Western Lake Erie Basin Streamflow and Water-Quality Monitoring OKI monitoring and findings Donna Runkle and Ed Dobrowolski April 23, 2019 Problem Large inputs of nitrogen and phosphorus can cause algal blooms and can cause taste and odor problems and introduce cyanotoxins into water supplies. Objective Measure streamflow and collect water- quality samples to quantify daily, seasonal, and annual nutrient and sediment loads from tributaries of the Maumee River that flow into Lake Erie. 2 Streamflow and Water-Quality Monitoring Sites in the Western Lake Erie Basin Map label Station ID Station Name 1 04185935 Auglaize River near Kossuth, OH 2 04186500 Auglaize River near Fort Jennings , OH 3 04188100 Ottawa River near Kalida, OH 4 04190000 Blanchard River near Dupont, OH 5 04191058 Little Auglaize River near Melrose, OH 6 41914444 Little Flatrock Creek near Junction, OH 7 04191500 Auglaize River near Defiance, OH 8 04192500 Maumee River near Defiance, OH 9 04185318 Tiffin River near Evansport, OH 10 04183979 Platter Creek near Sherwood, OH 11 04178000 St Joseph River near Newville, IN 12 04183500 Maumee River at Antwerp, OH---Supergage 13 04183105 Maumee River at SR 101 near Woodburn, IN 14 04183000 Maumee River at New Haven, IN 15 04182000 St Marys River near Fort Wayne, IN 16 04181049 St Marys River at Walcot Street at Willshire, OH 3 Project Partners 4 Water-Quality Parameters Analyzed for Projects Parameter Parameter name/description code (National Water Quality Lab (NWQL) Schedule2425 Total Dissolved Nutrients 00671 (DRP, dissolved reactive phosphate) Orthophosphate, water, filtered, milligrams per liter as phosphorus 00665 (TP, total phosphorus) Phosphorus, water, unfiltered, milligrams per liter as phosphorus 00608 Ammonia, water, filtered, milligrams per liter as nitrogen 00625 (TKN, total Kjeldahl nitrogen) Ammonia + organic nitrogen, water, unfiltered, milligrams/liter as N 00631 Nitrate plus nitrite, water, filtered, milligrams per liter as nitrogen Sediment (analyzed by Kentucky Sediment Lab) 80154 Suspended sediment concentration, milligrams per liter 70331 Suspended sediment, sieve diameter, percent smaller than 0.0625 millimeters (2 samples per year) 5 P Cross-section sampling, Equal-Width Increment (EWI) sampling 6 + autosample to compare with EWI 7 Importance of equal-width and depth integrated sampling 8 Calculating and Applying Coefficients Cross Section Sample Coefficient = Cross Section (EWI) Sample Companion Autosample Companion Autosample Concentration =0.90 mg/L Concentration = 1.00 mg/L 0.90 mg/L Coefficient = 1.00 mg/L Coefficient = 0.90 for this discharge for this season 9 What is a Load? Load= Concentration X Streamflow At Maumee River near Defiance, there was a total phosphorus load of 1,960 metric tons from March 1 to July 31, 2015 Which is about 356 elephants (5.5 metric tons per elephant) 10 What is flow-weighted mean concentration?
