Listed below are summaries of projects funded with Section 205(j) grants by the Indiana Department of Environmental Management that are actively working on researching and planning ways to address nonpoint source pollution issues in watersheds across Indiana.
Nutrient Supergage and HABs at New Harmony (Contract #43799)
The U.S. Geological Survey (USGS) will operate and maintain a continuous water-quality monitoring instrumentation. The instrument will provide continuous data on water temperature, specific conductance, dissolved oxygen, pH, turbidity, nitrate, nitrite, and phosphate. The equipment will also estimate load/yields of nitrate and orthophosphate using the measurements from the nitrate sensor and phosphate analyzer. The data will be made publicly available at the NRTWQ site. USGS will develop and publish surrogate models using continuous and discreet water quality data to estimate concentrations and loads of constituents that are not easily measured in real-time. USGS will also deploy a chlorophyll and phycocyanin sensor to collect discrete samples of cyanobacterial genes, cyanotoxins, and phytoplankton community samples. A model for estimating cyanotoxin levels in the Wabash River will be developed as part of this sampling.
Continued Operation of Two Continuous Monitors on the Ohio River (Contract #56382)
The Ohio River Valley Sanitation Commission (ORSANCO) will continue to operate two previously installed continuous monitors along the Indiana portion of the Ohio River. The two monitors will record temperature, pH, conductivity, dissolved oxygen (DO), turbidity, chlorophyll a, and phycocyanin. In addition, grab samples will be collected and analyzed twice per month at both locations (total 48 samples). Analysis will include nitrate-nitrite, Total Kjeldahl Nitrogen, Total Phosphorus, Soluble Reactive Phosphorus (SRP), Total Suspended Solids (TSS), Dissolved Organic Carbon (DOC), chlorophyll a, algal taxonomy, and algal toxins. The Grantee shall calibrate each continuous monitor twice per month (total 48 calibrations). ORSANCO also maintains a website to receive continuous monitoring data. The data will also be analyzed and reported for causes of algal blooms.
Twin Creek-Lick Branch Planning (Contract #56800)
Washington County Soil & Water Conservation District (SWCD) will produce a watershed management plan (WMP) for the Twin Creek-Lick Branch watershed. The SWCD will implement a water monitoring program to gather reliable data to understand and prioritize watershed problems. Baseline data will be analyzed with local land use data to help the steering committee to prioritize locations in the watershed. Washington County will perform an outreach and education program to include a socio-indicator survey, media materials, brochures and flyers, education field days, presentations by staff, a clean-up event, and an educational display for events.
Lower Salt Creek WMP (Contract #47451)
Lawrence County Soil & Water Conservation District will produce a watershed management plan (WMP) for the Lower Salt Creek Watershed, Hydrologic Unit Code (HUC) 0512020808. The watershed plan will include all elements listed in the State’s Watershed Management Plan Checklist (updated 2009). They will develop a steering committee of local stakeholders to guide the development of the WMP. Lawrence County will conduct an education and outreach program designed to educate citizens on problems and solutions associated with nonpoint source pollution in the watershed. Lawrence County’s outreach program will include development and distribution of newsletters, flyers, social media updates, and press releases. They will hold annual workshops or field days along with youth educational programs and stream/roadside clean up events.
Upper White River WMP (Contract #48449)
Delaware County Soil & Water Conservation District (SWCD) will produce a watershed management plan (WMP) for the Upper White River Watershed, Hydrologic Unit Codes (HUC’s) 0512020101, 0512020102, 0512020103. The WMP will include all elements listed in the State’s Watershed Management Plan Checklist (updated 2009). The SWCD will develop a steering committee of local stakeholders to guide the development of the watershed management plan along with an advisory board. Delaware County will partner with Ball State University to engage student in the planning project and will conduct a monitoring program that utilizes existing water quality data and develop new data. They will conduct an education and outreach program designed to educate citizens on problems and solutions associated with nonpoint source pollution in the watershed. Delaware County’s outreach program will include development and distribution of newsletters, stakeholder mailings, and press releases. They will hold quarterly education events.
