How healthy is your river, creek, or stream? Check out our River Report Cards to learn all about the most recent water quality trends on your local waterways. 

Report Card Methods

ShoreRivers' Report Cards are the product of tremendous volunteer effort and scientific analysis. Our experienced staff and Chester Tester, Creek Watcher, and Sassafras Sampler Citizen Scientists collect data at nearly 200 sites throughout the Chester, Choptank, Miles-Wye, and Sassafras watersheds. 

Samples are processed via established scientific protocols and grades are calculated using methods developed by the Mid-Atlantic Tributary Assessment Coalition (MTAC).
