The Lowell Creek Diversion Tunnel is a flood control project located in Seward, Alaska, United States. The project was constructed to alleviate flooding of Lowell Creek in Seward. It was the first flood control project completed by the United States Army Corps of Engineers in Alaska.
Originally, Lowell Creek ran through Seward along what is now Jefferson Street. Beginning with the town's establishment in 1903, the fast-moving stream produced one to three severe floods a year until the tunnel was built in 1939. The floods carried large amounts of debris from the mountains; one flood deposited 10,000 cubic yards in an 11-hour period in 1935.
In 1927 the Alaska Railroad constructed a small diversion dam and flume to carry debris down Jefferson Street to drain into Resurrection Bay. However, by 1937 these structures had deteriorated beyond repair. Consequently, the Army Corps of Engineers began construction of the new project in August 1939. The project consisted of: a diversion dam, 400ft in length and up to 25ft high that diverted the creek away from its original path;a tunnel through Bear Mountain, 2068ft in length and 10ft in width;an outlet flume, 109ft in length and 10ft in width which drains into Resurrection Bay. Completed in 1940, this system withstood the 1964 Alaska earthquake, as well as severe floods in 1966, 1986, and 1995, which brought the water level within inches of cresting the dam.

Lowell Creek Waterfall Reviews
We stopped by to see the waterfall. It was interesting and it did not take much time to see the waterfall. more »
I was surprised when I came around the corner and saw this waterfall. There were people standing on the bridge watching then would run down to the base, throw their rods in and come out with fish... more »
This is a waterfall that falls, apparently, into a construction site... If that sounds interesting, I highly recommend you check it out! If you're bored, it's a great way to kill five minutes. But Seward is beautiful and you shouldn't go out of your way to check this out.
It's a gravel place to stop, under construction as of July. The hills have warning throughout of falling rock. This waterfall is also a release to prevent falling of rocks due to water cracks. Next to it is a floater plane flying area which is amazing and it you have few hrs to just sit and relax, you might end up seeing few parked there
