General Information

Oak Ridges Moraine Groundwater Program

Database

Data management is one of the most critical areas where the ORMGP partnership continues to have considerable success. A robust data model has been built to house a wealth of water related and geological information required for hydrological and hydrogeological analysis of watersheds originating on the Oak Ridges Moraine.

A concerning issue related to water data is the large number of practitioners that are out in the field collecting water data. At every level of government there are many different departments, ministries and agencies all collecting water related data – often in the same water bodies, without knowing what others are collecting. These data are stored on individual computers and files, and then used to inform the decisions for which they were collected. However, they eventually become lost and therefore unusable for longer term decision making. Having initially begun with the Ministry of the Environment’s (MOE) Water Well Information System (WWIS) database, the ORMGP’s database has now grown to 70 Gigabytes, and into what is likely the most comprehensive, actively managed water related database in Canada. The data management model goes well beyond traditional approaches in many powerful ways, two important ones being: i) the incorporation of temporal data measurements such as pumping rates, water quality results, and long term water level measurements; and ii) by assigning each well screen to a geological unit/aquifer using an “authoritative” geological interpretation.

An updated 2021 Database manual is now available:

So what is the purpose of collecting and managing all of this water data? 

If it cannot be brought to bear on future decisions, then indeed it might be a waste of time and energy. So with the ORMGP, the path forward is to ensure that the data is: i) of a high quality (we are continually correcting and fixing poor data); ii) readily accessible; and iii) where possible, interpreted in smart, responsible ways so as to inform decision making.

Although the concept of “Data Driven Decision Making” sounds perfectly reasonable, in practice it is not implemented nearly as often as one would think. External influences (e.g. pressure from clients, money, poor access to data, etc.) can often have more of an influence on any given water management decision than turning to the data for answers. Sometimes it can can make sense to have other influences drive decisions – but the reality is it is often the cost of searching out past data that prevents practitioners from incorporating ‘what we know’ (i.e. data) into decision making. By creating a one-window approach to accessing water related data, the ORMGP program aims to allow practitioners and decision makers to at least factor ‘what the data says’ as a key element of any given decision.

Since the inception of the program in 2001 the database has grown and as of late 2019, now incorporates:

The main database is hosted on the program’s server with a synchronization procedure in place to ensure that up-to-date information is routinely shared between the main database, the program’s website and technical staff at partner agencies. Several scripted database routines are scheduled to run every weekend. These routines update key tables in the database that ensure that the program’s website is up-to-date with the database. As a consequence of the established procedures the website will be out of synchronization with the database by a maximum of only one week. Program data has been interpreted in many different ways and interpretations, as well as the raw data, are both made readily accessible via the program’s website. The 2021 ORMGP Database Manual and other relevant guides can be found under Publications and Tutorials.

A significant component of the data management program has been to inventory, digitally scan and photograph key hydrogeological reports and documents. This key “knowledge management’ plank has led to over 11,000 documents now scanned and available to partner agencies and consulting firms as pdf files.

The need by all agencies for ready access to up-to-date, high quality data has been is fundamental to sound water resource management. The program continues to assist partner agencies to address this need by fostering data collection and sound data management.
