Nonpoint Source Watershed Project Workshop:
Working Toward Measurable Success

A workshop for federal, state, and local project managers to share expertise on implementing and evaluating successful nonpoint source (NPS) pollution control watershed projects was held September 13 - 16, 1993, in Gaston County and Charlotte, North Carolina. The workshop was hosted by the North Carolina Cooperative Extension Service of Gaston County, the Gaston County Quality of Natural Resources Commission, the Gaston County Soil and Water Conservation District, and Gaston County in cooperation with the U.S. Environmental Protection Agency, U.S. Department of Agriculture, U.S. Geological Survey, North Carolina Cooperative Extension Service, NCSU Water Quality Group, Oregon State University Water Resource Research Institute, and North Carolina Divisions of Environmental Management and Soil and Water Conservation.

Workshop activities included a presentation on Integrated National Monitoring Strategy by Elizabeth Jester Fellows (Monitoring Branch, Office of Wetlands, Oceans and Watersheds, U.S. Environmental Protection Agency (USEPA)); a plenary session addressing key findings from NPS watershed programs, local initiatives for NPS control programs, and opportunities for collaboration among federal, state, and local programs, and introducing the Section 319 National Monitoring Program; 16 work sessions on specific topics; and a tour of the Long Creek Watershed 319 National Monitoring Program Project located in Gaston County.

Selected highlights of presentations and discussions among 95 participants from 27 states are summarized below.

Overview of the Section 319 National Monitoring Program

The Section 319 National Monitoring Program is mandated by Section 319 of the Clean Water Act as amended in 1987. Program goals are to: 1) document the water quality benefits of nonpoint source (NPS) pollution control programs; 2) improve understanding of the effectiveness of NPS efforts; and 3) develop better NPS projects.

Funding for the program comes from a 5% setaside of annual Section 319 funds allocated to U.S. EPA Regions. The process by which 319 National Monitoring Program projects are selected involves identification of candidate projects by the states in consultation with U.S. EPA Regions, review and recommendation of proposed projects by USEPA Headquarters, and approval and awarding of grants by the Regions. At present, the focus of the program is on stream systems. Although the majority of projects funded to date involve agricultural NPS pollution, projects can address NPS problems from sources such as urban or forested areas. Criteria for selection of 319 National Monitoring Program projects include:

Factors Affecting Successful Detection of Water Quality Change

Guidance on monitoring and reporting requirements for Section 319 National Monitoring Program projects may be found in the USEPA document entitled Watershed Monitoring and Reporting for Section 319 National Monitoring Program Projects dated August 1991 and available from the Nonpoint Source Branch, Office of Wetlands, Oceans, and Watersheds, USEPA, Washington, D.C.

Local Project Cooperation and Team Building

Information and Education and Producer Participation

Pre-project Planning: Setting Realistic, Attainable, Measurable Water Quality & Land Treatment Goals

As part of the process of establishing realistic and measurable goals, project teams should write a problem statement that: 1) states what the impaired water use is; 2) identifies the location of the problem; 3) refers to a specific pollutant or pollutants; and 4) identifies a source or suspected source of the pollutant. Once the problem statement has been written, water quality monitoring and land treatment goals can be set. These should be as specific as possible and there must be a mechanism for determining whether or not they have been achieved (they must be measurable).

Examples of effective and ineffective goals are:

Measures of success for each goal must be established at the beginning of the project. Useful measures include sampling to determine concentrations (or loads) of a specific pollutant for goals calling for a specified reduction in a pollutant. Measures such as opinion polls or measuring volume or weight of trash removed from a stream can be used to evaluate progress in efforts to educate watershed residents about conservation.

Land Treatment Implementation Strategy - How Much and Proper BMP Selection

Many questions were raised about this topic and few answers are available. Modeling was suggested as a way to estimate how much land treatment is needed to achieve desired water quality changes; however,the limitations of modeling were noted. Questions for the future include:

Proper Experimental Design for Relating Water Quality Changes to Land Treatment Implementation

Effectiveness of several experimental designs for projects whose objective is to document water quality changes resulting from implementation of land treatment (BMPs and BMP systems) were discussed:

Tracking Land Treatment and Land Use Measurement (s) for Specific BMP Systems

The complexity of the task of tracking treatment and effectively linking t with water quality data was apparent in the lively discussion on this topic. Both the importance of choosing discretely-measurable variables associated with the land treatment itself and an interest in creating measures that rate treatment strength by integrating treatment characteristics (for example, distance of a particular treatment from a water body and coverage in terms of area) were noted.

Monitoring for the Effectiveness of Individual BMPs vs. a System of BMPs

The consensus of workshop participants was that, assuming that the project objective is not specifically to understand the effect of a single BMP, systems of BMPs are more effective in addressing most water quality problems than any individual BMP. For example, to reduce sedimentation of an estuary adjacent to rangeland characterized by overgrazing, the following BMPs might be used simultaneously: restricting livestock access to streams, restoration of riparian areas, rotational grazing, water source management, sediment traps, and gully stabilization. No one BMP is likely to be as effective as some combination of BMPs hosen based upon local conditions and acceptability to farm operators.

Water Quality and Land Treatment Data Storage, Reporting, and Evaluation

The 319 National Monitoring Program projects are required to prepare annual and five-year reports for USEPA using the NPSMS (NonPoint Source Management System) software. Questions about use of the software itself should be directed to Horizon Systems (Cindy McKay, 703-471-0480), on contract to USEPA to provide technical assistance to the projects on software use.

Questions related to the kind of information that should be included or where it should be placed in annual reports (due September first each year) should be referred to Steve Dressing, USEPA (202) 260-7110.

Technical assistance on water quality and land treatment monitoring design and data analysis for 319 National Monitoring Program projects is being provided by both the NCSU Water Quality group (Jean Spooner: 919-515-3723) (for projects located in USEPA Regions I - VII) and Oregon State University Water Resources Research Institute (JoBeth Mullens: 503-737-4026) (for projects located in USEPA Regions VIII, IX, X).

Questions about STORET and BIOS data management systems should be addressed to the following USEPA staff: Lee Manning (703-235-5627), Joyce Boyd (703-235-5586), Dan Parker (703-235-5584) or Clarence Tutwiler (STORET questions only) (703-235-5585).


PROJECT SPOTLIGHT


Monitoring of both land treatment and water quality is necessary to document the effectiveness of nonpoint source pollution controls in restoring water quality. The Section 319 National Monitoring Program, administered by the U.S. Environmental Protection Agency, is designed to support watershed projects throughout the country that meet a minimum set of project planning, implementation, monitoring, and evaluation requirements. The requirements are designed to lead to successful documentation of project effectiveness with respect to water quality protection or improvement. The National Monitoring Program projects comprise a small subset of nonpoint source control projects funded under Section 319 of the Clean Water Act Amendments of 1987. The following article continues a series describing these projects.

Sycamore Creek Watershed, Michigan,
319 National Monitoring Program Project

Project Synopsis

The Sycamore Creek 319 National Monitoring Program project is located in southcentral Michigan (Ingham County). The creek has a drainage area of 67,740 acres that includes the towns of Holt and Mason and part of the city of Lansing. Agricultural lands comprise 52% of the watershed area. Major commodities produced in this primarily agricultural county are corn, wheat, soybeans, and livestock. Other primary land uses are forestry, residen-tial, and business.

Pollutants of concern in Sycamore Creek are sediment, phosphorus, nitrogen, and agricultural pesticides. Sediment deposits are adversely affecting fish and macroinvertebrate habitat and depleting oxygen in the water column. Sycamore Creek has been selected for monitoring, not because of any unique characteris-tics, but rather because it is representative of creeks throughout lower Michigan.

Water quality monitoring will occur in three subwatersheds: Haines Drain, Willow Creek, and Marshall Drain. The Haines Drain subwatershed, where BMPs have already been installed, will serve as the control and is outside the Sycamore Creek watershed. Stormflow and baseflow water quality samples will be taken from each watershed from March through July. Water will be sampled for tur-bidity, total suspended solids, chemical oxygen demand, nitrogen, and phosphorus.

Land treatment will consist primarily of sediment- and nutrient-reducing best management practices (BMPs) on cropland, pastureland, and hayland. BMPs will be funded as part of the U.S. Department of Agriculture (USDA) Sycamore Creek Hydrologic Unit Area (HUA) project.


Project Time Frame

1990 - 1996 (potentially longer if funding is renewed)

Pre-Project Water Quality

The primary pollutant of Sycamore Creek is sediment. Wide-spread aquatic habitat destruction from sedimentation has been documented. Nutrients (nitrogen and phosphorus) are secondary pollutants. Limited contamination of shallow aquifers by nitrate has been detected, but pesticides were not found. Low levels of dissolved oxygen in the creek are a result of excess plant growth and organic matter associated with the sediment.

A biological investigation of Sycamore Creek, conducted in 1989, revealed an impaired fish and macroinvertebrate community. Fish and macroinvertebrate numbers were low, suggesting lack of available habitat.

Channelization of Sycamore Creek is causing unstable flow discharge and significant bank-slumping and erosion at sites that have been dredged.

Nonpoint Source Control Strategy

The Sycamore Creek National Monitoring Program project is nested within a USDA HUA project. The nonpoint source control strategy includes: 1) identification and prioritization of significant nonpoint sources of water quality contamination in the watershed and 2) promotion of the adoption of BMPs that significantly reduce the effects of agriculture on surface water and ground water quality.

Selection of the BMPs will depend on land use. BMPs for cropland will include conservation tillage, conservation cropping sequence, crop residue use, pest management, nutrient management, waste utilization, critical area planting, and erosion control structures. Hayland BMPs will consist of conserva-tion cropping sequence, conservation tillage, pest management, nutrient man-agement, pasture/hayland management, and pasture/hayland planting. BMPs to be utilized on pastureland are conservation cropping sequence, conservation tillage, pasture/hayland management, pasture/hayland planting, fencing, waste utilization, filter strips, and critical area planting.

Critical areas for targeting BMPs are agricultural fields (cropland, hayland, or pasture) within one-half mile of a stream. Major BMPs already implemented in the control watershed are pasture and hayland planting, pasture and hayland management, cover and green manure crops, critical area plantings, conservation tillage, grade stabilization structures, and integrat-ed crop management.

Practice installation and the effect on water quality will be tracked using the database ADSWQ (Automatic Data System for Water Quality). Crop and residue cover will be recorded on a 10-acre cell basis in each subwa-tershed. EPIC (Erosion Productivity Index Calculator) will be interfaced with a geographic information system, GRASS (Geographic Resources Analysis Support System), to estimate changes in edge-of-field delivery of sediment, nutrients, and pesticides and bottom-of-root-zone delivery of nutrients and pesticides resulting from BMP implementation.

Water Quality Monitoring Design

A paired watershed design will be used to document water quality changes in Sycamore Creek. Two subwatersheds within the project, Willow Creek and Marshall Drain, will be compared to the control subwatershed (Haines Drain). BMPs were installed in Haines Drain prior to the commencement of water quality monitoring in 1990. The Willow Creek and Marshall Drain subwatersheds were selected because they had demonstrated excessive sediment loads and they had the largest percentage of erodible land within one-quarter mile of a channel of any other subwa-tershed in the Sycamore Creek watershed.

Twenty evenly-spaced weekly grab samples will be taken for trend detection. The water quality variables measured will be total suspended solids, turbidity, total phosphorus, Kjeldahl nitro-gen, nitrite and nitrate, and chemical oxygen demand. Additionally, storm sampling will be conducted from after snow melt until the appearance of a crop canopy sometime in July. Samples will be collected every one to two hours. For each location and storm, six to twelve samples will be selected for analysis. Automatic stormwater samplers equipped with liquid level actuators will be used.

Additional data collection will include a continuous record of river stage which will be converted to a continuous flow record using a stage discharge relationship and one recording rain gage (installed in each agricultural subwatershed).

Project Water Quality Objectives

The water quality objective is to reduce the impact of agricultural nonpoint source pollutants on the surface and ground water in Syca-more Creek.

Information, Education, and Publicity

The Ingham County Extension Service is responsible for all information and education (I&E) activities within the watershed. These I&E activities have been developed and are being implemented as part of the Syca-more Creek HUA project. Activities include public awareness campaigns, con-servation tours, media events such as news releases and radio shows, display set-ups, workshops, short courses, farmer targeted newsletters, homeowner-targeted newsletters, meetings, and presentations.

Water Quality Data Management and Analysis

Data will be stored in the STORET system and in the USEPA Nonpoint Source Management System.
