MD iMAP: Maryland Stream Health - Stream Wader Sites volunteer collected

Metadata Updated: July 23, 2021

This is a MD iMAP hosted service layer. Find more information at The sample sites are color coded according to the Benthic Index of Biotic Integrity (BIBI) scores. Anything below a BIBI score of 3.0 is red (Poor) - 3.0-3.9 is yellow (Fair) - and 4.0-5.0 is green (Good).Begun as a pilot in 2000 - Maryland Stream Waders is a statewide volunteer stream monitoring program managed by Maryland Department of Natural Resources (DNR) - Monitoring and Nontidal Assessment Division. Stream Waders is the volunteer component of the Maryland Biological Stream Survey (MBSS).Goals of Stream Waders are: to increase the density of sampling sites for use in stream and watershed assessments; to improve stream stewardship ethics and encourage local action to improve watershed management; to educate the local community about the relationship between land use and stream quality; and to provide quality assured information on stream quality to state - local - and federal agencies - environmental organizations - and others.Stream Waders is designed to be seamless with the MBSS and several other stream sampling programs in Maryland. MBSS samples are collected at the watershed level (8-digit Hydrologic Unit Code (HUC); about 70 square miles each) - while Stream Waders volunteers sample at a smaller scale subwatersheds at the 12-digit HUC; about 8 square miles each). Thus - Stream Waders data should help 'fill the gaps' left in watershed areas not sampled by MBSS. Stream Waders sample - for the most part - in the sameoverall watersheds each year where MBSS crews sample.
