJDD / private facilities for field access. The winding channel to the Colorado River is maintained by the Drainage District with frequent and rather severe competition from beaver. Amendment 14, the trapping Dan, has negatively impacted the District's ability to maintain an open channel with assured capacity. What is identified as East Douglas Wash - North Branch is partially operated and maintained by the District as the NORTH WATERBRIDGE DRAIN. There is a mixture of open and piped sections of the portion of the system that is under District responsibility between sta 1 +60 and sta 8+75, the south side of the US Gov't Highline Canal. There is a pipe under the Price Ditch and several others which are small but present. The pipes were installed during a time period when the District had been advised by competent legal counsel that the District had to transport only seep water (subsurface drainage) and return flow irrigation water. Collection and/or transportation of storm water / surface runoff was definitely not the purpose of the Drainage District. The District is willing to provide all known information concerning conveyances in the basins that would affect the calculations and maps within this report.
