The U.S. Geological Survey (USGS) developed a regression model for estimating mean August baseflow per square mile of drainage area in cooperation with National Oceanic and Atmospheric Administration (NOAA) to help resource managers assess relative amounts of baseflow in streams with Maine Atlantic Salmon habitat (Lombard and others, 2021). The model was applied to each reach of a stream network derived from select National Hydrography Dataset Plus High-Resolution (NHDPlusHR) data in the State of Maine south of 46º 21′55″ N latitude. The spatial coverage developed from the stream network contains model-estimated mean August baseflow per square mile of drainage area as an attribute of each NHDPlusHR reach. Please...

NOTE - This map contains two datasets: "Important Anadromous Fish Habitat, Northeast U.S." and "Atlantic Salmon Rearing Areas, Maine"These dataset are part of a suite of products from the Nature’s Network project (naturesnetwork.org). Nature’s Network is a collaborative effort to identify shared priorities for conservation in the Northeast, considering the value of fish and wildlife species and the natural areas they inhabit. "Important Anadromous Fish Habitat" and “Atlantic Salmon Rearing Areas, Maine” are two input used in developing “Lotic Core Areas, Stratified by Watershed, Northeast U.S.” that is also part of Nature’s Network. Lotic core areas represent intact, well-connected rivers and stream reaches in...
