Overview

The West Gravel Lakes are old gravel pits along the South Platte that Thornton manages as a fishing facility. They're deeper than most city ponds, which makes them some of the better north-metro water, and also some of the most heavily fished.

Fishing pressured city water

Know before you go

The facility is gated, with posted hours. Rules and fees can change, so read the signs at the gate. Water levels in gravel pits rise and fall; low water concentrates the fish but can make some banks hard to fish.
