<br />~~ <br /> <br />~' <br /> <br />MEMORANDUM <br /> <br />TO: Bill Stanton, Bill Green, and File <br />FROM: John Van Sciv~v5' <br />DATE: March 16, 1995 <br /> <br />SUBJECT: Inspection of the Goodhue Ditch, owned by the Goodhue Ditch and Reservoir Co. <br /> <br />On March 16, 1995 Jan Illian and I met with the following people to observe the completed <br />repair of the Marshall flume, and to tour other problem areas on the Goodhue Ditch: <br /> <br />Mr. John Mayhoffer, President Goodhue Ditch. <br />Mr. Pete Johnson, City of Lafayette, Board Member Goodhue Ditch. <br />Mr. Rich Koopmann, Boulder Co. Open Space, Board member Goodhue Ditch. <br />Mr. Bob (Red) Pherson, Ditch Rider, Goodhue Ditch. <br /> <br />In 1994 the Company submitted an application for funding ($19,000) to repair the Marshall <br />flume, which was leaking badly. This authorization was included in the 1995 Construction Fund <br />Bill, with funds to be available summer 1995. However, because of the severity of the problem, <br />the company had to complete the repair in the fall of 1994. The repair cost the company about <br />$15,600, and consisted of a rectangular poured-in-place concrete flume, which replaced the <br />previous metal flume. The work appeared to be of good quality. <br /> <br />We toured the ditch, and inspected the following problem areas: <br /> <br />1) Approximately 1000 feet of ditch, located upstream of the Highway 93 crossing (at <br />about station 8 to 9), is on a steep hill and leaks badly. The preferred repair alternative may <br />be to place the ditch in a pipeline through this section. <br /> <br />2) The Miller Lateral Diversion weir at station 110 is deteriorated and undermined. The <br />ditch is being relocated and piped below this section by a developer, due to construction on <br />adjacent ground. The hope was that the weir could be replaced as part of this project, at nominal <br />cost. The developer will be relocating the pipe in the fall/winter 1995. <br /> <br />3) The Coal Creek Diversion Weir at station 151 is deteriorated and undermined. The <br />entire structure needs replacement. <br /> <br />4) The pipe under the road to the Lafayette Co-housing development (station 89) is set <br />too low. The result is that water backs up above the upstream invert, and trash tends to plug <br />the pipe. Remedies could include resetting the pipe, and/or cqncrete lining the ditch <br />downstream, in the area of stations 89 and 90. <br /> <br />The company feels that the most pressing problem is replacement of the Miller Lateral diversion <br />
