Summary

Median summer water yields and resultant flows are used in Michigan to regulate large water withdrawals to help prevent negative effects on characteristic fish populations. Large water withdrawals commonly are associated with irrigation in rural areas. In an earlier statewide report, an index-flow statistic for the period of record, defined as the median flow during the summer month of lowest flow, was used to characterize median summer flows and associated water yields. In this report, the annual series of median summer water yields for the period July 1 through September 30 within the period of record is used to characterize median summer water yields. For 27 streamgages included in both reports, the average index water yield was [...]

Purpose

All data provided in this report were based on previously published sources of information, although some processing occurred that changed units of reporting or that involved spatial approximation. In particular, irrigation data compiled by the Michigan Department of Environmental Quality that were aggregated to the county level, were used to approximate irrigation in hydrologic basins. In addition, monthly precipitation and temperature data were compiled by NHDPlus (ver. 2) catchments (McKay and others, 2018) and aggregated to the basin level. Approximations also occurred in this process as the boundaries of the most downstream catchments were not always coincident with the location of the streamgage site, which defined the hydrologic boundary. The data are provided for convenience in reproducing results presented in USGS Scientific Report 2018-5071.
