Summary

An important source of fresh water on Lopez, San Juan, Orcas, and Shaw Islands in San Juan County off the northwestern coast of Washington is glacial-deposit and bedrock aquifers. Two methods were used to estimate recharge from precipitation to the water tables on the islands. A daily near-surface water-balance method, the Deep Percolation Model (DPM), was used to simulate water budgets for the period October 1, 1996, through September 30, 1998 (water years 1997-98) for six small drainage basins?three on Lopez Island and one each on San Juan, Orcas, and Shaw Islands. The calibrated soil and subsoil parameters from the DPM for each small basin were then used in island-wide applications of the DPM where the direct runoff component (which [...]
