The wadeable 3rd-4th order stream flows over a 12.8 km2 (3160 acre) watershed into the Quabbin Reservoir. The site\u0027s dominant land cover is evergreen and mixed forest. HOPB is located in the Northeast Domain (D01), which encompasses the New England and northern Eastern Seaboard states along with the northern end of the Appalachian range. D01 includes one other terrestrial site and one aquatic site. HOPB is located near the Harvard Forest (HARV) terrestrial site.","citation":null,"relatedIdentifiers":null,"status":{"label":"Operational","uri":"http:\/\/vocabs.lter-europe.net\/elter_cl\/10772"},"yearEstablished":2016,"yearClosed":null,"relatedSites":[{"typeOfRelationship":{"label":"groups with","uri":"null"},"listOfSites":[{"type":"site","title":"Harvard Forest \u0026 Quabbin Watershed NEON - United States of America","id":{"prefix":"https:\/\/deims.org\/","suffix":"9dbbd9ea-21dc-43e3-b55d-42623427e642"},"changed":"2025-09-17T14:42:45+0200"}]}],"siteName":"Lower Hop Brook NEON","shortName":"HOPB","siteType":"Stationary land-based site","protectionLevel":null,"landUse":null,"images":[{"url":"https:\/\/deims.org\/sites\/default\/files\/2020-05\/48754979897_8d68289265_k.jpg","alt":"HOPB Fish Sampling"},{"url":"https:\/\/deims.org\/sites\/default\/files\/2020-05\/49014129957_11bd1bc4b5_h.jpg","alt":"HOPB electrofishing"}]},"environmentalCharacteristics":{"airTemperature":{"yearlyAverage":7.9,"monthlyAverage":null,"unit":"\u00b0C","referencePeriod":null},"precipitation":{"yearlyAverage":1368,"monthlyAverage":null,"unit":"mm","referencePeriod":null},"biogeographicalRegion":null,"biome":"freshwater_rivers","ecosystemType":[{"label":"Fresh Water Rivers","uri":null}],"eunisHabitat":null,"landforms":null,"geoBonBiome":["Fresh water rivers","Terrestrial"],"geology":"The Quabbin Reservoir is generally characterized by metamorphic rocks with intrusion of schist and gneiss.

The clear-water stream has a moderate grade with increasing grading towards the outlet. Minimal beaver activity (dams, ponds) occurs in upper portions of the reach. Large debris dams characterize the reach downstream. This area tends to have high spring flows due to spring snowmelt and lower flows during the summer and fall. The Hop Brook accounts for approximately 2% of annual flow into the Quabbin Reservoir.","soils":"Lower Hop Brook substrate is primarily composed of sand\/gravel, cobbles, and boulders.","vegetation":"Stream riparian vegetation consists primarily of mixed deciduous hardwood forest with primarily beech, oak, maple trees, and interspersed pines towards the outlet.
