Drainage: 545 sq.mi.

Drainage area at our listed put-in is approximately 545 sq.mi. (as calculated via USGS StreamStats Beta software).

A USGS gauge is at this site as of 2023-10-17, and should provide excellent record of flow here.

=============

Previously we had been using the USGS gauge on the Willow River, just over 8 miles to the SSW. Drainage at that gauge is 292 square miles. Based on relative drainage areas, flow on the Apple River in Somerset *could* be 1.866 times that gauge reading, so our virtual gauge uses that value to *attempt* to represent *likely* flows here. This gauge apparently was decommissioned/unfunded 2024-01-07.
