HUNDRED YEAR FLOOD

We had some slushy snow and rain Sunday night followed by heavy rain beginning Monday afternoon. I had about about 1.5 inches Monday and 2 inches more by 11 AM Tuesday in my rain gauge. The staff gauge on the footbridge in Abrams Park read about 9.7 feet for a flow of  1150 cubic feet/second Tuesday morning,  Unofficially, we had a 100 year rain event and a 100 year flood on Gee Creek. Public works was called out early to deal with flooding issues. Pioneer Street just east of Gee Creek had mud and debris flows and the bottom of Riemann Road was underwater as the culvert going across Pioneer backed up. North Main Avenue was closed at Depot Street as water ran across the road and formed a waterfall on the other side. The park Caretakers residence and outbuildings were flooded from a large flow where the creek had jumped its banks upstream.  It made a mess for a while but it was short lived.  By early evening the flood waters had receded and both North Main Avenue and Riemann Road were open.

The Gee Creek Trail at Heron Ridge was under some very fast moving water

The Park Caretakers residence and outbuildings were flooded.  City crews and court corrections crews worked to build a sandbag dike.

North Main Avenue was underwater until Tuesday Evening.  A larger culvert will be constructed later and this section of roadway will be raised above flood levels

   

Riemann Road near Pioneer was underwater for several hours.  There is a culvert that goes under both Pioneer and Bertsinger Road that is not large enough to handle extreme flows.

The remote site incubator normally sits a few feet off the creek.  It has 60,000 Coho eggs and fry in it and I thought they would be lost.  However, this morning I was able to get down there, restore flow, and clean the sediment off the eggs. There did not appear to be any mortality.  I visited the RSI on Allen Canyon Creek yesterday with Les Greear and that one is OK as well.
