Its oligotrophic lake
- Eutrophic
Large amount of nutrients
shallow
lots of alga growth
low oxygen
- Oligotrophic
water with less nutrients
more depth
more clarity
- Freshwater
Water with minimal amounts of solutes and dissolved salts.
- Watershed
an area of land that flows into a specific river, basin, or sea
- Hypoxia
when oxygen in the water is so low it cannot support marine life
- Gulf of Mexico Dead Zone
Hypoxia- oxygen in the water is slow it cannot support marine life.
- Eutrophication
the process of excessive nutrients in the water which cause a dense growth of plant life, suffocating the life below
- Nitrates
. Nitrates are common components of fertilizers and explosives
- Phosphates
phosphate is an inorganic compound composed of a phosphorus atom bonded to four oxygen atoms.
- Erosion
the process where rocks are broken down by natural forces such as wind or water.
- Riparian Buffer Strip
a vegetated “buffer-strip” near a stream, which helps to shade and partially protect the stream from the impact of adjacent urban, industrial or agricultural land use.
- Aquifer
is an underground layer of water-bearing, permeable rock, rock fractures, or unconsolidated materials
