Latest Status Report

Last Updated: April 17, 2019

Aspinall Unit Reservoirs – As of April 10, 2019 releases from Crystal Dam are approximately 850 cfs. Uncompahgre Valley Water Users Association has begun diversions through the Gunnison Tunnel and flows through the tunnel as of April 10, 2019, are 400 cfs.  Flows through the Black Canyon are approximately 430 cfs. There is currently about a 20 cfs loss to the Gunnison River between Crystal Dam and the Gunnison Tunnel Diversion.  As of April 10, 2019, Blue Mesa Reservoir elevation is 7439.74 feet which correspond to storage content of 258,294 af (31 percent of capacity). The elevation of Blue Mesa is beginning to rise as inflows due to run off are increasing.

The March unregulated inflow to Blue Mesa Reservoir was 27,700 af (77 percent of average). Unregulated Inflows to Blue Mesa for the next three months (April, May and June) are projected to be: 83,000 af (108 percent of average), 270,000 af (122 percent of average) and 420,000 af (161 percent of average), respectively. For water year 2019, the unregulated inflow volume is forecasted to be 1,169,500 af (122 percent of average) with 925,000 af (137 percent of average) of unregulated inflow occurring during the April through July period. The April 24-Month Study is reflective of this new forecast.

Current projections indicate Blue Mesa storage will steadily increase as spring runoff begins. Snowpack conditions in the Gunnison River Basin are well above normal at 143 percent of median above the Aspinall Unit. Current projections indicate Blue Mesa will nearly fill by late summer if current inflow forecasts come to fruition.  The peak elevation for this water year will occur in or around late July and is projected to be about 7515 feet. The projected end of water year 2019 elevation of Blue Mesa is 7507.5 feet which correspond to a live storage content of about 724,000 acre-feet (87 percent of full capacity).

Epic Snowpack In Colorado Rocky Mountains

Spring Forecast For Morrow Point & Blue Mesa Reservoirs

The 2018/19 Winter season began with most of Southwest Colorado in an exceptional drought. A late start to snowfall was discouraging until things changed at the end of December 2018 when the jetstream began favoring the four corners region. It has been snowing ever since. The current snowpack is 154% above average.

Happy Spring 2019!

Although Spring is in the air here in Gunnison country, WE HAVE SNOW and LOTS OF IT! The much-needed snowfall this past Winter means that the reservoirs will have plenty of water this year ... now it's the waiting game.

When will Ice off happen? It is anybody's guess at this point, but what is for sure is that Spring and pre-runoff fishing is perhaps the best of the year for hungry, trophy sized, trout bite... We hope to be trophy lake trout and brown trout fishing within the month on Blue Mesa, the latest I have ever seen boats launch on Blue is April 27th. So, we are optimistic about a mid-April start. On Morrow Point we will try to launch the boats on May 1st, this can seriously be the best fishing in the state that week. These fish are hungry, very gullible and very catchable... COME FISH PRE RUNOFF with us!

Check out some fishing highlights video clips from Morrow Point HERE.

Looking to launch the boats May 1st. come fish the non-pressured trout of May with us.

Fishing Report

June on Blue Mesa = excellent Kokanee Fishing

June has been great for GSO on Blue Mesa. Kokanee fishing has been as good as it gets and the fish are healthy and HUGE. We still have some days open in July and the fishing should stay just as good as it is now.





Also we have been doing some Fly Fishing trips around the Blue Mesa’s waters. Consider us for your next fly fishing trip in the Gunnison valley


Blue Mesa Lake Trout

Trophy lake trout season has been good to GSO so far. Not gonna say it’s been easy, but finding a way to produce fish for clients on most trips!! With low water levels we’re finding some fish in new spots and been trying lots of new lures and tactics to induce a strikes> its been fun re-learning the lake at this water level. The bad news for good fishing this season is that many of the old trophy sized fish are being harvested by some anglers daily. It’s so sad to see people have no consideration for the fishery that they love so much. It’s so sad to see these old fish end up on stringer. I heard of one boat keeping 17 mackinaw one day,  half of which were old big fish and another that had 5 over 3olbs one day! sad sad sad, very ignorant and very disrespectful to an amazing fish that takes so long to grow that big! Please consider this lake trout  fishery for the future generations of anglers that will want to catch these fish and not just here the stories from you about how many 30lb’ers you threw on the grill years ago!
