Lewis Run is a small wadeable stream that drains a 11.9 km2 (2940 acre) watershed. The majority of the stream reach flows past and through land managed by Casey Trees, a nonprofit organization that raises trees for planting in and around the Washington, D.C. area. The surrounding region is characterized by general land use types including successional fields, pastures, woodlands, and small ponds. This site is located within NEON\u0027s Mid-Atlantic Domain (D02), a densely populated region bounded by the Atlantic Ocean on the east and stretching down the Eastern Seaboard from southern New Jersey to northern Georgia. The Mid-Atlantic Domain includes one other aquatic site and two terrestrial sites. LEWI is located near the BLAN terrestrial site.","citation":null,"relatedIdentifiers":null,"status":{"label":"Operational","uri":"http:\/\/vocabs.lter-europe.net\/elter_cl\/10772"},"yearEstablished":2017,"yearClosed":null,"relatedSites":[{"typeOfRelationship":{"label":"groups with","uri":"null"},"listOfSites":[{"type":"site","title":"Blandy Experimental Farm NEON - United States of America","id":{"prefix":"https:\/\/deims.org\/","suffix":"1a5fbe95-b936-4a0e-8cf5-bbed079cb76e"},"changed":"2025-09-19T09:31:47+0200"}]}],"siteName":"Lewis Run NEON","shortName":"LEWI","siteType":"Non-stationary land-based site","protectionLevel":null,"landUse":null,"images":[{"url":"https:\/\/deims.org\/sites\/default\/files\/2020-06\/geomorphology_survey.jpg","alt":"Geomorphology Survey"}]},"environmentalCharacteristics":{"airTemperature":{"yearlyAverage":12.2,"monthlyAverage":null,"unit":"\u00b0C","referencePeriod":null},"precipitation":{"yearlyAverage":976,"monthlyAverage":null,"unit":"mm","referencePeriod":null},"biogeographicalRegion":null,"biome":"freshwater_rivers","ecosystemType":[{"label":"Deciduous Forest","uri":null},{"label":"Forest","uri":null},{"label":"Fresh Water Rivers","uri":null},{"label":"Rivers","uri":null}],"eunisHabitat":null,"landforms":null,"geoBonBiome":["Fresh water rivers","Terrestrial"],"geology":"Lewis Run is located on land that is part of the Elbrook Formation. This formation is characterized by the presence of limestone, dolomite, shale, and siltstone.","hydrology":"Lewis Run is a small 2nd-order wadeable stream. The stream banks at LEWI on average are very steep and actively eroding, resulting in significant portions of the stream channel containing unconsolidated deposits of silt. Unconsolidated silt deposits range in depth from a few centimeters to over half a meter throughout the entire stream reach. The stream\u2019s substrate composition is gravel, soft sands, and silt.","soils":"The substrate of Lewis Run consists of gravel, soft sands, and silt. Probing at the stream during site characterization in January 2016 showed significant portions of the stream channel where very soft, unconsolidated deposits of silt are present. Unconsolidated silt deposits range in depth from a few centimeters to over half a meter throughout the entire stream reach surveyed.","vegetation":"Riparian vegetation at LEWI is comprised of moderately spaced, largely mature oak and poplar trees with moderately dense ground cover of tall grasses and briar bushes. Vegetation is largely dormant during the winter and fall months, with dense vegetation growing near the stream channel in the spring and summer."},"geographic":{"boundaries":null,"coordinates":"POINT (-77.98322 39.09564)","country":["United States of America"],"elevation":{"avg":152,"min":null,"max":null,"unit":"msl"},"size":{"value":1190,"unit":"ha"},"relatedLocations":null},"focusDesignScale":{"experiments":{"design":"mainly experimentation","scale":"catchment scale"},"observations":{"design":"mainly observation","scale":"entire catchment"},"observedProperties":[{"label":"DNA sequence","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/21400"},{"label":"atmospheric parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20937"},{"label":"carbon to nitrogen ratio","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/21933"},{"label":"chemical parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/10333"},{"label":"genetic parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20942"},{"label":"land cover","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22142"},{"label":"landscape parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20943"},{"label":"soil alkalinity","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22038"},{"label":"soil nutrient","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22260"},{"label":"soil parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20944"},{"label":"water parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20945"},{"label":"water quality","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22312"}]},"infrastructure":{"accessibleAllYear":true,"accessType":null,"allPartsAccessible":null,"maintenanceInterval":null,"permanentPowerSupply":false,"operation":{"permanent":false,"notes":null,"siteVisitInterval":null},"notes":null,"collection":null,"data":{"policy":{"url":null,"rights":null,"notes":null}}},"relatedResources":null,"projectRelated":{"lter":{"lterSiteClassification":null}}}}
