type TimePeriod:

dict

param TimePeriod:

[REQUIRED]

The date range for fetching estimated water allocation. The range must include the start date of a year for that year's data to be included in the response.

Start (datetime) -- [REQUIRED]

The start (inclusive) of the time period. ISO-8601 formatted timestamp, for example: YYYY-MM-DDThh:mm:ss.sssZ
End (datetime) -- [REQUIRED]

The end (exclusive) of the time period. ISO-8601 formatted timestamp, for example: YYYY-MM-DDThh:mm:ss.sssZ

type GroupBy:

list

param GroupBy:

The dimensions available for grouping estimated water allocation.

(string) --

Specifies the dimensions available for grouping and filtering environmental impact data.

type FilterBy:

dict

param FilterBy:

The criteria for filtering estimated water allocation. To determine which dimensions are available to be filtered by, you can first call GetEstimatedWaterAllocationDimensionValues

Dimensions (dict) --

Filters environmental impact values by specific dimension values.
- (string) --
  
  Specifies the dimensions available for grouping and filtering environmental impact data.
  - (list) --
    - (string) --

type AllocationTypes:

list

param AllocationTypes:

The allocation types to include in the results. If absent, returns TOTAL_WATER_WITHDRAWALS allocation types.

(string) --

Specifies the types of water allocation calculations available.

type Granularity:

string

param Granularity:

The time granularity for the results. Only YEARLY_CALENDAR time granularity is currently supported for water allocation. Defaults to YEARLY_CALENDAR if absent.

If requesting partial time periods, data will be returned based on the smallest supported granularity. For example, requesting 2025-04-01T00:00:00Z to 2026-04-01T00:00:00Z with YEARLY_CALENDAR will return all the data for 2026 only.

type MaxResults:

integer

param MaxResults:

The maximum number of results to return in a single call. Default is 1000.

type NextToken:

string

param NextToken:

The pagination token specifying which page of results to return in the response. If no token is provided, the default page is the first page.

rtype:

dict

returns:

    - TimePeriod (dict) --
      
      The reporting period for water allocation values.
      - Start (datetime) --
        
        The start (inclusive) of the time period. ISO-8601 formatted timestamp, for example: YYYY-MM-DDThh:mm:ss.sssZ
      - End (datetime) --
        
        The end (exclusive) of the time period. ISO-8601 formatted timestamp, for example: YYYY-MM-DDThh:mm:ss.sssZ
