The Water WatchDog program is a simple system for reporting water pollution to County investigators as part of your daily routine — whether you are taking a walk, hiking, walking your dog, cycling or going to work.

Use the Submit a Report button below to submit a Water WatchDog report.

After hours/on weekends please also call the Park Police at 301-949-8010. They are the only respondents at those times. Describe the pollution as a pollution emergency. They will investigate.

View reports already made by selecting the Filter by Date button below. Select other criteria for diplaying reports by using the Search box at the top right of the table.
