RPS Scenario Fact Sheet Series

The RPS Scenario Fact Sheet Series was developed for beginner RPS Tool users who have a basic understanding of RPS concepts but are uncertain about how to begin their own screening. Each fact sheet provides a starting point for a specific screening scenario (e.g., prioritizing watersheds for nutrient management) by briefly describing methods to identify relevant watersheds and highlighting example indicator selections.

Watershed Tools for Local Scale Projects. Although the most common RPS Tools are statewide in coverage, they adapt easily to use on smaller, sub-state areas such as ecoregions, medium-sized river basins and counties. This document guides local users in the basic ways they can use the RPS Tool on their own area of interest while still referring to its statewide data as a broader, comparative context.

Watershed Tools for Tribes. The RPS Tool can support comparative assessment of watersheds that contain tribal lands within any given state. This document provides steps for tribes to follow when identifying and screening a subset of watersheds with tribal lands, or when screening watersheds immediately adjacent to tribal watersheds.

Developing New RPS Indicators. Although hundreds of watershed indicators are publicly available at one watershed scale (HUC12), nearly all RPS projects find needs or opportunities to supplement these with more from their own area’s datasets. This document addresses several crucial elements for developing new RPS indicators that will be fully compatible with the RPS Tool and its existing indicator data.

Restoration and recovery literature database. is a key-worded and partially annotated collection of over 1600 technical publication citations in one downloadable MS Access file. The contents of this database are citations and annotations of papers that show relationships between specific water or watershed characteristics and their effect on restorability. Many of these papers played a substantial role in providing background information for developing RPS indicators. Because of its special coding, you must download this file and use it locally. Note that your copy of this database is open, enabling you to add new references or key words if desired.

Using Expert Elicitation in RPS. As an assessment process that attempts to estimate present conditions but also future environmental responses, RPS is difficult to validate with certainty. Expert elicitation offers a structured approach to applying expert opinion insights on watershed condition and prospects for restorability, as an input to QA/QC of RPS watershed rankings. This document was based on experiences with RPS and expert elicitation in a statewide RPS project with substantial local involvement.

Urban Waters WRAP River System Project Report - Use of RPS for Watershed Analysis and Water Equity Mapping
RPS Screening for Land-Based Sources of Pollution that Stress Coral Reefs. The purpose of this 2021 document is to illustrate how the Recovery Potential Screening Tool can be set up to evaluate and compare watersheds for sediment and nutrient runoff into coral reef ecosystems. This document helps set up the tool, select appropriate indicators for evaluating where conditions promote the likelihood of sediment and nutrient runoff, and interpret the outputs for purposes of prioritizing management activities.
A Method for Comparative Analysis of Recovery Potential in Impaired Waters Restoration Planning. This paper appeared in Environmental Management journal in August 2009. It describes an indicator-based method for setting restoration priorities among large numbers of impaired waters through using recovery potential screening. The paper covers the screening methods, their programmatic purpose, and three state or multi-state scale studies. The original publication available at www.springerlink.com remains relevant as a discussion of general approach and need within watershed programs, but it precedes many of the advances in RPS Tool development and many more recent RPS projects.

RPS of Kentucky Watersheds in Support of Nutrients Management. Between 2013 and 2015, EPA Office of Water assisted several states in performing statewide watershed assessments as input to nutrients management strategies and priority setting. Each RPS nutrients project was designed to help states apply recommendations from the EPA Office of Water 2011 nutrients policy memorandum. The two-stage approach in each state project compared HUC8 watersheds in a first, targeting stage and then focused on screening and comparing HUC12s in a second, implementation-oriented stage. All the RPS nutrients projects encouraged state-specific customizing of the approach in identifying stage 1 scenarios, establishing state approaches for priority watershed identification, and selection and weighting of the most nutrients-relevant indicators for use in both stages. Kentucky’s RPS tool contained 300 indicators with full statewide coverage at one or more of the HUC14, HUC12, or HUC8 scales (the majority – 281 of 300 - are at HUC12 scale). Stage 1 of this analysis examined an urban-suburban scenario for nutrients management and a rural-agricultural scenario statewide. A more detailed Stage 2 screening focused on the HUC12 subwatersheds within single HUC8s from each scenario in this report.

Multi-Scale Screening Assessment of Recovery Potential in Maryland Watersheds. This 2010 screening assessment was undertaken collaboratively by Maryland Department of Environment (MDE) and the EPA to determine which of the impaired watersheds were the strongest candidates for restoration and re-attainment of water quality standards. The purpose was to help inform strategies for targeting restoration efforts where they would be more likely to result in successful restoration progress and eventual removal of currently impaired waters from impaired waters lists.

A Rapid Screening Assessment of Brook Trout Recovery Potential in Mining-Impacted Middle Atlantic Region Watersheds. This 2008-2009 study was a joint RPS effort of state and federal agencies with common interests in rehabilitating abandoned mine lands, restoring native fish habitats and returning impaired waters to healthy condition. Results increased the awareness of mutual restoration interests among fisheries, mining and water quality agencies and programs at state and federal level and led to new funding in some high-ranking watersheds.
