Lake Belton is a US Army Corps of Engineers reservoir on the Leon River in Bell County, Texas, completed in 1954 for flood control and water supply. At normal pool elevation of 594 feet MSL, the lake covers approximately 12,300 acres and reaches a maximum depth of about 124 feet near the dam. It is best known statewide for its landlocked striped bass, but the full fishery runs from white bass runs in spring to blue catfish in the main channel year-round.
This page covers the actual depth numbers, the fish species tied to each depth zone, and the seasonal patterns that determine where those fish are on any given month.

Depth Zones and Fish Species
Lake Belton's fish populations respond to water temperature and available structure. The reservoir's three main arms fish differently from each other: the Leon River arm is deepest and holds the primary striper population, Cowhouse Creek arm is shallower with warmer water that draws crappie and white bass, and Nolan Creek is the shallowest of the three and best for largemouth. Knowing which arm a species prefers cuts down searching time significantly.
Shallow Flats and Coves: 0-15 Feet
Primary species: Largemouth bass, black crappie (around dock pilings and brush), channel catfish on soft bottom flats, white bass in spring near tributary mouths.
The shallow zone dominates the upper ends of all three tributary arms and along rocky points and coves throughout the lake. In spring, largemouth bass move to 5-12 feet to spawn on gravel and rock flats. Crappie hold around any vertical structure they can find: dock pilings, submerged brush piles, and fallen timber. Small crappie jigs and minnow rigs under bobbers work best at this depth. Channel catfish cruise soft-bottom flats from 8 to 15 feet at night.
Mid-Range Structure: 15-40 Feet
Primary species: Striped bass (winter through spring), white bass (spawning run and post-spawn), largemouth bass on deeper structure, blue catfish along channel edges.
The 15-40 foot range is the most productive depth zone on Lake Belton for most of the year. Striped bass school over main-lake humps and channel bends at this depth from December through May, feeding on shad near the surface before dawn and retreating deeper as the sun rises. Drift fishing with live shad or umbrella rigs over points in 20-35 feet is the most consistent technique. Topwater fishing for stripers can be exceptional at dawn and dusk when they push shad to the surface in this zone.
White bass school in this range year-round, moving toward shallower tributary arms in February through April for the spawning run. After the run, they scatter over main-lake humps in 15-25 feet and respond well to inline spinners and small blade baits.
Deep Channel: 40-80 Feet
Primary species: Striped bass (summer), blue catfish along channel edges, white bass (late summer).
As summer water temperatures climb above 85 degrees F at the surface, striped bass push into the deep main channel of the Leon River arm to find cooler, more oxygenated water. The 40-80 foot range is the summer striper zone. Finding them requires a quality fish finder with side-imaging to locate suspended schools over the channel without idling directly over the fish and pushing them down. Blue catfish stack along the steep channel edges at this depth, particularly near structure transitions. Cut shad on Kahle hooks fished on the bottom at channel edges produces large blue catfish at this depth range.
Fish finder pick for deep channel: Humminbird Helix 7 MEGA DI with MEGA Down Imaging shows suspended stripers in 40-80 feet with enough resolution to distinguish individual fish from the school.
Dam Area: 80-124 Feet
Primary species: Striped bass (hottest summer days), blue catfish.
The deepest water at Lake Belton sits in the main channel near the dam on the southeast end of the lake. During the hottest stretches of a Texas summer, striped bass may push to 80 feet or deeper seeking the coolest available water. These fish are less actively feeding and harder to trigger. The most consistent method is vertical jigging directly over the school shown on your fish finder, or drifting live shad on a downline rig. Not all striper populations make this depth transition; some fish hold in the shade of dam structures at more moderate depths. Access to the near-dam area is subject to USACE safety zones; follow posted restrictions.

| Leon River arm (main body) | 50-80 ft | Main lake channel, points and humps | Striped bass, white bass, catfish |
| Cowhouse Creek arm | 20-35 ft | Shallow, warmer water, more vegetation | White bass, crappie, largemouth |
| Nolan Creek arm | 15-25 ft | Shallowest arm, rocky and wooded banks | Largemouth bass, crappie, channel catfish |
| Main lake humps and points | 15-40 ft | Hard bottom structure, shad-holding | Striped bass, white bass |
| Upper tributary flats | 5-15 ft | Silty, soft bottom, brush | Channel catfish, crappie, spawning bass |
Seasonal Depth Patterns
Winter (December-February)
Lake Belton in winter is one of the best striper windows of the year. Water temperatures in the low 50s to upper 60s F slow the fish's metabolism but keep them active and concentrated. Stripers school tightly on main-lake humps and channel bends in 15-35 feet. Big schooling fish often push bait to the surface on calm mornings, creating explosive topwater feeding opportunities. Pencil poppers and bucktail jigs in white or chartreuse produce in this window. Blue catfish are active in the main channel even in cold water, targeting cut shad on the bottom in 30-60 feet.
Spring (March-May)
Spring is the most active multi-species season. White bass begin their spawning run as water temperatures rise to 55-60 degrees F, moving from the main lake up into the Cowhouse Creek and Leon River arms. Largemouth bass spawn in 5-12 feet on gravel and rocky flats. Crappie stack around dock pilings and brush piles in 8-20 feet, making this the best crappie season on the lake. Striper action stays strong through May before heat pushes the fish deep. A Garmin Striker Vivid 5cv is enough unit for spring fishing across all zones.
Summer (June-August)
Summer is the most technical season on Lake Belton. Surface temperatures in the mid-90s F push stripers to 40-80 feet in the main channel, and they feed in short windows at dawn and dusk. The best summer striper technique is live-lining shad on a downline rig over the school shown on your fish finder, anchored up-current so the bait drifts naturally through the school. Bass and crappie retreat to shade under docks and deeper brush. Night fishing for blue catfish on the channel edges in 30-60 feet with stink bait or cut shad produces well when daytime fishing slows.
Fall (September-November)
Fall is the most forgiving season. As surface temperatures drop below 75 degrees F in September and October, stripers return to the 15-40 foot zone and feed aggressively on shad schools building up reserves before winter. Topwater explosions return at dawn and dusk. Largemouth bass are active on main-lake points and off rocky banks in 10-25 feet. White bass school over main-lake humps and respond to blade baits and small swimbaits. For reading the solunar calendar to time peak feeding windows, see our solunar fishing forecast guide.
Choosing a Fish Finder for Lake Belton
Lake Belton's fishing depth ranges from 5-foot shallow flats to 80-foot main channel for summer stripers. No single unit needs to handle 400-foot Great Lakes depths, which means mid-range CHIRP units are more than sufficient for most anglers.
| Use Case | Depth Range | Recommended Unit |
|---|---|---|
| Crappie and bass fishing, shallow arms | 5-25 ft | Lowrance HOOK Reveal 5 |
| White bass and striper, main lake humps | 15-40 ft | Garmin Striker Vivid 5cv |
| Summer striper, deep channel | 40-80 ft | Humminbird Helix 7 MEGA DI |
| Near-dam striper, catfish channel | 60-124 ft | Lowrance HDS-9 Live |

Frequently Asked Questions
How deep is Lake Belton?
Lake Belton reaches a maximum depth of approximately 124 feet near Belton Dam at normal pool elevation (594 ft MSL), according to USACE and TPWD data. The average depth across the reservoir is roughly 26 feet. The deepest water is concentrated in the main Leon River arm near the dam; the tributary arms (Cowhouse Creek, Nolan Creek) are much shallower at 15-35 feet.
What is Lake Belton best known for fishing?
Lake Belton is best known for its landlocked striped bass fishery, one of the strongest in Texas. The reservoir also offers excellent white bass during the spring spawning run, largemouth bass on rocky structure, blue and channel catfish in the main channel, and black crappie around brush piles and dock pilings. TPWD stocks stripers regularly to maintain the population.
Where do striped bass hold in Lake Belton?
Striper location on Belton changes with season. Winter through spring: 15-35 feet on main-lake humps and channel bends in the Leon River arm. Summer: 40-80 feet in the deep main channel as fish seek cooler water. Fall: return to 20-40 feet as surface temperatures drop, feeding aggressively before winter. Dawn and dusk topwater action is possible in all seasons except midsummer.
When do white bass run on Lake Belton?
White bass begin their spawning run as water temperatures reach 55-60 degrees F, typically late February through April. They move from the main lake into the shallower tributary arms, particularly Cowhouse Creek and the upper Leon River arm. Inline spinners, curly-tail jigs, and live minnows in 5-20 feet of water near current breaks are the top techniques. The run usually peaks in March.
What fish finder do I need for Lake Belton?
For shallow-arm fishing (crappie, bass, spring white bass), a basic CHIRP unit like the Lowrance HOOK Reveal 5 handles the 5-25 foot range well. For summer striper fishing in 40-80 feet, upgrade to a unit with side-imaging to locate suspended schools without spooking them. GPS lake maps with contour lines for Belton (available via Navionics or C-MAP) make it much faster to find the channel bends and humps where stripers concentrate. See our full fish finder guide for model comparisons.
