News Release

San Juan Basin Royalty Trust
Declares Monthly Cash Distribution

     FORT WORTH, Texas, September 19, 2006 — Compass Bank, as Trustee of the San Juan Basin Royalty Trust (NYSE:SJT), today declared a monthly cash distribution to the holders of its units of beneficial interest of $10,541,460.83 or $0.226169 per unit, based principally upon production during the month of July 2006. The distribution is payable October 16, 2006, to unit holders of record as of September 29, 2006.

     Gas production for the properties from which the royalty was carved (the “Underlying Properties”) totaled approximately 3,532,644 Mcf (3,802,884 MMBtu). Dividing revenues by production volume yielded an average gas price for July 2006 of $6.30 per Mcf ($5.85 per MMBtu) as compared to $5.35 per Mcf ($5.02 per MMBtu) for June 2006. The average gas price may vary significantly from the posted index price for the San Juan Basin. The index price is a gross sales price, and the revenues used in the calculation of average gas prices are net of transportation, processing and gathering costs. Furthermore, the distribution to the Trust in any given month may include significant volume adjustments for sales in prior months that reflect pricing for those prior months. Capital costs for the month were $4,230,129. Lease operating expense was $1,917,944 and taxes were $2,260,017.

     This month’s distribution increased from the prior month primarily due to higher gas pricing and slightly higher gas production for July. Capital costs increased significantly from the previous month. Market conditions — including mild weather and above-average working gas inventories — continue to affect natural gas pricing. It is difficult to predict what effect these conditions will have on future distributions.
