Lake Somerville depth map and depth chart

The Texas Water Development Board surveyed the lake bed in April 2012, so the deepest point is a measured figure rather than an estimate.

Deepest point
29 ft
Average depth
13.2 ft
Surface at full pool
11,395 acres
Volume at full pool
150,293 acre-feet

Measured from the conservation pool at 238 ft down to the deepest surveyed point at 209 ft. Depths quoted against a flood pool or an older survey come out higher.

Questions people ask about Lake Somerville

Answered from the same readings as the rest of this page. Where we have no basis for an answer, there is no entry — spot-by-spot local knowledge is not something we can claim for Lake Somerville.

Is it worth fishing Lake Somerville today?
5 out of 10 — picky. Work for it. The strongest stretch is 3:28 AM–5:28 AM. That number is worked out fresh each morning from the solunar windows, the pressure trend, the water level.
What time should you fish Lake Somerville?
Today's major windows run 3:28 AM–5:28 AM and 3:52 PM–5:52 PM, with minor windows at 11:07 AM–12:07 PM and 9:32 PM–10:32 PM. Sunrise is 7:10 AM and sunset 7:31 PM. A major landing on first or last light is the stretch worth setting an alarm for.
What is the water temperature at Lake Somerville?
No gauge on Lake Somerville measures it, so this is an estimate: roughly 84.2°F, worked out from the 7-day mean of air temperature at NOAA weather station K11R (Brenham, Brenham Municipal Airport). Checked against the lakes that do have a thermometer, that method lands within about 4.5°F of the real reading and was off by 8.3°F at worst. Treat it as a ballpark, not a measurement — and note the bite index above ignores it entirely, because an error that size would move the verdict as often as it would fix it.
What is the water level at Lake Somerville right now?
236.93 ft, read at 7:00 AM from USGS station 08109900. Over 24 hours it is down 0.02 ft.
Are water levels rising or falling at Lake Somerville?
Falling. The lake is down 0.02 ft in 24 hours and down 0.13 ft over the week. Over the last 8 days it has held between 236.93 and 237.15 ft. Every figure here is a difference between two gauge readings, not a forecast — what the level does next depends on rain and on what the dam releases.
Is Lake Somerville full right now?
At 236.93 ft the lake is 1.07 ft below its conservation pool of 238 ft, as Texas Water Development Board defines it. That is a comparison of two elevations, not a percentage of capacity — a reservoir at half its depth holds far less than half its water, so the two are not the same thing.
Can you eat the fish you catch in Lake Somerville?
That is a health question, and it is answered officially rather than by us. Texas Department of State Health Services publishes the fish consumption advisory covering these waters, where an interactive viewer shows advisories and possession bans by waterbody. Read it before you keep a meal — we give no eating advice.
Do you need a licence to fish Lake Somerville?
Yes. A Texas fishing license covers this water, required from age 17. TPWD sets the rules and is the one that counts.
What size fish can you keep in Texas?
It depends on the species, and several have slot limits rather than a simple minimum. Open to harvest today: red drum (redfish), spotted seatrout (speckled trout), black drum, southern flounder. Seasons here change mid-year by agency order, so the status is re-checked every morning.
