Why are Springs Blue?

Next time you’re out at Three Sisters or any other spring, think about how the water you’re swimming through, or paddling on, is rainwater, filtered and cooled through rock, colored by minerals, and reflecting dissolved earth crystals and the blue sky. You’re not only swimming through the water we drink and wash our hands with, but also one of nature’s miracles. No wonder the manatees love it!

Why has Crystal River Become Saltier?

The salinity levels of Crystal River have been rising the past few years largely due to two main factors: acid rain and fertilizer runoff. Acid rain dissolves harmful salts found in concrete, which raise the salinity of freshwater sources, and fertilizer contains many salts which, when over used, can be washed by rain into nearby waterways.

Turbidity and Salinity in Water Quality

While Save Crystal River’s efforts to plant eelgrass does not reduce salinity, the grasses themselves have the capacity to thrive in both saltwater and freshwater. Along with this survival ability, eelgrass helps hold sediment at the bottom of the river floor, which reduces overall turbidity of the water. These traits make eelgrass perfect for restoring Crystal River’s clarity and providing a stable environment for indigenous wildlife. 

Temperature and Dissolved Oxygen in Water Quality

Temperature and dissolved oxygen are just two of the many factors scientists study when determining water quality. Temperature measures how hot or cold the water is, and dissolved oxygen measures the percentage of oxygen dissolved in a given volume of water. Scientists use both of these as an indicator of contaminants or abnormal activity in a body of water.

Introduction to Water Quality in Crystal River

Crystal River Florida is known for its vibrant, azure springs and “Old Florida” landscape.  How can you look out on a sawgrass prairie and not say “wow”?  Even though the landscape remains picturesque, the water quality of the river still drastically declines. Only 40 years ago, one could clearly see fish and manatee swimming below. Now in the main river, it is hard to spot any fish unless they jump from the murky water.  

Where the Eelgrass Grows

It's no secret that the eelgrass in King's Bay is plentiful and abundant. Once planted, the baby grass is kept in a Grow SAV Exclusionary Device  for about a year. This insures the roots are established and those eelgrass plants are ready to take on the aquatic world! But what happens before all of that? Where do those baby plants come from?
