Water Supply for Multiple Stakeholders: 

Water Supply for Multiple Stakeholders By John E. Garlanger, Ph.D., P.E. Ardaman andamp; Associates, Inc.

Peace River Basin: 

Arcadia Zolfo Springs Bartow Peace River Basin Charlotte Harbor

Current Land Use in Peace River Basin above Arcadia: 

Current Land Use in Peace River Basin above Arcadia

Background Information: 

Background Information At Charlotte Harbor: Basin Area = 2,350 sq. mi Average Rainfall = 5,850 mgd (1 in/yr = 175 cfs = 110 mgd) Current Water Use = 350 mgd At Arcadia: Basin Area = 1,367 sq.mi. Average Rainfall = 3,370 mgd (1 in/yr = 100 cfs = 64.5 mgd) Current Water Use = 300 mgd

Water Budget: 

Water Budget Inputs Rainfall Discharge from Floridan Aquifer Outputs Streamflow Evapotranspiration Recharge to Floridan Aquifer

Southern Water Use Caution Area: 

Arcadia Southern Water Use Caution Area Bartow Zolfo Springs Charlotte Harbor Tampa Bay Bradenton Sarasota

Groundwater Withdrawals in Southern Water Use Caution Area: 

Total Withdrawal in 2001 = 750 mgd Groundwater Withdrawals in Southern Water Use Caution Area

Change in Net Deep Recharge in Peace River Basin Above Arcadia: 

Change in Net Deep Recharge in Peace River Basin Above Arcadia Net Recharge for Current Period = 4.2 in/yr Net Recharge for Historic Period = 2.7 in/yr Change in Net Deep Recharge = 1.5 in/yr

Change in Evapotranspiration Above Arcadia: 

Change in Evapotranspiration Above Arcadia ET for Current Period* = 38.2 in/yr ET for Historic Period** = 39.2 in/yr Change in Evapotranspiration = -1.0 in/yr * Based on impervious area of 67 sq.mi. ** Based on impervious area of 20 sq.mi.

Cumulative Impact of Groundwater Withdrawals and Urbanization at Arcadia: 

Cumulative Impact of Groundwater Withdrawals and Urbanization at Arcadia DStreamflow = DNet Recharge + DET = +1.5 in/yr – 1.0 in/yr = 0.5 in/yr = 50 cfs (32.2 mgd)

Conclusions: 

Conclusions Additional groundwater users are possible but will be limited. Surface water withdrawals will be necessary to meet future water supply requirements. All Stakeholders will need to work together to develop a sustainable water supply for the Peace River Basin.
