INTRODUCTION <br />The goal of this project was to reconstruct the irrigation diversion stricture that consisted <br />of an open ditch, without a head gate, and apush-up gravel dam that prevented fish <br />migration and safe boat passage; the diversion also caused a section of the river to be <br />completely dried up during low water. The lack of a head gate resulted in the ditch being <br />occasionally washed out during high water, adding additional sediment to the river. <br />A Colorado Watershed Protection Fund grant, originally allocated for reconstruction of <br />the Stewart Ditch diversion (a similar project), was re-allocated to this project when <br />disagreement with the Stewart Ditch Company prevented that project. Additional funding <br />was provided by the Delta Conservation District and the Bureau of Reclamation. In-kind <br />donations of boulders and heavy equipment operating time were donated by the <br />Vandiford Ditch shareholders. <br />PROJECT GOALS, OBJECTIVES, and ACTIVITIES <br />Planned and Actual Milestones, Products and Completion Dates <br />TASK 1: Project evaluation and erzgirzeeriug and construction layout. <br />Products: Survey, Environmental Impact <br />Analysis and construction plans and <br />specifications. <br />Cost: $21,000. Field survey, aerial photography, <br />and environmental analysis were donated by the <br />U. S. Army Corps of Engineers. The value of the <br />donation is $11,000. Constriction plans and <br />specifications were developed by Crane <br />Associates at a cost of $10,000. <br />Completed: October 2007. <br />~. > . <br />,= <br />~ ~ ~M' <br />` <br />~ <br />~.>~ ° ~ , <br />,,~~pp~~ . <br />~ <br />. ~ ~,~ ~,. <br />'' <br /> ~,~: <br /> <br />•~~ ~~: <br />#~ <br />.n` <br />~ y <br />-r, I <br />:: X.. <br />~- ~; ~~» <br />`~ u <br />~_~ ~,~ <br />~ <br />.. <br />!, ~ c ,r ~ ° ~, .c z { <br /> <br />A' <br />~3 <br />~ <br />1ry. <br />1 <br />t W j. ~ <br />~. p~} <br />'t ~~ li .~~ ~ ~ <br />; <br />~ 5 <br />~ <br />~ <br />. ~~ <br />~ <br />TASK 2: C'oy~str~rctiou. <br />Products: Mobilize equipment, haul boulders, control water, excavate for pipe, <br />headwall, head gate and channel diversion. Construct and grout concrete head wall, <br />install 24 inch metal gate with control valve, 100 feet of 24 inch galvaiuzed CMP <br />pipe in ditch. Baclcfill and compact around strictures with 3,555 cu yd gravel. Bai~lcs <br />were smooth and back-sloped. Riprap placed around stricture and ditch bail{ with <br />600 cu yd boulders. Construct rock veins to protect banks and divert water flow to <br />head gate. Remove 7,000 cu yd gravel from push up dam. <br />Cost: $46,826 <br />Completed: December 2007 <br />
