Flows for all other streams must be extrapolated or modeled. Modeling is also necessary to estimate flow regimes under future climate conditions. Forest Service managers can use these models to learn more about their forests.", "summary": "", "title": "greater than 250 (km3) Average Annual Flow/Year", "tags": [], "type": "", "typeKeywords": [], "thumbnail": "", "url": "", "minScale": "NaN", "maxScale": "NaN", "spatialReference": "", "accessInformation": "http://www.horizon-systems.com/NHDPlus/NHDPlusV2_data.php", "licenseInfo": "", "portalUrl": "" }
