One evening we took a field trip to witness methane emissions at a local pond. Getting pond sediment to release methane was simple; we just poked the mucky bottom with a stick. The bubbles that rose to the surface were methane. To “see” the gas we held lit candles over the water surface with garden rakes. Once ignited, methane’s distinctive blue flame briefly danced on the pond’s surface around the candle. If you try this yourself, be careful! https://images.squarespace-cdn.com/content/v1/65368bda2c38623ad62dd9c9/6bdb181f-74a2-44ee-ae84-5f15f22012ad/bluntreservoir.jpg The Water Line - Methane, Roy Blunt Reservoir, Reservoirs vs Lakes - Make it stand out Proposed location of Roy Blunt Reservoir and its watershed. https://images.squarespace-cdn.com/content/v1/65368bda2c38623ad62dd9c9/a4149847-f5f6-4a12-8c0f-9b2a85d2c11c/lake_vs_reservoir.jpg The Water Line - Methane, Roy Blunt Reservoir, Reservoirs vs Lakes - Make it stand out A visual comparison of natural lakes near Hackensack, MN and Lake of the Ozarks, a Missouri reservoir.

Aerobic biological processes incorporate carbon into living organisms where it is either stored or respired (as CO2).

Reservoirs that pull water from the hypolimnion release methane as well as particulate and dissolved carbon. https://www.lmvp.org/news/red-algae monthly 0.5 2023-12-01 https://images.squarespace-cdn.com/content/v1/65368bda2c38623ad62dd9c9/7bf31f1e-fe8c-40e8-9fd3-d46baeb66720/prubescensLakeSurface.jpg The Water Line - Red Algae - Make it stand out Planktothrix rubescens bloom in a Missouri lake. https://images.squarespace-cdn.com/content/v1/65368bda2c38623ad62dd9c9/3e8c17ee-4612-4312-8e93-5343ac298160/rubescensgraph.gif The Water Line - Red Algae - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/65368bda2c38623ad62dd9c9/d80409cc-6cb6-4e50-b4a4-c5111ecaa62e/rubescensflowers.jpg The Water Line - Red Algae - Make it stand out P. rubescens can create red "flower" patterns by seeping through fissures in ice-covered lakes. https://www.lmvp.org/news/wet-weather-and-water-quality monthly 0.5 2023-12-01 https://images.squarespace-cdn.com/content/v1/65368bda2c38623ad62dd9c9/b807cd32-1d21-41bc-bf85-184908032cba/trgatesopen.jpg The Water Line - Wet Weather and Water Quality - Make it stand out Table Rock Lake dam in 2008 with all flood gates open.
