Did you know that September 18th is World Water Monitoring Day?
Since 1995 Montgomery County has maintained a stream monitoring program. As a result, the program has tracked water quality and stream condition changes throughout the County.
Monitoring fulfills requirements under state and local regulations and occurs on a yearly basis. DEP monitoring includes collection of:
Data collected is crucial for targeting stormwater management, stream restoration, and guiding the County on long term changes in our environment (including climate change, development, restoration success). In addition, the data is essential to a highly innovative mapping approach. Mapping helps DEP identifying distressed watersheds to help with guiding the County in stormwater management and stream restoration.
Each year over 100 sites per region are monitored. Monitoring occurs throughout the County on a 5-year rotation. Below you can see the last 5-years monitoring rotation schedule by area.
As a result of yearly monitoring, data is generated that helps us understand the overall health of Montgomery County’s Streams. Visit our website to find out your local watershed health.
In 2019 our team spent over 200 days in the field collecting more than 220 distinct samples including:
The fish and benthic macroinvertebrates collected provide us information on water quality and watershed health. These data are then combined into an index used to monitor trends.
