Effects Of Meadow Erosion And Restoration On Groundwater Storage And Baseflow In National Forests In The Sierra Nevada, California

Title
Effects Of Meadow Erosion And Restoration On Groundwater Storage And Baseflow In National Forests In The Sierra Nevada, California
Abstract
Historical evidence indicates that prior to approximately 1930, most Sierra Nevada meadows were not incised and had perennial surface flows. Meadow erosion probably started in the late 1800's and continues to the present, but most of the erosion apparently occurred between 1930 and 1960. The limited available streamflow records for large watersheds that include substantial areas of meadow do not indicate any major secular changes in streamflow that can be attributed to meadow erosion. However, streamflow records for locations downstream of eroded meadows show less consistency in relation to precipitation than do records for the Merced River, downstream of large but unincised meadows.
Purpose
The purpose of this report is to evaluate the role of meadow erosion and restoration in storing and releasing groundwater on NFS lands in the 10 Sierra Nevada National Forests: Modoc, Lassen, Plumas, Tahoe, Lake Tahoe Basin, Eldorado, Stanislaus, Sierra, Sequoia, and Inyo.
