Harrison Airport serves Welch, Oklahoma at 805 ft elevation with its longest runway, 03/21, at 4,600 by 40 ft. The figures below are computed from FAA NASR runway data (via OurAirports) and the same rules of thumb JetDesk uses on the airport page in the app; the POH and current NOTAMs are the authority.

02Density altitude and turboprop runway margins

Standard temperature at 805 ft is about 13°C. Every 1,000 ft of density altitude adds roughly 8 percent to a turboprop's takeoff distance and 5 percent to its landing distance. The table uses Piper Meridian book numbers (2,438 ft takeoff and 2,110 ft landing over a 50 ft obstacle at sea level, ISA, max weight) as a reference airplane; heavier turboprops and light jets scale the same way from their own POH figures.

Conditions	Density altitude	Takeoff est.	Landing est.	Landing × 1.5
Standard day (ISA, 13°C)	805 ft	2,595 ft	2,195 ft	3,292 ft
Warm day (ISA +10)	2,005 ft	2,829 ft	2,322 ft	3,482 ft
Hot day (ISA +20)	3,205 ft	3,063 ft	2,448 ft	3,672 ft
35°C afternoon	3,398 ft	3,101 ft	2,468 ft	3,703 ft

Planning aid only. Even on a 35°C afternoon the longest runway (03/21, 4,600 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,703 ft needed). The percentages are a generic rule of thumb applied to one reference airplane, not certified performance data for any specific aircraft, and the runway size categories describe the runway, not your airplane's suitability. Verify with the approved flight manual before every flight.

03Nearby fields with 5,000 ft or more

Useful as alternates, as fuel stops when the price at 3OL8 is high, or as the longer runway on a hot afternoon.
