AFn, AFn: Total diversion, or storage, authorization for all water rights to be assessed in each water division or group of water divisions, for each of the above categories of use, which are defined as follows:

Municipal and Domestic- The total amount of water authorized for diversion under a water right for this purpose, including non-exempt domestic and livestock uses.

Industrial, Mining, Recreation, or Salt Water Diversions - The total amount of water authorized for consumptive use for each of these categories of use under a water right. In the event there is no specific authorization for consumptive use, the assessment will be based on the total amount of water authorized for diversion under the water right. Diversions that do not conform to the definition for salt water diversion in §304.4 of this title (relating to Definitions) will be assessed at the rate for the category of use(s) authorized by the water right. For any diversion that would fit the salt water diversion definition except for the fact that the watermaster may be required to protect that water right against junior appropriators, the water right holder or agent may achieve conformity with the definition, and be assessed at the salt water rate, by providing to the executive director, at least 60 days in advance of assessment billing, an affidavit waiving such protection. Such an affidavit will be subject to approval by the executive director and must specify the duration for waiving such protection, but must not be for less than one assessment accounting period, and will be coterminous with assessment periods as establish by the commission.

Nonconsumptive Industrial, Mining, or Recreation - under a given water right where part of the authorization for one of these uses is specified as being consumptive, the remainder will be considered nonconsumptive.

Irrigation, Hydroelectric (Priority and Non-priority), Recharge, Spreader Dam Diversions, Stock Raising, Game Preserves, Public Parks or Secondary Use - the total amount of water authorized for diversion for each of these categories of use under a water right.

On-channel Storage - the total conservation storage authorized for impoundment under a water right. This category includes only on-channel reservoirs authorized under the Texas Water Code, except those reservoirs exempted in accordance with Texas Water Code, §11.142.

Ag-wetland - the total amount of water authorized in a water right for diversion for this use. This term also includes the total amount of water authorized in a water right for the diversion for "wetland" use.

Reuse - the amount of water authorized in a water right for diversion for reuse. This assessment will be in addition to the assessment for the other uses authorized in the water right.

Multi-use - the total amount of water authorized under a water right for more than one use where the amount of water is not allocated to each individual use.

Bed and Banks - the total amount authorized for the transportation of water without the reuse of return flows. This term also includes the total amount authorized for the transportation of privately owned groundwater and groundwater based effluent.

Other - the total amount of water authorized for diversion in a water right for a use not otherwise listed.
