Water's Journey Everglades Notes

The Florida Everglades: A Unique Ecosystem

  • The Florida Everglades is a unique region with beauty and diversity, referred to as Florida's original magic kingdom.
  • Marjorie Stoneman Douglas championed the Everglades, recognizing its uniqueness.
  • Past actions in the Everglades were intended to benefit mankind, but may have gone too far.
  • Draining and development have pushed the Everglades to the brink of collapse.
  • A massive ecological restoration project, the largest ever conceived, has been initiated to protect the Everglades.
    • The project is scheduled to take 40 years and cost over 10,000,000,00010,000,000,000.
    • Success would balance the needs of the Everglades and millions of people.
    • Failure could threaten the survival of South Florida.

Hurricane Wilma and Flood Control

  • Hurricane Wilma, one of the strongest Atlantic hurricanes, prompted mandatory evacuations.
  • A special ops team was stationed in South Florida's water control center to prevent urban flooding.
  • Catastrophic failure of dikes and water control structures is a major danger.
  • South Florida is vulnerable to major flood events, similar to New Orleans.
  • Lake Okeechobee's water level is maintained by remote-controlled dams, gates, and pumps.
  • Breaching of these structures could have catastrophic results, devastating parts of South Florida.

Historical Flooding and the Hoover Dike

  • In the 1920s, killer storms caused massive flooding in Southern Florida.
  • In 1928, a category five hurricane breached a five-foot earthen dike on Lake Okeechobee.
    • Approximately three thousand people died.
  • President Herbert Hoover promised to build a 40-foot dike, leading to the first major flood control effort in South Florida.
    • The dike stands almost 40 feet high and runs for almost 80 miles.

War on Water and the Everglades' Formation

  • Florida legislators declared a war on water, aiming to harness and contain it.
  • Water was declared a common enemy of the state.
  • The Everglades formed after the last ice age, around 5,000 years ago, when sea levels stabilized.
  • Mangrove coastlines, hardwood forests, and cypress swamps developed.
  • An enormous sheet of clear water covered the lower half of the state, flowing south.

Transformation of the Everglades

  • Industrialized settlers transformed the Everglades, seeking farmland, timber, and land for development.
  • Drainage canals were created, exposing millions of acres of flooded land.
  • Killer hurricanes spurred demand for flood protection.
  • A dependable water supply was needed for the growing coastal population.
  • In less than 50 years, over half of the original Everglades was permanently lost.

Exploring the Everglades Watershed

  • A team of explorers and scientists are studying the Everglades watershed.
    • Joe Hynerth and Wes Giles are environmental filmmakers.
    • Scientists Mark Clark and Tom Morris have over 50 years of combined experience in the watershed.
  • Two teams will explore the Everglades ecosystem using different approaches.
    • Jill and Tom will paddle, dive, swim, and hike to cover over 300 miles.
    • Mark and West will conduct aerial observations of the restoration effort.
  • The Everglades watershed extends up to Orlando.
  • Restoration requires managing the quantity, quality, distribution, and timing of water throughout the system.

Headwaters of the Everglades: The Kissimmee Basin

  • The Kissimmee Basin is the source water for the Everglades.
  • The area is located not far from Orlando's theme parks.
  • Lake Russell in the headwaters appears pristine.
  • Dwarf cypress trees are centuries old and indicate past lake conditions.
  • Most big cypress trees were cut down for timber about 100 years ago.
  • Alligators are apex predators in this area, with humans as their only real enemy when they reach a certain size.

Drainage Efforts: Hamilton Distant and the Army Corps of Engineers

  • In the late 1800s, developers sought to drain the Everglades for its potential.
  • Hamilton Distant planned to reroute the Kissimmee River to send water directly to Lake Okeechobee, east and west to the ocean, and stop the flow of water into South Florida.
  • This is now considered one of the biggest environmental mistakes ever made.
  • The Army Corps of Engineers, post-World War II, executed Distant's plan on a massive scale.
  • The Kissimmee River was replaced with a 56-mile long, 30-foot deep channel.
  • Massive ditches were cut east and west out of Lake Okeechobee to the coasts.
  • Over half a million acres of land were drained for farming and development.

Consequences of Channelization

  • Storm water from farms and communities poured into the Kissimmee Canal.
  • The natural cleansing process of the flood plain was disrupted.
  • Nutrient-rich water flowed directly into Lake Okeechobee and then to the Atlantic and Gulf.
  • The canal was completed in 1971, and it was commonly agreed it should never have been built.

Modern Farming and Land Management

  • Farmers like the Williamsons are trying to preserve their land and leading protection efforts.
  • They are converting land into natural wetlands to manage runoff.
  • Others are making land available for water storage.
  • Okeechobee County has five times as many cattle as human residents.
  • More than 5,000,0005,000,000 acres of agricultural land have been converted to suburban sprawl since the 1970s.
  • Open spaces are critical for habitat, water supply, and food source.

Restoration of the Kissimmee River

  • The original Kissimmee River meandered over 100 miles.
  • The river swelled into a flood plain almost two miles wide during rain.
  • This cycle was critical to the ecosystem.
  • Scientists and engineers are backfilling parts of the Kissimmee Canal to restore the river's natural flow path and floodplain.
  • This allows the river to cleanse itself and enhances habitat.
  • The dissolved phosphorus is reduced, and water quality is improved.

Lake Okeechobee and Phosphorus Problems

  • Lake Okeechobee is the fourth largest lake in America.
  • It is the source of major problems for Everglades restoration.
  • Runoff from farms and development has impacted the lake.
  • Phosphorus in the water is devastating coastal estuaries.
  • The restoration plan aims to move more water south and use natural processes to clean it.

Phosphorus and Algae Blooms

  • Phosphorus is introduced into the environment from fertilizers.
  • High levels of phosphorus in water bodies fuel algae blooms.
  • Algae blooms deplete oxygen and block sunlight, causing dead zones.
  • Best Management Practices (BMPs) involve private farmers and local and state governments working together to protect the environment.

Livestock Waste Management and Recycling

  • Confined areas allow for total waste containment.
  • Farmers are turning pollution into products they can sell.
  • Solids are collected and separated, and liquids are reused for wash down or irrigation.
  • Solids are transformed into organic fertilizer.

Storm Water and Its Impact

  • All water on Earth is connected.
  • Storm water runoff picks up contaminants and carries them downstream.
  • A major challenge is to minimize storm water impact.
  • Pollutants gather on the bottom of Lake Okeechobee.
  • Hurricanes resuspend contaminated sediments.
  • Contaminated water is released to coastal estuaries.

Everglades Agricultural Area

  • South of Lake Okeechobee is rich farmland.
  • The area was transformed into agricultural lands with the construction of the Hoover Dike and drainage canals.
  • The area has a rich deposit of peat soil, known as black gold.
  • Protecting this muck soil is critical to the farmers survival.

Soil Subsidence and Challenges for Farmers

  • After drainage, peat soil can burn or blow away.
  • Biomechanical oxidation breaks down carbon in the soil, releasing carbon dioxide into the environment.
  • Rising costs, regulations, and extreme weather events have forced many farmers out of business.

Big Sugar and Public Decisions

  • Big sugar is a powerful political force in Florida.
  • Government subsidies allowed sugarcane farming to thrive.
  • Corporate farming became influential but was also blamed for the failing health of the Everglades.
  • The demand for land, flood control, and the belief in man's destiny drove the ecosystem's decline.
  • It was a public decision to create the Everglades agricultural area through drainage.

Everglades Restoration Fundamentals

  • Cleaning up phosphorus-laden water is essential.
  • Returning sheet flow to the lower basin is important.
  • Creating massive water storage systems is needed to ensure water meets the needs of people, farming, and the environment.
  • The Everglades Forever Act placed a threshold on phosphorus levels not to exceed 10 parts per billion.
  • Private and state partnerships are key to implementing new farming techniques and BMPs.
  • Farmers laser-level fields, conserve water, and reduce direct application of fertilizers.

Progress by Farmers and Challenges

  • Farmers in the Everglades agricultural area have reduced phosphorus discharge by 55%.
  • The goal to drop phosphorus levels to below 10 parts per billion remains costly and elusive.
  • Farmers are faced with the question of whether to preserve the American food supply or sell their land to real estate developers.
  • Urban landscapes have the potential to pollute on a much larger scale.

Impact on Seminole and Miccosukee Tribes

  • The decline of the Everglades has impacted the Seminole and Miccosukee tribes.
  • Both tribes believe that land cannot be owned.
  • They remain true guardians of the Everglades and a powerful voice for their homeland.
  • They are fighting to protect the Everglades the way it was and seeking control over the water.

Wetland Scientists and Phosphorus Impact

  • Wetland scientists study plants, animals, and nutrients, focusing on how phosphorus impacts the ecosystem.
  • Water conservation areas retain overflows of storm water.
  • Cattails thrive on phosphorus-rich runoff and have become a nuisance species.
  • Phosphorus helps plants grow, but it can cause communities to shift and reduce wildlife value.

Phosphorus Levels and Calcareous Paraphyton

  • Scientists have shown how phosphorus changes along a gradient.
  • This information is used to model storm water treatment areas.
  • As the team moves southward, soil samples indicate that phosphorus levels are dropping.
  • Calcareous paraphyton, a community of algae, fungus, and bacteria, indicates clean water.
  • It captures sunlight, grows food for animals, and creates oxygen.
  • If paraphyton is lost due to too many nutrients, it will result in the loss of a key food source.

Constructed Wetlands and Storm Water Treatment Areas

  • Constructed wetlands or storm water treatment areas use plants to remove contaminants from water.
  • A specially engineered mix of plants is used to cope with storm water challenges.
  • STAs use a massive stage process that matches plant species to specific nutrient levels in the water.
  • Nutrient-rich water passes through emergent vegetation, submerged aquatics, and periphyton.
  • These plants cleanse the water and reduce phosphorus levels by about 80%.
  • Clean water then enters the natural wetlands of the Everglades.
  • Storm water treatment areas and best management practices have prevented $2,200$ metric tons of Phosphorus from entering into the everglades.

Conclusion: Commitment and Progress

  • Commitment from environmental organizations, state, and tribal leaders is clear.
  • Federal aid and widespread citizen support are crucial.
  • The Everglades restoration effort is well on its way.
  • In the Kissimmee River, over one-third of the river has been restored.
  • Farmers continue to minimize runoff. By implementing an accelerated schedule to solve these issues, legislator are making good progress with the project.
  • Pioneering scientists are successfully treating billions of gallons of water using aquatic plants.
  • The Everglades is a unique ecosystem and is being restored well.
