Tampa Bay area's recent rainfall surge might help relieve our drought

The C.W. Bill Young Regional Reservoir is now about 72% full thanks to recent rainfall, according to Tampa Bay Water officials.

In addition to rain, river flows have picked up since late August. The reservoir that serves Hillsborough, Pinellas, and Pasco counties is now about 72% full.

After a prolonged drought and a spike in rainfall over the past few weeks, the Tampa Bay area could be on the fast track to recovery.

On March 1, the Southwest Florida Water Management District announced a Modified Phase III “Extreme” Water Shortage due to significant rainfall and river flow deficits, as well as projected low regional reservoir levels.

On Sept. 22, Swiftmud officials extended watering restriction rules through March 31, 2027.

Like most of Florida, the greater Tampa Bay Region has faced a depleted water supply for two consecutive summers, resulting in water shortages and restrictions on lawn watering and other measures.

In addition, local jurisdictions are cracking down on offenders. For example, Tampa has implemented fines up to $500 and a mandatory court appearance for violators.

But our recent rainfall may be improving things.

The C.W. Bill Young Reservoir supplies water to residents in Hillsborough, Pinellas, and Pasco counties.

Warren Hogg, chief science officer with Tampa Bay Water, says the reservoir held about 5.5 billion gallons a month ago.

“River flows have really picked up with rain since late August, and our reservoir is currently up to about 11.2 billion gallons, or about 72% full. So the recent rains and river flows have helped us make a significant improvement in reservoir storage,” said Hogg.

He added even more rain could ease water restrictions.

“(Swiftmud) looks at their hydrologic indicators, water levels in lakes, wetlands, aquifers, and rivers, and they also look at the public supply systems like ours to see what's needed," said Hogg. "They took action in September to extend the water restrictions through the end of March 2027, but if conditions improve, that could be changed."

According to Hogg, year-round water conservation practices shouldn’t be an afterthought.

“It's important that we talk about conservation not just as a response to a drought," he said. "We'd like for people to think about their landscapes and watering. When you have a watering day, you water on your day only if you need to. It's not a requirement. It's just your day that you can water if needed.”

Tampa Bay Water has a long-term plan they update every five years. It contains population and demand growth projections that help them plan for new water supply projects.

They also urge residents to continue conserving water to help combat future droughts.

“Use what you need. Don't use anything that you don't need. It helps protect the environment. It saves you money. It puts us in the best position to meet the demand in the future and have fewer of these emergency-type conditions,” said Hogg.
