owf-data-co-ditch-and-reservoir-companies

This repository contains the Open Water Foundation (OWF) dataset for Colorado ditch and reservoir companies (irrigation water supply companies). This is a foundational dataset that provides unique identifiers and other data for ditch and reservoir companies. The identifiers can be used to link other datasets, such as agricultural ditches and municipal water providers. OWF has created and is maintaining this dataset to facilitate work on various data analysis and visualization projects in Colorado.

The following sections provide a summary of the project repository:

Column names are taken from original sources if possible. For clarity and attribution, agency abbreviations may be added to the original column name. Column name length is not restricted, therefore, some data representations such as Esri shapefiles may contain truncated column names. In such cases, alternative formats such as GeoJSON are recommended.

Descriptions of data columns are also provided in the Notes worksheet within the workbook. This worksheet also details how the original data were downloaded and where to find those files.

Identifier Conventions for OWF_ID

The following conventions are used to create OWF_IDs. Note that for the most part, D=Ditch, I=Irrigation/Irrigating, L=Lateral, R=Reservoir, C=Company.

  • CDC = Canal and Ditch Company

  • CRC = Canal and Reservoir Company

  • DA = Ditch Association

  • DC = Ditch Company

  • DLC = Ditch and Lateral Company

  • DMC = Ditch and Manufacturing Company

  • DRC = Ditch and Reservoir Company

  • DWC = Ditch and Water Company

  • IA = Irrigators Association

  • IC = Irrigation/Irrigating Company

  • IDC = Irrigating Ditch Company

  • IMD = Irrigation and Manufacturing Ditch

  • LA = Lateral Association

  • LC = Lateral Company

  • LDA = Lateral Ditch Association

  • LDC = Lateral Ditch Company

  • LDRC = Lateral Ditch and Reservoir Company

  • LIC = Lateral and Irrigation/Irrigating Company

  • LRC = Lateral and Reservoir Company

  • PC = Pipeline Company

  • RA = Reservoir Association

  • RC = Reservoir Company

  • RCC = Reservoir and Canal Company

  • RDC = Reservoir and Ditch Company

  • RFC = Reservoir and Fish Company

  • RIC = Reservoir and Irrigation Company

  • SA = Shareholders Association

  • UA = Users Association

  • WU = Water Users

  • WC = Water Company

  • Ag = Agricultural

  • Ave = Avenue

  • Crk = Creek

  • Mtn = Mountain

  • Rd = Road

  • Res = Reservoir

  • Spgs = Springs

  • Vly = Valley

  • Ft = Fort

Data Flags

For many data columns, a second column of the same name with the word "_Flag" added to the column name is present. These columns are an indication of data status as it relates to missing data. The following conventions are used:

  • G = Value is known/good.
  • g = Value is estimated (but good). The associated cell is also highlighted in yellow.
  • N = Value is not applicable and a blank cell is expected.
  • M = Value is known to be missing in original source and therefore a blank cell indicates that a value cannot be provided.
  • m = Value is estimated to be missing. The associated cell is also highlighted in gray.
  • z = Value is unable to be confirmed. A value is possible but cannot be confirmed one way or the other. The associated cell is also highlighted in orange.
  • x = OWF has not made an attempt to populate the cell at this time. The value is missing because OWF has not attempted to find the value. The associated cell is also highlighted in black.

Note that colors are visible only in xlsx files and not csv files.

Single-character flags may also be followed with a number, as in g1. These flags are specific to certain columns and are detailed above in the descriptions of the data columns.

Other worksheets within the workbook contain the following:

  • ChangeLog worksheet indicates any changes made to the dataset, the date they occurred and who made the changes.

  • Metadata_DitchReservoirCompany worksheet serves as the metadata for data columns in the DitchReservoirCompany worksheet.

Colorado-Ditch-Reservoir-Companies.csv Contents

This file is the DitchReservoirCompany worksheet saved in csv format. To use this file, do not first open in Excel, because IDs that contain leading zeroes will not show those zeroes. Instead, import the file into a blank Excel file by selecting Data/Get External Data/From Text.

Attribution

The data sources for this dataset are listed below.

  • DitchReservoirCompanyName and BusinessEntity_ID are from the Colorado Information Marketplace's Business Entities in Colorado dataset. The BusinessEntity_ID is a State-assigned identification number. OWF filtered the dataset based on the words "ditch", "irrigation" and "reservoir" and exported the results to CSV files. The combined CSV file can be found here. The dataset was also the source of the EntityStartDate, EntityEndDate and Municipality data columns.
  • Over half of the companies have a physical address listed in the dataset, but not latitude/longitude coordinates. To obtain coordinate data, the dataset was opened in Google Sheets. An add-on named Geocode by Awesome Table can take a physical address and convert it to coordinates, as long as the street address, city, state and zip code are provided.
  • The IBCC_Basin column indicates which Interbasin Compact Committee basin the company is located in. To fill this column, OWF first saved the DitchReservoirCompany worksheet in csv format and then opened the file in QGIS to create a point layer of ditch companies. Then a GIS shapefile of the IBCC basins was overlayed onto the point layer. A shapefile of the basins can be found within the Colorado Water Conservation Board (CWCB)'s Data Viewer. The IBCC Basin layer is within the Admin Boundary category. All of the ditch companies within a specific basin were then selected and labeled with the basin name.
  • The Ditch and Reservoir Company Alliance maintains a list of members on its website. The list was directly copied from the website and pasted into an Excel spreadsheet.
  • Website URLs were found by manually searching for company websites.

Data Workflow

This dataset was first created by downloading the "Business Entities in Colorado" dataset from the Colorado Information Marketplace. Data were filtered to only include entities with the words "ditch", "irrigation" and "reservoir" in the entity name. Further filtering was then required to eliminate entities that were landscaping companies "i.e., "X Irrigation and Landscaping Company". Each entity has a State-assigned identification number, which OWF is referring to as BusinessEntity_ID. Other data columns that come from this dataset include EntityStartDate, EntityEndDate and Municipality. OWF created a unique text identifier (OWF_ID) that may be used in the future to link additional datasets. OWF manually cross-referenced DitchReservoirCompanyName with the DARCA-Members.csv dataset.
From here, the general workflow is as follows:

  1. Data flags are created for many of the data columns that indicate data status as described above.
  2. The data are formatted as a table to allow for data filtering.
  3. The dataset is saved in .xlsx format.
  4. The xlsx-formatted file is opened in TSTool and a short command file (Process-xlsx-to-csv.TSTool) converts the dataset into CSV format.
  5. The xlsx-formatted file is opened in TSTool and a short command file converts the dataset into GeoJSON format. This step is optional and applicable for datasets in which a map will be created or if further processing will occur in GIS application such as QGIS.

How to Use the Data

The Colorado Ditch and Reservoir Companies dataset provides a statewide list of ditch and reservoir companies. There are unique identifiers for each company and the dataset allows cross-referencing the identifiers so that other datasets can be joined. For example, the Colorado Municipal Water Providers dataset uses municipal water provider identifiers and can be used to link to this dataset to provide information about water rental programs between ditch companies and water providers.

The Excel and csv files can be used as tabular datasets as is, to create filtered lists or to link to other datasets. Data-processing software such as TSTool can be used to link this dataset to other datasets. Datasets can be used within GIS software to create maps.

The format and contents of the dataset will change over time. It is recommended to save a copy of the dataset.

Disclaimer

OWF has attempted to create a complete statewide dataset of ditch and reservoir companies. However, this dataset is likely incomplete due to limitations in input datasets. OWF will attempt to fill data gaps as the dataset is used for analysis and funding allows for more data review. OWF provides no guarantee as to the accuracy of the data. Use this dataset at your own risk. OWF welcomes feedback to improve the dataset.

License

The license is being determined. All the data are public so there are not really any restrictions on use.
