About this lake
About Knoll Lake
Knoll Lake in Arizona offers swimmers a pristine mountain retreat nestled in the scenic high country of the Apache-Sitgreaves National Forest. This charming alpine lake captivates visitors with its stunning natural beauty, surrounded by towering ponderosa pines and granite peaks that create a serene backdrop for water activities. The lake's crisp, cool waters and unspoiled wilderness character make it an ideal destination for those seeking an authentic Arizona swimming experience away from crowded urban pools. The crystal-clear water reveals the rocky bottom, providing an invigorating swim that rejuvenates body and spirit. Wildlife viewing opportunities abound, with possibilities of spotting deer, eagles, and other forest inhabitants. The peaceful atmosphere and relatively undeveloped shoreline preserve the lake's natural charm while accommodating swimmers of varying abilities. Two practical tips: arrive early during peak season to secure parking and optimal swimming conditions, and bring a wetsuit or rash guard as water temperatures remain cool year-round due to the lake's elevation.
About This Lake
Swimming Conditions
Knoll Lake features crystal-clear water with excellent visibility, allowing swimmers to see the bottom in most areas. Water temperature averages 68-72 degrees Fahrenheit during summer months, making it refreshing but requiring acclimation for first-time swimmers. The lake maintains moderate depths ranging from 8 to 25 feet, with a gradual slope near the shoreline ideal for wading before deeper ventures. Swimming conditions are generally very calm, protected by surrounding forest that blocks strong winds. The main swimming area near the developed shore offers the safest entry points with sandy bottom approaches. No lifeguards are present, requiring swimmers to exercise personal responsibility and swim with buddies. Currents are minimal due to the lake's contained basin and peaceful nature. Water quality remains consistently good throughout the swimming season. Safety considerations include the cool water temperature, lack of lifeguard supervision, and the remote location requiring self-sufficiency. Swimmers should assess personal swimming ability before entering deeper sections and always inform someone of your location.
