Things have changed and will change on BC

newlocation1
Yesterday, while showing FRA customer Norm some of my favorite spots on Boulder Creek, I was startled to find out that this spot near the first climbing area, was completely different. The water is low now so I was able to scope out the terrain that I used to know like the back of my hand. When the water comes up this is going to be completely different. Furthermore, there is still debris and unprotected banks that will change shape during runoff.
Here are some predictions from Boulder County:
  • Second week of May is best guess of the beginning of spring run-off based on NWS predictions (any unexpected warm spell before then could accelerate)
  • Problems with creek and bank erosion – many creeks are following new paths
  • Snowpack is currently 168% – 248% of normal – reservoirs are already full, so spillover may occur earlier than normal during run-off
  • Flash flood potential is high, especially if thunderstorm activity accompanies run-off
  • Major landslides are not predicted; however, area water tables are very high and will likely remain high for several years, so some slides are possible
  • Debris remains a high hazard, especially debris located in remote sections far from homes and roads (extremely difficult and expensive to remove)
Citizens were asked to promptly report (via calling 911) any of the following NEW events:
  • Sudden river/creek bank erosion, sediment build-up around culverts and bridges
  • NEW hazardous debris appearance; any major drop in water flow that might be due to debris dams
  • Rock falls and/or changes in stream flow/direction
  • Sudden tilting of power poles and trees near roads
