Post- n r 3 W2 iv 1 4 u 1 e 6 5 0 2 e 0 R o depositional processes which promote jointing, fracturing, and solution activity of k 2 l C d e exposed bedrock generally increase the hydraulic conductivity (permeability) of a E o County Road 1100 N R the upper portion of bedrock aquifer systems. Because permeability in many ty n u places is greatest near the bedrock surface, bedrock units within the upper 100 o C Laketon Bog feet are commonly the most productive aquifers. 7 8 Nature Preserve 12 10 11 Laketon 8 9 8 11 12 7 Bedrock aquifer systems in the county are overlain by unconsolidated deposits of 11 12 7 9 10 varying thickness. In places, along the Wabash, Salamonie, and Mississinewa C Rivers, bedrock is exposed or lies within 10 feet of the surface. However, the o Ijamsvilleu County Road 1000 N n t E y bedrock surface is buried beneath more than 400 feet of unconsolidated materials E 0 R P 0 0 in the deepest parts of a bedrock valley, which cuts across southern Wabash o o 6 0 a n 3 y d d County. Most of the bedrock aquifers in the county are under confined C a d 17 2 18 r o a 0 e 13 o e 14 R 0 conditions. In other words, the potentiometric surface (water level) in most wells 15 k R 16 y W 17 18 t y 17 14 13 n completed in bedrock rises above the top of the water-bearing zone. 14 13 18 16 15 t u n o u o C The yield of a bedrock aquifer depends on its hydraulic characteristics and the C County Road 900 N nature of the overlying deposits. Shale and glacial till act as aquitards, restricting recharge to underlying bedrock aquifers.
