DITCH CLEANING Clause Examples

DITCH CLEANING. The open irrigation ditches on NB Ranches, Inc. are prone to vegetation growth, which slows the conveyance of water and clogs the buried mainlines, leading to ditch loss and reduced diversion volumes. The ditches need to be cleaned yearly to remove vegetation and repair breaches. Cleaning ditches consists of mechanical cleaning with a backhoe once or twice per year, Typically during non-irrigation season. Some work may occur during the late summer months (August and September) if aquatic vegetation growth is significant The ▇▇▇▇▇▇▇ diversion intake is maintained by an 8' diameter self-cleaning fish screen (Cone Screen). Operation and maintenance can entail the use of heavy equipment at the point of diversion to remove spoils and deposited sediment to maintain channel design elevations. Ditches, field checks and tail water prevention berms are impacted through livestock trampling and require rebuilding and re-grading using tractors and heavy equipment to maintain their function. This work occurs as needed but work is conducted annually focusing on problem areas. The ▇▇▇▇▇▇▇ fish screen is an 8' diameter self-cleaning cone screen. The ▇▇▇▇▇▇▇ screen has not experienced any significant sedimentation issues since installation; however this may be required in the future. The brushes generally need to be replaced on a cone screen every five years. Maintenance and operation responsibilities are accepted by NB Ranches, Inc. and the other ▇▇▇▇▇▇▇ users. NB Ranches, Inc. has 7 distinct pastures where cattle graze. Cattle are rotated through the pastures as part of pasture management. The cattle are moved when grass height is reduced to 3-5 inches in height throughout the irrigation season. NB Ranches, Inc. has a bridge crossing of the Shasta River connecting fields on the West side of the River with fields on the East. The approaches and footings require repair and replacement after flood events, including instream work at times. The riparian corridor is fully fenced except for approximately 1,600' of the west river bank located near the northern boundary on the western side of the river. An additional 1,200' located immediately south of that would benefit from repair or replacement. NB Ranches, Inc. intends to exercise continued limited riparian grazing. The Enrolled Property maintains the riparian fencing and will continue to maintain riparian fencing but does not accept the financial responsibility of repairing loss from major floods where 25% of the fence or gre...

DITCH CLEANING. Developer shall comply with all requirements set forth for drainage into any county ditch or other ditch through which water from Said Plat may drain, and shall make any necessary improvements or go through any necessary procedures to ensure compliance with any federal, state, county or Town requirements, all at Developer's expense.

DITCH CLEANING. The conveyance ditch from the diversion to the place of use has significant aquatic plant growth; the Permittee cleans the vegetation out of the conveyance ditch at least annually with a weed mower. The open ditches are prone to excessive algae growth, which slows the conveyance of water. The Permittee cleans the ditches at least yearly to remove vegetation and fix breaches. The Permittee will continue to clean ditches until the Beneficial Management Activities are implemented and this is no longer necessary. Most of the ditches will be replaced with buried pipeline (see Section E.2.a) as a result of this Site Plan Agreement and then pipeline cleanouts will be opened monthly to flush any vegetation out to ensure proper conveyance in the pipe network. The flashboards on the existing diversion become blocked by beaver activity, making the flashboards challenging to remove. They then need to be periodically removed using heavy equipment to open the diversion. This will continue in the interim until the point of diversion is relocated (see Section E.2.b).

DITCH CLEANING. The open irrigation ditches are prone to vegetation growth, which slows the conveyance of water and clogs the buried mainlines. The ditches need to be mechanically cleaned at least yearly to remove vegetation and repair breaches, by using a backhoe. Irrigation ditch maintenance cleaning is required annually, at a minimum, and as needed throughout the irrigation season. Annual diversion dam construction: Permittee diverts water using hand piled cobble or gravel push-up dams to annually construct diversion impoundments to increase water surface elevation to allow for diversion. Enrolled Property’s diversions #1 and #2 typically require use of a back-hoe to construct impoundments that begin initial impoundment work as flows reduce during late spring. The impoundment at #1 is extended across a portion of the wetted channel as flows decline through the summer. Diversion structures at diversion points # 3, #4, #5 and #6 are typically constructed by hand unless winter high flows have caused significant alterations. At times tarps are used in combination with hand constructed or equipment constructed impoundments. The timing of when the diversion work is conducted is dependent on flow volume, need for irrigation and damage resulting from high flows during the previous winter. Diversions #1 and #2 require the POD to be opened by removing some larger rock and bedload material which is placed in the head of the diversion the previous fall to prevent high flows from entering the diversion. Initial diversion typically just requires removal of material from the head of the diversion ditch rather than impounding the stream. No impoundment is necessary until typically late May. Late May is also typically when hand work is done at diversion points #3, #4, #5 and #6. Fish passage is provided using an opening at least 1.0' wide with several inches of water passing through/over the diversion structure during base flows. Spring Creek system is primarily operated at a reservoir (diversion #202). The other diffuse sources of Spring Creek feed into established ditches and eventually drain to Parks Creek approximately .5 miles below the MWCD diversion from Parks Creek. Spring Creek system does not have a channel or annual scour but does connect to Parks Creek delivered via a grass dominated swale. The natural rock riffles at the diversion structures and the head gates can become clogged with debris or blackberries. They need to be periodically cleared mechanically to ensure proper...
