  "final_investigation_comments": "NCDEQ Division of Water Resources (DWR) Algae Lab reviewed the report. Based on the photos, there is a mix of macroalgae Chara, commonly known as muskgrass, and aquatic plants. From the photos, it looks that the surface mats are composed of dying Chara and attached filamentous green algae attached. Both are not toxin-producing, but dying and decomposing algae may produce bad smells, cause reduction of dissolved oxygen (DO) in water. For more information about filamentous gree algae, please visit: https://www.deq.nc.gov/water-quality/environmental-sciences/fishkill/algae/filamentous-greens/download.\n\nNC Wildlife Resource Commission (WRC) staff investigated the site for fish kill in the pond via kayak and found approx. 200+ total fish mortality of largemouth bass, sunfish and chubsucker. Some fish were still active during investigation around pond. DO readings were taken and were very low all over pond (0.9-1.5 mg/L), and DO Saturation was 10-17%, indicating a hypoxic condition which can be the main reason causing fish kill. (other parameters includes pH 5.5, Temperature 24.6-26.7 degrees C. Conductivity was 98.2-107.2, alkalinity 0.672 dkHCaCO3.)\n\nNCDEQ advises the public to avoid contact with discolored water that could indicate the presence of an algal bloom.  The N.C. Department of Health and Human Services Division of Public Health (DPH) routinely encourages the public to avoid contact with waters with large accumulations of algae and to prevent children and pets from swimming or ingesting water in an algal bloom. Remember: When in doubt, stay out.   \nDPH also reminds the public to take precautions as other microorganisms or pollution may be present in waterbodies that can lead to recreational water illness: https://epi.dph.ncdhhs.gov/cd/water/prevent.html ",
