Through a highly competitive procurement process, INTERA was determined by the St. Johns River Water Management District (SJRWMD) to be the most qualified firm to perform a planning level assessment of the potential impacts of projected 2030 groundwater withdrawals on groundwater levels, stream base flow and Floridan aquifer spring flow rates throughout the eastern portion of the Suwannee River Water Management District (SRWMD) and the northern portion of the SJRWMD. In general, the scope of this project includes making modifications to an existing documented model (the United States Geological Society Mega Model) for the purposes of performing predictive simulations. Work will include modifying the northern portion of the Mega Model to address water resource concerns to both the SRWMD and the SJRWMD.
