B. Water will be delivered on demand, modified by the designed capacity of the system and availability of the water.

Flow Restrictions

Excessively high flows through flow meters can cause damage to the District delivery systems when those flows are shut off. In order to protect the District property, deliveries by flow meter shall be limited to a maximum draw of 15 gallons per minute per assessed acre on any delivery where static pressures exceed 10 p.s.i.

Violation of this limitation will result in the installation of a restrictive orifice plate being installed by the District. The cost of installing such an orifice will be charged to the landowner and will become a part of the landowner's assessment. The charges for the installation of the orifice shall be established by the Board and shall be in an amount to recover all of the District's cost, including, but not limited to, materials, labor, supervision, equipment and overhead.

In the event of additional violations, water delivery to the landowner may be terminated, or at the discretion of the Board, a civil action may be commenced in appropriate superior court to obtain a restraining order to prevent violations of the rules. The District shall be entitled to recover its costs and attorney fees incurred to enforce these rules.

C. In times of shortage or rationing, whether it's district-wide, on a given lateral, pump or pipeline, each landowner will be given his proportionate share of the water available at that specific time and on a continuous flow proportionate basis. Any water rationed will be computed on the basis of current assessed acres.

D. Where a subdivision, or several small tracts of land, receives water from one Roza turnout the water delivery amount shall be computed as follows: the total yearly minimum delivery amount shall be divided by 200 days and this amount shall run continuously barring trouble in either the Roza system or the customer's system.

E. Based on an inherent policy of fairness and equality to all waterusers, requirements of State Law and the District Repayment Contract, no special consideration can be given to those waterusers wishing to use irrigation water for frost control. All water deliveries of the District shall be made in accordance with the existing rules and regulations of the District as published in the District Handbook, except as may be amended by subsequent Board action.

F. Damages to District Property

In the event any landowner purposely causes damage to any District-owned property, if appropriate, the District may file criminal complaint against the responsible parties. In addition the District shall recover the cost of repairing or replacing the property and the costs shall be added to the landowners assessment. The costs shall be established by the board and shall be in an amount to recover the entire District's cost, including, but not limited to, materials, labor, supervision, equipment and overhead.

In the event of additional violations, water delivery to the landowner may be terminated, or at the discretion of the Board, a civil action may be commenced in appropriate superior court to obtain a restraining order to prevent further violations of the rules. The District shall be entitled to recover its costs and reasonable attorney fees, incurred to enforce these rules.

G. Damages.  

If a Roza landowner uses District water for aquaculture or any purpose other than irrigation, such use shall be at the landowner's risk.  Landowners who use the District water for purposes other than irrigation shall indemnify and hold the District harmless from any damages, claims, losses or expenses which arise from such use of the District water.  District water may be treated with chemicals which are not compatible for uses other than irrigation.  It shall be the landowner's duty to contact the district for information concerning chemical treatments of District water.  Solely as a courtesy to District landowners, the District may maintain a list of persons who will be notified in advance of chemical treatments.  Provided, however, the District shall not be liable to any landowner for injury to persons, animals or property which may arise from the landowner's use of District water for any purpose other than irrigation, regardless of whether the landowner makes an inquiry to the District or whether or not the District provides notice of the chemical treatments to the landowner.

Treatment of Aquatic Vegetation

 In order to properly maintain the District’s canals and to deliver irrigation water, it will be necessary for the District to treat canals with herbicides to kill aquatic vegetation.  Aquatic herbicides may have adverse impacts upon the landowner’s crops or property. 

The District will notify landowners when the canal which supplies water to the landowner is treated.  Notice will be provided by the ditchrider, through the District newsletter or another method the District determines will provide notice to the landowner.  Landowners may contact the District office to obtain the District’s schedule for the application of aquatic herbicides. 

The District intends to use Endothall for control of aquatic vegetation.  The District, in its sole discretion, may use other chemicals or other methods to control aquatic vegetation.  Nursery stock may be susceptible to Endothall.  It shall be the responsibility of the landowner to control the use of treated water to avoid damage to the landowner’s crops or property.

 

(4)    WATER RIGHTS

The water right of the Roza Irrigation District is for up to 375,000-acre feet annually for irrigation of approximately 72,000 acres of land within the District. There are slightly more than 100,000 acres within the boundaries of the District with approximately 90,000 acres being classified as irrigable. By contract with the U.S. Bureau of Reclamation, the District may assess no less than 71,000 acres, and no more than 73,000 acres of the irrigable acreage. Removal of assessments or addition of assessments from any given parcel of land can only be accomplished as an action of the Board of Directors of the District, within the terms of the contract with the U.S.B.R.

(5)    RESPONSIBILITY FOR TAIL WATER DISPOSAL

The Manager shall shut off water whenever tail water is damaging District property, running unreasonable amounts of silt into the canal or laterals or making District roads or County roads impassable, or adversely affecting another wateruser. Whenever a water user has lands on both sides of a lateral he must pass his tail water across the lateral at his expense. The above tail water regulations apply equally to canals and laterals of the Roza Irrigation District and to those of adjacent irrigation Districts and to the County roads. For violations of this regulation from a water source other than the District, legal action may be taken to enforce compliance as defined in Regulation 3F.

(6)    PUMP PLANTS

A. Pumping plants will operate whenever the demand is high enough to operate a single pump safely.

B. Restarting Pumping Plants. No Roza Irrigation District pumping plant which has been off more than thirty minutes will be restored to service between 5 P.M. and 6 A.M.

(7)    LOCKING BOXES

Delivery boxes, turnout gates and flowmeters will be locked at all times.

(8)    FLOODED WEIRS

Every effort will be made to secure correct readings at flooded measuring devices, but it is the wateruser's responsibility for flooding and user must bear the possible loss of water. Water may be shut off if the water from the flooded weir interferes with lateral operation.

(9)    DISTRICT RIGHT-OF-WAY

A. Farming operations over pipe right-of-way are permitted, providing such operations do not damage or interfere with the routine operations and maintenance of said pipe. Routine repairs and maintenance, whenever possible, will be made in cooperation with the landowner, so as not to interfere with his operation. However, the District at all times reserves the right to enter upon said right-of-way to make any repairs and/or replacement it deems necessary.

B. If the farming operations damage the pipe, regardless of the amount of cover over said pipe, the landowner shall be liable for all damages, to include direct and consequential damages, and furthermore, shall be liable for any cost, fees or disbursements necessary to collect such damages.

The following will not be allowed except when explicitly authorized by the Manager.

A. Fences, bridges and pipe crossings across the canal and laterals and access roads.

B. Obstructions, including but not limited to buildings, equipment, debris, etc.

C. Birds and animals, etc.

(10)    CROSS-DRAINAGE CHANNELS

Culverts under canals and laterals must not be plugged by leveling or damming channel below so as to interfere with free flow of water in structure.

(11)    OUTLET DRAINS

The District may, at the request of the landowner, clean existing outlet drains, provided:

A. It is in the best interests of the District as a whole.

B. Time and funds are available.

C. Adequate right-of-way is provided.

D. Two or more Roza landowners are contributing surface flow to the drain.

(12)    COOPERATIVE PIPING

Whenever it is in the best interest of the District, time and funds permitting, laterals will be piped by District forces, provided, the landowner shall pay the cost of materials, required as determined by District personnel, and further provided, the landowner shall pay 100% of any blasting costs which may be necessary to facilitate said installation.
