U.S. Geological Survey Water-Supply Paper 2394 studied Lee Valley, a 2.25-square-mile basin in mountainous granitic terrain about 18 miles east of San Diego, drained by Jamul Creek. The aquifer is three zones: weathered regolith, a fractured transition zone, and unweathered bedrock. Reported yields are low, with a median of 15 gallons per minute, and a few wells above 100 gallons per minute. Wells near each other can differ sharply. Recharge is primarily infiltration of precipitation. Groundwater moves toward Jamul Creek.
The County of San Diego 2011 groundwater study, Jamul-Dulzura section, describes Bee Valley and Deerhorn Valley wells in fractured bedrock with water levels from 4 to 174 feet below the top of casing between 1981 and 2008. Wells JAM-08 and JAM-09 rebounded as much as 150 feet in one wet season, from August 1990 to April 1991, and fell as much as 100 feet between February and August 1983. The county reads that swing as low storage and localized, rapid water-table declines, with recovery in very wet years.
California DWR Well Completion Reports compiled in the site well-depth file (generated January 30, 2026). Depth and yield figures below use the domestic water-supply reports tagged with that city. Jamul has 643 domestic reports. Median depth is 500 feet, and the middle half fall between 305 and 700 feet. Median reported yield is 15 gallons per minute, the same median USGS reported for Lee Valley. The county air-lift caveat applies: a short test can outrun the sustainable rate.
Published Jamul jobs already show that spread. One pull brought a 1.5 HP pump up from about 756 feet. Another replaced a pump at an 80-foot setting. A production test ran on a pump set at 481 feet (756-foot pull, 80-foot setting, 481-foot test). The public Recent Work file lists 33 Jamul projects. The six job cards already on this page stay as they are.

What did the Lee Valley study find about Jamul-area wells?
USGS Water-Supply Paper 2394 describes Lee Valley, drained by Jamul Creek, as a fractured granitic aquifer. The median reported yield was 15 gallons per minute, and wells near each other can produce very different amounts. Recharge is mainly from precipitation.
How much do Jamul water levels move?
In the county's 2011 record for Bee Valley and Deerhorn Valley, fractured-bedrock water levels ranged from 4 to 174 feet below the top of casing. Two wells rose about 150 feet in the wet season of 1990-1991 and fell about 100 feet in the dry months of 1983.
Why do Jamul pump settings in our jobs range from 80 feet to 756 feet?
Those are published settings on three different Jamul wells: about 756 feet, 80 feet, and 481 feet. Domestic completion reports tagged Jamul have a median depth of 500 feet, with the middle half between 305 and 700 feet. Fracture-controlled wells are not one depth.
Our drilling fleet includes a Gefco rotary drill rig capable of drilling to 1,000+ feet. We use PVC and steel casing depending on well depth and geology, with gravel pack completion for optimal water production.
Frequently Asked Questions
How deep do wells need to be drilled in your area?
Well depth in your area typically ranges from 150 to 800 feet depending on local geology and groundwater levels. Our team conducts a site assessment to determine the optimal depth before drilling begins.
How long does it take to drill a new well?
Most residential wells take 1-3 days to drill, depending on depth and rock conditions. The complete process including pump installation and plumbing typically takes 3-5 business days.
How much does well drilling cost in your area?
Well drilling in your area typically costs $45-$85 per foot, with most wells totaling $15,000-$45,000 depending on depth, casing requirements, and equipment needed. We provide free estimates before any work begins.
