Maple Headquarters Reservoir lies within the bounds of Washington County, Oregon. Elevation runs to 197 feet. It covers about 10 acres, so this is small water you can walk round in under an hour. Banks is the closest town at 2.1 miles. The nearest city of size is Hillsboro, 9.3 miles away. The nearest edge is a long way off, so local rules apply throughout.
Depth is not on record here, which means reading the ground instead. Look for where the old bank line still shows under the surface. Draw-down through summer strips the margins, so follow the water out. Species logged across Washington County include common carp, yellow perch, brown bullhead and largemouth bass. What holds for the county may not hold for this water. On Maple Headquarters Reservoir the obvious spot is not always the productive one.
Seasonal averages run from 39°F in December up to 65°F in August. Long warm spells define the calendar more than any cold. Heat pushes fish deep from June onwards, so start early. Spring and autumn carry the year; summer squeezes it into the ends of the day. Maple Headquarters Reservoir runs to its own calendar within the local pattern.
Public sources are silent on who controls the bank. A carry of half a mile from the nearest parking is the price of fishing here. A platform or pier sits within half a mile. A small crankbait along the drop and a worm in the thick stuff cover the bass. Parking space is the usual limit rather than the bank itself. Rules for boats are stricter than rules for the bank in many places. Raymond Dierickx Reservoir sits 0.4 miles off and takes the overflow. Check the position at Maple Headquarters Reservoir before loading the car.
