WATER DISTRICT

ADDITIONAL STUDIES

Results from the Recharge Basin are encouraging. If the District is to be successful in identifying and implementing solutions to the declining groundwater levels, additional studies will be required. Following is a brief discussion of additional studies being contemplated:

Groundwater and Multiple Resources Integration Planning Study

A Groundwater and Multiple Resources Integration Planning Study, covering the entire District, will be developed. The plan will identify potential sources of water for recharge, concepts for bringing the water to the District and methods for delivery of the water to recharge basins. It will also investigate areas suitable for surface water delivery. The District is currently seeking to fund this study by applying for a grant under the Local Groundwater Management Assistance act of 2000 (AB303) which is a California grant program to assist local agencies in better managing their groundwater resources. This program is administered by the California Department of Water Resources.

Monte Vista Avenue Pilot Recharge Basin-Phase II

Results from operation of the existing Pilot Recharge Basin are very promising. In order to recharge large volumes of water, basins substantially larger than the 0.22 acres of the existing basin will be required. The average daily recharge rate of up to 2.72 vertical feet per day is very good. It is anticipated however, that as larger basins are used the average recharge rate will likely be less. Consultants working for the District have recommended construction and operation of a larger basin (Phase II Project) to evaluate recharge rates on a larger scale operation. They propose a four-acre basin divided into one-acre cells. Operation of the four cells would allow one to be drying while others are recharging.

Turlock Airport Recharge Basin

Lateral movement of groundwater tends to be slow. In order to recharge large volumes of water it will be necessary to use a number of recharge sites dispersed around the District. Plans are underway to construct a pilot recharge basin in the vicinity of the Turlock Airport. Soil borings will be conducted to determine the most suitable location. The Turlock Irrigation District has indicated a willingness to supply water subject to the condition of sufficient water being available.
