Detailed ground water investigation of Moscow Basin. Research technical completion report, project A-011-IDA Item Info

Moscow basin, a 58 square-mile, U-shaped basin with a 12 square-mile central lowland underlain by basalt flows and sedimentary interbeds of the Columbia River Group, is a type area for the study of the small ground water basins underlain by basalt that are common in the Pacific Northwest. Because field pumping tests were not practical, mathematical models of the artesian aquifers were designed. Comparison of the performance of the model aquifers with that of the real aquifers indicates that, if no recharge is taking place, ground water in storage will meet the needs of the basin until 2050 or 2100. However, values of coefficient of transmissibility (""T"") and coefficient of storage (""S"") are very high i n the no-recharge models. If thermal values are significantly lower, then considerable recharge is taking place. No studies have been made of models that receive recharge. Model studies were used t o demonstrate the feasibility of artificial recharge utilizing seasonal runoff of intermittent streams. High contents of iron in waters in parts of the artesian aquifers are the result of naturally recharging waters carrying in iron from weathered bedrock on the margins of the basin.
