Contains ~ 18,400 depth-specific measurements, 1,821 Secchi transparency measurements, 2,270 TSS measurements, 2,745 TP measurements, and 2,014 Chla measurements.Of the 3,262 samples, 1,479 are “complete” (SD, TSS, TP, Chl > 0) with 1,033 are from non-Inflow sites (Outflow + Mid-lake), and 796 are from 2006-present (= Program).Of the 3,262 samples, 1,061 are from Intensive reservoirs with 663 from non-Inflow sites (Outflow + Mid-lake), and 435 were collected from 2006-present.
Intensive reservoir characteristics:SA: 256-1328 ha (632-3280 acres); zmax = 4.8-20.9 m; WA:SA: 21-293
