ERF1_2 -- Enhanced River Reach File 2.0


The digital segmented network based on watershed boundaries, ERF1_2, includes enhancements to the 
U.S. Environmental Protection Agency's River Reach File 1 (RF1) (USEPA, 1996; DeWald and others, 1985) 
to support national and regional-scale surface water-quality modeling.  Alexander and others (1999) developed 
ERF1, which assessed the hydrologic integrity of the digital reach traces and calculated the mean water 
time-of-travel in river reaches and reservoirs.  ERF1_2 serves as the foundation for SPARROW (Spatially 
Referenced Regressions (of nutrient transport) on Watershed) modeling.  Within the context of a Geographic 
Information System, SPARROW estimates the proportion of watersheds in the conterminous U.S. with outflow 
concentrations of several nutrients, including total nitrogen and total phosphorus, (Smith, R.A., Schwarz, G.E., 
and Alexander, R.B., 1997).  This version of the network expands on ERF1 (Version 1.2; Alexander, et al., 1999) 
and includes the incremental and total drainage area derived from 1-kilometer (km) elevation data for North America.  
Previous estimates of the water time-of-travel were recomputed for reaches with water-quality monitoring sites that 
included two reaches.  The mean flow and velocity estimates for these split reaches are based on previous estimation 
methods (Alexander et al., 1999) and are unchanged in ERF1_2.  Drainage area calculations provide data used to 
estimate the contribution of a given nutrient to the outflow.  Data estimates depend on the accuracy of node connectivity.  
Reaches split at water-quality or pesticide-monitoring sites indicate the source point for estimating the contribution and 
transport of nutrients and their loads throughout the watersheds.  The ERF1_2 coverage extends the earlier drainage area 
founded on the 1-kilometer data for North America (Verdin, 1996; Verdin and Jenson, 1996).  A 1-kilometer raster grid of 
ERF1_2 projected to Lambert Azimuthal Equal Area, NAD 27 Datum (Snyder, 1987), was merged with the HYDRO1K flow 
direction data set (Verdin and Jenson, 1996) to generate a DEM-based watershed grid, ERF1_2WS_LG.  The watershed 
boundaries are maintained in a raster (grid cell) format as well as a vector (polygon) format for subsequent model analysis.  
Both the coverage, ERF1_2, and the grid, ERF1_2WS_LG, are available at:  URL:https://water.usgs.gov/lookup/getspatial?erf1_2.

Sandy Beach Ecosystems, California South Coast MPA Baseline Study, 2011 to 2013

Sandy beaches are among the most intensely used coastal ecosystems for human recreation and are vitally important to coastal economies. Beaches support unique biodiversity and provide essential ecosystem functions and services including endemic invertebrate communities and food webs that are prey for birds and fish, buffering and absorption of wave energy by stored sand, filtration of large volumes of seawater, extensive detrital processing and nutrient recycling, and the provision of critical habitat and resources for declining and endangered wildlife, such as shorebirds and pinnipeds. Sandy beaches compose 36% of the 693 km of shoreline in the South Coast (SC) region, including the California Channel Islands. The goal of this ecological characterization study is to provide a quantitative, baseline description of sandy beach ecosystems in the region from which future ecological changes may be assessed, and to document any differences that may already exist between sandy beaches located within and outside of Marine Protected Areas (MPAs). We also evaluated potential ecological indicators for monitoring and developed and tested new protocols for potential use by citizen-scientists and educators.

California Spiny Lobster (Panulirus interruptus), California South Coast MPA Baseline Study, 2012 to 2013

The South Coast Lobster Research Group (SCLRG) was formed in 2011 in response to interest in how MPAs may affect the abundance, size, and behavior of the California spiny lobster (Panulirus interruptus). The SCLRG is a partnership between scientists, managers, stakeholders, and volunteers, and encompasses personnel from the San Diego State University (SDSU), Scripps Institution of Oceanography (SIO), the San Diego Oceans Foundation (SDOF), the California Department of Fish and Wildlife (CDFW), and the California Lobster Trap Fishermen’s Association (CLTFA). We identified five sites in the South Coast Region at which to work, each with a newly established MPA: (1) the Cabrillo SMR in San Diego, (2) the South La Jolla SMR in La Jolla, (3) Swami’s SMCA in Encinitas, (4) the Laguna Beach SMR in Laguna Beach, and (5) the Pt. Vicente SMCA in Palos Verdes. Inside and outside of MPAs at each site, we conducted daytime SCUBA-based transect surveys of rocky reefs (5 – 15 m depth) between May and September of 2012 and 2013. The number of lobsters in four different size categories, as well depth, relief, and benthic habitat features (biogenic and non-biogenic) were recorded on each transect.

Rocky Intertidal Ecosystems, California South Coast MPA Baseline Study, 2001 to 2014

The South Coast Study Region (SCSR) encompasses a broad section of southern California including both mainland and island coastal regions.  The exceptionally high diversity of marine life in this region is largely due to the mixing of several major oceanographic current systems, and the region is characterized by strong gradients in environmental conditions. Rocky shores characterize approximately 26.83% of the SCSR, and in many areas attract a large number of individuals who frequent the intertidal zone for recreation, education, and for collecting flora and fauna for food, fish bait, or decoration. Rocky intertidal ecosystems are one of the most heavily human-­‐impacted ecosystems along the mainland southern California coast (in addition to sandy beaches) due to their ease of access, and has made them particularly vulnerable to the negative effects of human activities resulting from both extraction (harvesting and collecting) as well as physicaldisturbance (trampling, overturning and handling).
