Fishing Arnold Reservoir in San Bernardino County, California

• Overview

  Arnold Reservoir is a San Bernardino County water, in California. The sea is 25 miles distant. The water covers some 29 acres, so pick a bank rather than trying to cover it all. Chino Hills lies 1.6 miles from the water. Beyond it, Diamond Bar at 2.9 miles and Los Serranos at 4.7 miles. Rules can differ a short way off, since the county line is near.

• Where to Fish on Arnold Reservoir

  We hold no depth figure for this one. Held water runs deepest at the wall and shallows back to the inflow. A reservoir gives you a hard edge, a shelf, and not much else. Biodiversity records within roughly six miles include green sunfish, common carp, koi and arroyo chub. Records show what people reported, not what is stocked. Arnold Reservoir repays a walk before the first cast.

• Seasonal Patterns

  Average temperature peaks around 74°F in August and bottoms out near 54°F in January. There is no dead season here at all. October and November give a second good stretch as it cools. Late winter often fishes better here than midsummer does. At Arnold Reservoir the season follows that pattern closely.

• Tackle & Baits

  Nothing in our records says who may fish here. Parking is not close: half a mile from the bank, and no nearer option is mapped. Toilets show in mapping about half a mile away. Carp respond to sweetcorn or boilies fished patiently on the bottom near feeding areas. Ask in the nearest town if you are unsure. Keep proof of licence with you rather than in the car. For a change of water, Lake los Serranos is 4.5 miles distant. Check the current arrangement for Arnold Reservoir.
