When visiting a project location, such as a bank stabilization, which data layer do you add to?
Site Visit
What is the minimum size culvert that infill can be placed inside
4 ft
What is the standard buffer on an anadromous stream on state forest land?
100 ft
What is the first thing you do when the engine dies?

Pigment breaks in the adipose fin
Length of the maxillaryWhy is it not appropriate to add site visit data to the main stream survey layer?
Some information collected in the site visit layer is not public. We have to share the main stream survey layer publicly due to grant reporting requirements.
What stream ecosystem factors are impacted by improper culvert design?
Restriction of aquatic organism movement, size selection of fish able to transit the culvert, modifying the sediment regime, and restriction of natural channel migration.
Describe the DPO process.

Why is DOT switching to aluminum culverts and what are the benefits and drawbacks
Pros - corrosion resistant, likely to last 75 years
Cons - fragile, easily bent by snow plowing and during installation, expensive, very hard to reuse

If you are surveying a stream with coho salmon and encounter a 7.5 ft waterfall, what is the minimum depth the jump pool would need to be to not be considered a barrier?
9.375 ft
1.25 X fall height
Name of the 5 common mechanical issues and their remedy
Water in the gas - drain fuel water separator
Loose electrical connections - check connections starting in the battery compartment
Gradual loss of electrical power - corrosion! Search for it and remove it with a brush and apply dielectric grease
Overheating - check the water intake ports, bad impeller, clogged water tube, bad thermostat.
Sluggish under power - boat too heavy (check the holds for water), lack of fuel getting to the block (check fuel filters), fouled spark plugs (clean off plugs or replace)

Describe the process in issuing an Over the Counter (OTC) mining permit when Kate or Greg are not available.
Determine if stream needs timing window - check catalog, and other data to see if the area has spawning fish. Inform applicant of other local restrictions.
Print out OTC form, have applicant fill in information, assign permit numbers - one permit per stream, fill in timing windows, sign, scan, give to applicant, email out to CC list, put in permit file, and add copy to projects by community folder.
