Here are some links of interest to Platte Lake:
USGS monitoring station (This is an automated river flow rate monitor located at the US-31 bridge over the Platte River, just west of Honor. Data from this site is an important input to our lake and river models. The PLIA and MDNR reimburse the USGS for its operation. It's interesting to watch the river flow react to unusually dry or wet weather or to storm events, and to see how current flows compare to historical averages. The USGS maintains a number of these customer-funded stations across the country.)
