 | | During the period 1950 through 1975, the water table steadily declined in much of the Cache Creek sub-basin, in the Lower Cache-Putah sub-basin and on the western side of the Colusa sub-basin (Scott, et al., 1975; DWR, 1961). |
 | | Heavy pumping, coincident with the lowering of the Cache Creek thalweg from aggregate mining, was responsible for declines in the Hungry Hollow area, in the Yolo/Woodland area and in the areas on both sides of the Creek from Esparto Bridge to Yolo (Wahler Associates, 1981). |
 | | Since 1975, with the ordinance on in-stream mining to protect the thalweg, and introduction of supplemental Indian Valley surface supplies in the Hungry Hollow area, declining water levels have been reversed, or stabilized in the part of the Cache Creek sub-basin west of the Plainfield Ridge. |
