(2) If the owners of any such irrigation ditch, canal, flume, or reservoir fail or neglect to erect or maintain in good repair said headgate, measuring flume, weir, or devices, in the manner and form provided in this section, then the state engineer or division engineer, upon ten days' previous notice in writing, duly served upon such owners, or upon any agent or employee representing them or controlling such ditch, canal, flume, or reservoir, shall refuse to deliver any water from such stream to such owners, or to such ditch, canal, flume, or reservoir, until such owners erect or repair the headgate, measuring flume, weirs, or devices of such ditch, canal, flume, or reservoir. The owners of all such ditches, canals, flumes, or reservoirs shall be liable for all damages resulting from their neglect or refusal to comply with the provisions of sections 37-84-112 to 37-84-117. Such owners who divert water from any such stream and into any such ditch, canal, flume, or reservoir contrary to the orders of the state engineer or division engineer are guilty of a misdemeanor and, upon conviction thereof, shall be punished by a fine of not more than five hundred dollars, and each day of violation shall be deemed a separate offense.

C.R.S. § 37-84-113 Measuring flumes - construction

37-84-113. Measuring flumes - construction. The owners of any irrigation ditch, canal, or reservoir, transferring water from one natural stream to another, or from a reservoir, ditch, or flume to a stream in order that said water may be diverted from such stream for irrigation or any other purpose, shall construct suitable and proper measuring flumes or weirs, equipped with self-registering devices if required by the state engineer, for the proper and accurate determination of the amount and flow of water turned into, carried through, and diverted out of said natural stream. If the owners of any such irrigation ditch, canal, or reservoir fail or neglect, upon five days' previous notice in writing duly served upon them or their agent or employee, to erect, maintain, or repair such measuring flume, weir, or device, the state engineer or division engineer shall refuse to allow to be taken or diverted from any stream any water whatever on account of delivery of water to such stream, for such time and until such owners cause to be erected or repaired such flumes, weirs, or devices, at the point of delivery to and taking from said natural streams so used as a conduit.

Nothing in sections 37-84-112 to 37-84-117 shall be construed as prohibiting any water user in the state of Colorado or his appointed agent from reading any gauge, gauge rod, or measuring device or from determining the quantity of water diverted by any canal or impounded in or delivered from any reservoir, and it is here declared the intent and purpose of sections 37-84-112 to 37-84-117 to give any water user of Colorado or his appointed agent the right of ascertaining the quantity of water being diverted by any canal or impounded in or delivered from any reservoir without his being required to assign any reason for making such observations. Noncompliance with the provisions of sections 37-84-112 to 37-84-117 shall, during such noncompliance, forfeit the right to divert water into any canal or to impound water in or deliver water from any reservoir.

C.R.S. § 37-84-117 Reservoirs in streams

37-84-117. Reservoirs in streams. (1) The owners of any reservoir located upon or in the bed of any natural stream or through which any natural stream flows, for the purpose of storing or diverting water, at the expense of the owner, shall furnish a complete survey of the contour lines of the reservoir for the state engineer's approval. Alternatively, in the discretion of the state engineer, a survey of the contour lines of the reservoir shall be made under the supervision of the state engineer, the deputy state engineer, or the division engineer of the division in which the reservoir is located. Contour lines must be ascertained for at least every vertical foot in depth and, where deemed necessary by the state engineer, for fractions of a foot. The owners of any reservoir shall prepare a table to be filed with and approved by the state engineer, showing the capacity, in cubic feet, for each foot in depth or fraction of a foot in depth of the reservoir. The owners of the reservoir shall file a copy of the table with the division engineer in whose division the reservoir is located. All maps, plats, field notes, tables, and surveys for a reservoir shall be filed with and approved by the state engineer and remain a part of the records of the state engineer's office. (2) The owners of a reservoir described in subsection (1) of this section, at their own expense, under the supervision and with the approval of the state engineer, shall permanently fix and maintain a gauge rod or other instrument, or both, as directed by the state engineer, to measure the surface elevation of the reservoir at or near the outlet of the reservoir, marked in feet and tenths and one-hundredths of a foot, and in correspondence with the contour lines, from and by means of which the amount of water stored in the reservoir may be correctly ascertained. The owners, at their own expense, and under the supervision and with the approval of the state engineer, shall construct and permanently maintain a suitable and permanent measuring structure equipped with self-registering devices, according to plans and specifications approved by the state engineer, either in the bed and channel of every natural stream or watercourse discharging waters into the reservoir or on each release from the reservoir by means of which, in combination with the amount of water stored, all of the water flowing into the reservoir from the natural stream or watercourse may be definitively ascertained and determined at all times. (3) (a) Any instruments or structures described in subsection (2) of this section are subject to inspection at all times by the owner or duly authorized agent or representative of the owners of any appropriation of water from the stream upon or in which the reservoir is constructed or operated. (b) The state engineer or division engineer may refuse to allow any water to be taken into or diverted from a reservoir if: (I) The owners of the reservoir fail to construct or permanently maintain any required instruments or structures, equipped as described in subsection (2) of this section; or (II) Except as specified in subsection (3)(c) of this section, within thirty-five days after the state engineer or division engineer has provided written notice to the owners or their agents or employees directing the owners to make a contour survey, as described in subsection (1) of this section, the owners fail to cause a complete survey of the contour lines of the reservoir to be made. ion; or (II) Except as specified in subsection (3)(c) of this section, within thirty-five days after the state engineer or division engineer has provided written notice to the owners or their agents or employees directing the owners to make a contour survey, as described in subsection (1) of this section, the owners fail to cause a complete survey of the contour lines of the reservoir to be made. (c) If suitable instruments and structures have been installed and equipped and the owners, their agents, or their employees are making good-faith efforts to complete the contour survey, the state engineer and division engineer may allow water to be stored in any such reservoir after the expiration of the thirty-five days notice as described in subsection (3)(b)(II) of this section. (4) If the state engineer or a division engineer receives from the owner of a water right appropriating water from a stream upon which a reservoir is located, or a stream that is tributary to such a stream, a complaint alleging facts against the owner of the reservoir that, if true, would amount to a violation of this section, the state engineer or division engineer shall investigate the complaint and, if the allegations are found to be true, shall enforce this section. (5) The state engineer may order that an owner of a reservoir release an amount of water from the reservoir that, in the determination of the state engineer, is necessary to prevent evaporation on the surface of the reservoir from depleting the natural flow of the stream running through the reservoir that would otherwise be available for use by other appropriators. In determining the quantity of any evaporation release under this section, the state engineer shall compute the surface evaporation from the reservoir and deduct from the surface evaporation any accretions to the streamflow resulting from the existence of the reservoir and any natural depletions to the streamflow that would have resulted if the reservoir were not in existence.

C.R.S. § 37-84-118 Ditch owners to provide flow - when

37-84-118. Ditch owners to provide flow - when. Every person or company owning or controlling any canal or ditch used for the purposes of irrigation and carrying water for pay, when demanded by the users from April 1 until November 1 in each year, shall keep a flow of water therein, so far as may be reasonably practicable for the purpose of irrigation, sufficient to meet the requirements of all such persons as are properly entitled to the use of water therefrom, to the extent, if necessary, to which such person may be entitled to water and no more. Whenever the rivers or public streams or sources from which the water is obtained are not sufficiently free from ice, or the volume of water therein is too low and inadequate for that purpose, then such canal or ditch shall be kept with as full a flow of water therein as may be practicable, subject, however, to the rights of priorities from the streams or other sources, as provided by law, and the necessity of cleaning, repairing, and maintaining the same in good condition.

Any division engineer, or the division engineer's deputy or assistant, who willfully neglects or refuses, after being called upon, to promptly measure water from the stream or other source of supply into the irrigating canals or ditches, in the division engineer's division, according to their respective priorities, to the extent to which water may be actually necessary for the irrigation of lands under such canals or ditches commits a petty offense.

C.R.S. § 37-84-123 Jurisdiction of county court

37-84-123. Jurisdiction of county court. In all cases declared misdemeanors by sections 37-84-118 to 37-84-123, the county court of the county in which the offense was committed has jurisdiction.

C.R.S. § 37-84-124 Amount of water taken

37-84-124. Amount of water taken. It is the duty of every person who is entitled to take water for irrigation purposes from any ditch, canal, or reservoir to see that he receives no more water from such ditch, canal, or reservoir through his headgate, or by any ways or means whatsoever, than the amount to which he is entitled. At all times, such person shall take every precaution to prevent more water than the amount to which he is entitled from such ditch, canal, or reservoir from coming upon his land.

C.R.S. § 37-84-125 Receipt of too much water

37-84-125. Receipt of too much water. It is the duty of every such person, taking water from any ditch, canal, or reservoir, to be used for irrigation purposes, on finding that he is receiving more water from such ditch, canal, or reservoir, either through his headgate or by means of leaks, or by any means whatsoever, immediately to take steps to prevent his further receiving more water from such ditch, canal, or reservoir than the amount to which he is entitled. If knowingly he permits such extra water to come upon his land from such ditch, canal, or reservoir, and does not immediately notify the owners of such ditch or take steps to prevent its further flowing upon his land, he shall be liable to any person, company, or corporation who may be injured by such extra appropriation of water, for the actual damage sustained by the party aggrieved. The damages shall be adjudged to be paid, together with the costs of suit, and a reasonable attorney's fee to be fixed by the court and taxed with the costs.
