Why has Crystal River Become Saltier?

By |2021-02-28T10:44:01-05:00February 5th, 2021|Below the Water Line|

Crystal River has become saltier because of saltwater intrusion. As developments pump freshwater out of the aquifer for drinking or irrigation, the saltwater aquifers under the freshwater aquifers begin to seep into the freshwater and contaminate it. Draining the aquifer not only leads to contaminated waters, but it also decreases spring venting and causes devastating sinkholes.

Riverbed Scars

You’ve probably seen those sandy lines along the river floor, running through the eelgrass (see picture above). These scars are caused by boat propellers. Scars can also be formed by using hooked anchors that uproot native eelgrass and leave sandy patches in the riverbed. While many boaters believe scraping the bottom is no problem, it takes time for eelgrass to grow back. Often, Save Crystal River will intervene and patch the scars before they fill with gunk and detritus.

Sawgrasses and Salinity

By |2021-01-08T14:01:24-05:00January 4th, 2021|News|

Species diversity in sawgrass is limited, but it fosters lots of life. Typically, alligators use sawgrass to nest. Sawgrasses not only provide habitat, but they also provide a place of refuge for any animal trying to escape the Florida sun or a pursuing predator. One species I didn’t expect to see were barnacles on my dock posts. Due to the rising salinity levels of Crystal River, the once freshwater part of King’s Bay I live on has become salty enough to support barnacles and other, more dangerous, saltwater species.

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!

Turbidity and Salinity in Water Quality

By |2020-08-11T20:27:51-04:00August 11th, 2020|Below the Water Line, News, Science|

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

By |2020-08-11T20:25:22-04:00July 11th, 2020|Below the Water Line, Science, Uncategorized|

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

By |2020-08-11T20:23:55-04:00June 11th, 2020|Below the Water Line, News, Science|

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.
