Plain English Breakdown
The official summary does not specify exactly how 'site-specific criteria' will be determined, only that a procedure for their identification is implemented.
Revegetate or Dry Farm Formerly Irrigated Agricultural Land
This law requires water right owners in Water Division 2 who stop using their water for farming on or after January 1, 2027, to plant new vegetation or switch the land to dryland farming with erosion control and weed management.
What This Bill Does
- Requires revegetation or conversion to dryland farming with effective erosion control and weed management when a water use change occurs in Water Division 2 on or after January 1, 2027.
- Establishes site-specific criteria and scientific methods to measure the success of these land changes.
- Orders the water court to appoint an expert for annual field reviews until the new vegetation or farming method is successfully established.
- Allows the water court to require financial assurance from owners to cover costs if revegetation fails, place limits on when or how much water can be used during the transition, or incorporate existing permit requirements into the final decree.
Who It Names or Affects
- Water right owners in Water Division 2 who change their water use from agricultural irrigation to another beneficial use on or after January 1, 2027.
- The state water court responsible for appointing experts and issuing orders regarding financial assurance or usage limits.
Terms To Know
- Water Division 2
- A specific geographic area where this law applies to changes in water rights use.
- Dryland farming
- Farming methods that do not rely on irrigation, used here as an alternative when stopping agricultural irrigation.
- Financial assurance
- Money provided by the owner to cover anticipated costs if successful revegetation is not achieved.
Limits and Unknowns

L.001
HOU Agriculture, Water & Natural Resources
Passed [*]
Plain English: This amendment requires water right owners in Colorado's Water Division 2 who stop irrigating farmland after January 1, 2027, to replant vegetation or switch to dry farming and prove they are managing weeds.
- Water courts must include rules for planting new crops or switching to dry farming when approving changes from irrigation water use starting in 2027.
- Owners must create a plan with specific scientific methods to measure if the land is successfully replanted and how they will control weeds using mowing, chemicals, or other approved ways.
- A neutral expert hired by the owner must visit the fields every year to check progress and report exactly what percentage of the land has been successfully restored.
- Once the land is fully restored, a five-year maintenance period begins where the owner must keep the vegetation healthy before final approval.
- The official text provided ends abruptly in the middle of a sentence regarding the final maintenance report details.
- Specific costs for hiring experts or exact penalties for failing to meet these requirements are not detailed in this amendment section.
L.002
HOU Agriculture, Water & Natural Resources
Passed [*]
Plain English: This amendment changes a phrase in the bill to specify that something must be approved by an authority.
- The text on page 2, line 38 is changed from its previous wording to say 'APPROVED BY THE'.
- The amendment only shows the new words and does not show what was removed or who exactly must give approval.
- Because the full sentence context is missing, it is unclear how this change affects water right owners changing their land use.
L.003
SEN Agriculture & Natural Resources
Passed [*]
Plain English: This amendment sets specific yearly deadlines for reporting, gives the Water Court power to limit water use if land restoration fails or requires extra oversight if it might fail later, and adds a rule that owners must provide money guarantees before starting.
- Sets new annual deadlines requiring reports by November 1 and owner actions by December 1 each year.
- Allows the Water Court to reduce how much water can be used for new purposes if land restoration or dry farming is not successfully completed over time.
- Gives the court authority to add extra, temporary monitoring periods even after success if there is a high risk that the restored land will fail in the future.
- Requires owners to provide financial guarantees covering the full cost of restoring vegetation before they can begin.
- The provided text cuts off mid-sentence while defining what 'successfully established' means, so the exact definition is unknown based on this material alone.
- Some technical legal references to specific state code sections are included but not explained in simple terms.

Official Summary Text
The act requires a water right owner that changes the use of their water right in water division 2 from agricultural irrigation purposes to another beneficial use on or after January 1, 2027, to engage in revegetation or a conversion to dryland farming with effective erosion control and weed management on the formerly irrigated agricultural land. The act implements a procedure that includes:
The identification of site-specific criteria and an associated scientific and objective evaluation methodology to measure and determine the success of the revegetation or conversion to dryland farming;
A requirement that the water court appoint a third-party revegetation or dryland farming expert to conduct annual field reviews and issue reports concerning the success of the revegetation or conversion to dryland farming until the revegetation or conversion is successfully established; and
A requirement that the water court:
Order the water right owner to provide financial assurance to the local land use authority to cover the anticipated cost to achieve successful revegetation;
Place limitations on the timing of use or percentage of the water that may be used for the new beneficial use during the revegetation or conversion to dryland farming process; or
If the water right owner has obtained a permit or entered into an intergovernmental agreement that requires financial assurance or establishes requirements governing the timing of use or percentage of the water that may be used for the new beneficial use, incorporate those requirements into the change-of-use decree.
