Storm events drive the external loading of sediments and nutrients including nitrogen (N) and phosphorous (P) into reservoirs. Cypress Creek is the main external input into Brewer Lake, a drinking reservoir for more than 90,000 people in central Arkansas. Brewer Lake has reoccurring algal blooms linked to inorganic nutrient availability, leading to nuisance odor and taste issues. To understand the impact of storm events on the external loading of Brewer Lake, we sampled storms by deploying an ISCO-6712 prior to and during storm events at the USGS Gage for Cypress Creek near Birdtown, Arkansas. At least three samples were processed per storm to collect and analyze data for the inorganic nutrients ammonium (NH4), nitrate (NO3) and phosphate (PO4). Storms were ranked by severity via difference between baseflow and peak maximum discharge during sample collection. Temporal patterns of nutrient concentrations were analyzed by quantifying the shift from initial baseline to the most extreme values (above or below baseline), to account for dilution or enrichment during storms. Based on preliminary data, Pearson correlation showed trends between severity and dilution of NO3 (r = -0.760) and between severity and enrichment for NH4 (r = 0.894), with a strong correlation between severity and enrichment for PO4 (r = 0.972, p<0.05). Concentrations of NH4, NO3 and PO4 at the sample nearest to the peak of each storm were analyzed in relation to severity, with positive trends for NH4 (r = 0.939) and NO3 (r = 0.907), with PO4 (r = 0.970, p<0.05) being seen as strongly correlated. The trends and correlations stated indicate that higher storm severity increased the degree of dilution or enrichment of inorganic nutrients, with severity also being linked to nutrient concentration at peak discharge. More analysis of total N and P, turbidity and particulate N and P will provide a greater understanding of external loading from Cypress Creek into Brewer Lake.
